Why would I replace the cap?

The cap contains a rubber seal preventing moisture and dirt from entering the stem and contaminating the seal of the valve core. The cap is an integral component in the sealing system of the TPMS sensor and should be replaced together with the rest of the components in the service pack at each tire change.

Why would I replace the valve core?

Heat and compression will eventually cause deterioration of rubber and plastic components. Replacing the valve core is vital to prevent slow leaks. Do not re-use a valve core. Replace with a new electroless nickel plated valve core for aluminum valves with each tire change.

Why would I replace the nut (for clamp-in sensors only)?

The anodized aluminum nut prevents metals from the possibility of galvanic corrosion. You should only use nickel-plated valve cores on aluminum valve stems. Additionally, torquing and retorqueing the nut multiple times may damage the threads to the point of failure. A new nut ensures accurate torquing.

Why would I replace the rubber valve (for snap-in sensors only)?

Since the rubber valve is constantly exposed to various environmental and weather conditions, it will inevitably experience more wear and tear along with aging. Replace the valve evert every time you change the tires. changed.

Why would I replace the grommet (for clamp-in sensors only)?

The grommet – the sealing gasket between the stem and the wheel rim hole – is subject to intense compression and high temperatures causing the grommet to adapt its shape to the rim surface. For a secure air seal, replace the grommet together with the other components in the service pack at each tire change.

Why would I replace the valve screw?

The valve screw is a self-tapping threaded screw that connects the valve to the sensor body to ensure a secure connection. The screw cannot be used a second time, so you will need to replace the screw.

What if the DVT Pro-Select sensor is incorrectly programmed and installed in the tire?

The DVT Pro-Select and DVT-PRO can simply be reprogrammed right through the tire.

What is a TPMS rebuild kit?

A TPMS rebuild kit contains all the components to rebuild the TPMS sensor’s valve. Replacement is recommended any time your tires/TPMS receive service. A rebuild kit includes:

  • Hex Nut 
  • Washer(s) 
  • Valve Core 
  • Rubber Grommet 
  • Plastic Valve Cap

My TPMS stem is corroded but the sensor still works. Can I replace just the stem?

  • If you have a 1-piece style sensor, you cannot replace the stem. 
  • If you have a 2-piece style sensor, you can replace the stem and can service the sensors with a rebuild kit.

I have dark tinted windows. Will the tint interfere with the OEM relearn?  

Sometimes tinted windows interfere with the OEM relearn. We recommend rolling the windows down until the OEM relearn is complete.

I have Bluetooth accessories installed in my car. Will those accessories interfere with the OEM relearn?

Sometimes Bluetooth devices will interfere with the OEM relearn. We recommend unplugging these devices until the OEM relearn is complete.

Can aftermarket accessories interrupt the TPMS signal or prevent it from communicating with my vehicle?

Absolutely. Large custom wheels, metallic window tint, certain wireless and/or Bluetooth devices and even a plug-in charger can block the signal creating a constant or intermittent system fault.

I need help!

Give our Dynamic Tech Support a call Monday – Friday 8 a.m. – 5 p.m. ET. at 1.800.805.4058.

How do I program sensors?

Using one of many supported TPMS programming tools, select: YEAR – MAKE – MODEL & Dynamic. The tool will instruct which DVT sensor to use. The tool will program the sensor(s) based on your vehicle. Finish any installation needed, and perform the OE relearn (see the Application Guide for the specific procedure).

Can I simply replace the battery?

No! The battery cannot be replaced. The housing is sealed to protect internal components, so always replace the entire sensor and never just the battery.

What do I do with the old sensors? 

You can dispose of them properly. Make sure to dispose the old sensors at least 100 feet from the vehicle to prevent interference during the relearning of your new sensors.

Can I bypass or disable the TPMS system?

No. Under 49 U.S.C. 30122(b), “A manufacturer, distributor, dealer or motor vehicle repair business may not knowingly make inoperative any part of a device or element of design installed on or in a motor vehicle or motor vehicle equipment in compliance with an applicable motor vehicle safety standard.”

I replaced my TPMS sensors, and I finally have working sensors, but the registered PSI number is about 3 PSI low on three accurate tire gauges. Is this normal?

Your vehicle dashboard gives you an accurate pressure reading while your shop gauge displays a relative pressure. A conventional shop gauge may display different results based on environmental factors like altitude and weather. The TPMS Pressure Gauge will always display the exact PSI it receives from the sensor inside the tire.

My car has TPMS. I haven’t had it serviced yet at my repair facility. What should I expect when I get there? 

You should expect the following:

  • Service or replacement of any nonfunctioning component of your TPMS sensors 
  • Replacement of TPMS sensor sealing components (cap, core, grommet and nut) 
  • A “relearn” of your TPMS sensors to your vehicle’s computer to program correct positioning of TPMS sensors 
  • Verification that your TPMS system is functioning properly after tire service is complete

Where do I find my vehicles recommended Pounds Per Square Inch (PSI)?

To identify your vehicle’s recommended PSI, check the tire placard. The tire placard is an informational label put on your vehicle by the original equipment manufacturer, normally located inside the driver’s side door frame or doorpost. It may also be on the edge of the driver’s door or the inside of the glove box door or trunk lid. It contains information including the vehicle manufacturer’s recommended tire pressure for your vehicle, the recommended tire size, and the maximum load you should have in your vehicle. This information is also located in your owner’s manual.

Why does tire pressure change? 

Many factors affect tire pressure including ambient temperature changes and tire damage, like a puncture. Tire pressure drops about 1 PSI for every 10°F drop in ambient temperature. Additionally, tires can lose as much as 1.5 PSI per month as air escapes the tire and rim naturally.

What does an under inflated tire look like?

You cannot always tell if a tire is under inflated simply by looking,  kicking, or pressing on the tire. The only way to accurately check tire pressure is by measuring the tire pressure with a quality pressure gauge.

How does weather and temperature affect tire pressure?

Winter tires can wear out if used in prolonged hot conditions, and summer tires have lower resistance in slippery conditions. Customers who invest in seasonal tires will likely ask you when they need to change from their winter tires to their summer tires (and vice versa).

The magic number is 45°F. When temperatures are consistently above that mark, drive on summer tires. When temperatures are regularly below that mark, make the switch to winter tires. During each changeover, a technician should check the TPMS valves and sensors on all of the tires.

How often should I check my tire pressure?

A tire doesn’t have to be damaged or punctured to lose air. All tires will lose air naturally over time, so it’s recommended to check the pressure in all your tires, including the spare, at least once per month. Road conditions, weather conditions or other circumstances may warrant checking the pressure more often. Remember to always use a quality tire gauge when checking tire pressure, and don’t forget the spare! It may not have TPMS but check the pressure anyways in case you need your spare for an emergency.

My warning light keeps coming on. What does that mean? 

The TPMS warning light will illuminate if your vehicle’s tire pressure is too low or part of the TPMS system malfunctioned in any of your wheels. The light will do one of two things:

  • A blinking light means the TPMS is malfunctioning. One or more sensors may have failed or lost communication. Sensor failure may occur due to a dead battery (sealed inside the sensor), damage, or from natural wear and tear. Most sensors last 8 – 10 years.

A solid light means one or more tires is operating at an unsafe pressure. Check your tires immediately.

What are the benefits of TPMS?

TPMS provides safety and economic benefits. TPMS monitors the air pressure in a tire and sends a warning to the vehicle’s on-board monitoring system (on the dashboard) when the pressure drops below a preset limit. By helping drivers maintain proper tire inflation, TPMS can help improve ride and handling, reduce stopping distances and the potential for hydroplaning, increase miles per gallon, and extend tire life.

Why do I have TPMS in my Vehicle?

As of 2007, the United States Department of Transportation (through NHTSA) requires a Tire Pressure Monitoring System to all new passenger cars, multipurpose passenger vehicles, trucks, and buses that have a gross vehicle weight rating of 10,000 lbs. or less (except those vehicles with dual wheels on an axle). The legislation requiring TPMS passed in reaction to Congressional hearings on vehicle rollover deaths caused, in part, by vehicles with under inflated tires.

What is Tire Pressure Monitoring System or (TPMS)?

A Tire Pressure Monitoring System, or commonly referred to as TPMS, is to warn you of at least one or more tires are significantly under-inflated, possibly creating unsafe driving conditions. This indication is made on the dashboard in the form of an ICON or other warning, or both.

Yes. We offer a variety of low-profile oil drains designed for larger vehicles that range from 17- to 25-gallons in both poly and steel. These oil drains also come with manual or air-operated pump capabilities.

Where can I purchase an oil drain?

We work with a variety of distributors throughout the United States who sell our service equipment, both in person and online. If you already have a preferred shop supplies distributor, we suggest starting with them to find the equipment you’re looking to purchase. If you don’t have a preferred distributor, fill out this form and we will connect you with the right fit.

Do I need a stand or Filter Regulator Lubricator (FRL) with my filter crusher? 

To use an oil filter crusher, you will need a stand and FRL if:

  • your shop currently does not have a place to mount the crusher; and 
  • you do not have a proper air line with FRL in place. 

Water in air lines is not a good thing for oil crushers or other air-operated equipment. We recommend a separate FRL for your oil filter crusher to maintain clean air and ensure the proper use of air pressure.

Do I need to crush my used oil filters before disposing of them? 

Because of environmental regulations, most states require repair facilities to drain or remove more than 85% of used oil from a filter before disposal. If you hang filters upside down or stack them in a corner of your shop to let the oil drip off, the process could take all day or all night. Plus, you’re taking up valuable storage space, and you may not reach that 85% mark.

An oil filter crusher removes more than 95% of the residual oil from a filter. This is a much more efficient way to dispose of used oil filters because there’s no waiting for hours for the oil to drip off. Also, compressed filters take up less space. This faster process is safer for the environment and keeps you in compliance with regulations.

How do you crush a used oil filter?

First you need to get a filter crusher. These filter crushers remove more than 95% of the residual oil from the filter and make disposal much safer for the environment.

To crush a used oil filter, you simply place one filter in the crushing chamber with the open end of the filter facing downward within the area surrounded by the six centering posts. Then you close the door to activate the crushing cycle. When the unit stops running or runs noticeably slower, the crushing cycle is complete (NOTE: the crusher will not operate with the door open). Raise the door and carefully remove the crushed filter.

How fast does the fluid evacuator work?

The more viscous the fluid the faster it will take to evacuate. Warm oil or other fluid will flow faster than colder fluids. Also gear oil may take more time to evacuate than a traditional 10W30 weight oil.

How do I know which probe to use with a fluid evacuator?

Unfortunately, there is no application data (year, make, and model of vehicle) for fluid evacuators, so you need to make sure you have the snuggest possible fit with the probe going into the dipstick. JohnDow Industries (JDI) Equipment’s fluid evacuators come with six probes that vary in width and length. Our steel fluid evacuators come with adapters for Mercedes, BMW, and Volkswagen.

What type of fluid will the evacuators work with? 

Any non-caustic or non-flammable fluids are ok to use with the fluid evacuators. The more viscous the fluid, the faster it will evacuate. Warm oil or other fluid will flow faster than cold fluids. Gear oil may take more time to evacuate than a traditional 10W30 weight oil.

How does a fluid evacuator work? 

Fluid evacuators remove used oil and other non-flammable fluids from almost any vehicle using compressed air and an on-board venturi vacuum system. They work best when the fluid is warmed up. To do this, idle the vehicle for a few minutes to get the fluids more viscous, then the evacuator will operate more efficiently.

Do I need a fluid evacuator for my shop?

Shops who do oil changes or other fluid management work should have a fluid evacuator on site. If your shop works on import vehicles regularly, chances are at some point a vehicle will come in without a drain plug, where you’ll need to perform a fluid evacuation through the dip stick. Many import vehicles do not utilize drain plugs anymore. If you come across damaged or cross threaded drain plugs from a previous shops work, evacuating the oil will save you costly additional expenses like paying for an oil pan that was damaged by another shop.

Additionally, some vehicles have skid plates blocking the oil pan. Taking this skid plate off can take up significant time. Using a fluid evacuator from the dipstick virtually eliminates this method.

Why is my drain not emptying properly? 

Most of the time, this happens when something falls into the downtube, like a nut or bolt. If this is not the issue, give us a call at 1-800-433-0708 to help you troubleshoot the issue. 

How much is an oil drain? 

Oil drains vary in price depending on features, capacity and the type of material (usually plastic or steel). For an economy-style plastic drain (like our 8- or 18-gallon oil drains), you can expect to pay around $120 – $200. Larger capacity plastic drains can be as much as $700 in some cases. For steel self-evacuating drains (like our 18- to 25-gallon oil drains), you can expect to between $250 – $800 each.

What is the right oil drain for my shop?

When you’re shopping for an oil drain, you should take a minute to ask yourself a few questions:

  1. How many oil changes are done in your shop daily? This will determine how big your oil drain needs to be.
  2. How do you store waste oil, and do you have a suction pump? This will lead you to the best oil drain style: self-evacuating or pump-assist.
  3. Do you work with expensive vehicles? This will help figure out whether to go with a poly or steel oil drain (You could damage cars with a steel version).

How big your oil drain needs to be
If oil changes are your main service, you need a large oil drain—possibly several of them. If your specialty is in another area, you can get by with a smaller oil drain.

Larger Oil Drains
You should invest in a large oil drain if changing oil is the main focus for your shop. A 25-gallon or 27-gallon oil drain would be ideal if you do a significant amount of oil changes on a typical day. You may even want to consider having multiple oil drains if oil changes are your primary service.

Smaller Oil Drains
You need to go with a small oil drain if your shop’s specialty is something besides oil changes (such as brakes and alignments). An 8-gallon or 18-gallon oil drain would be more suitable in this case. A small oil drain is a more affordable option for lower-volume repair shops, or even for DIYers at home.

The oil drain style you need
When determining whether you need a self-evacuating oil drain or a pump-assist oil drain, consider the following:

Self-evacuating oil drains use shop air to empty used oil and get the equipment back to the service floor. Capacities include 18, 25, and 27 gallons. An 18-gallon oil drain works well for shops who don’t do a ton of oil changes and have fewer bays, where shops who have an oil change focus with multiple bays would need drains that hold 25 or 27 gallons of oil. No auxiliary equipment—such as a diaphragm pump—is needed, so the initial investment of a self-evacuating oil drain is lower because you don’t have to add the expense of a diaphragm pump.

A pump-assist oil drain lets you hook up a suction hose directly to a full oil drain and transfer oil from the drain to the waste oil tank. Shop air usually runs the suction pump. Pump-assist oil drains can vary in size from 8 gallons for a smaller shop with a couple of bays to around 30 gallons for a high-volume operation with multiple bays. Shops already using a diaphragm pump can benefit the most from using a pump-assist oil drain to empty used oil, and then get back to work quickly. 

Determining if you need a steel or poly oil drain
Steel oil drains hold up well and can last a long time. But if you’re working on higher-end or specialty vehicles, you may want to consider a poly oil drain. If a technician bumps an expensive car with a steel oil drain, there could be damage left behind.

Our steel oil drains come in the following sizes: 16, 17, 18, 22, and 25 gallons.

If you are a lower-volume repair shop or a DIYer, an 8- or 18-gallon poly oil drain would be more suitable for your operation. If you are a bigger operation and want a poly oil drain, we offer them in the following additional sizes: 17, 22, and 27 gallons.

What is a pump-assist oil drain?

A pump-assist oil drain lets you hook up a suction hose directly to a full oil drain and transfer oil from the drain to the waste oil tank. Shop air usually runs the diaphragm suction pump.  

Pump-assist oil drains can vary in size from 8 gallons for a smaller shop with a couple of bays to around 30 gallons for a high-volume operation with multiple bays. Shops already using a diaphragm pump can benefit the most from using a pump-assist oil drain to empty used oil, and then get back to work quickly.

What is a self-evacuating oil drain?

Self-evacuating oil drains use shop air to empty used oil and get the equipment back to the service floor. Capacities include 18, 25, and 27 gallons. An 18-gallon oil drain works well for shops that don’t do a ton of oil changes and have fewer bays; whereas, shops that have an oil change focus with multiple bays would need drains that hold 25 or 27 gallons of oil.

With self-evacuating oil drains, no auxiliary equipment—such as a diaphragm pump—is needed. So, the initial investment of a self-evacuating oil drain is lower because you don’t have to add the expense of a diaphragm pump.

What is “auto check technology”? 

JDI’s Auto-Check Technology is exclusive to our self-evacuating oil drains. It utilizes a check ball in the bottom of the downtube to automatically seat up when shop air is hooked up to the drain. No one else’s drains work this way.

Auto-Check Technology eliminates the need for a large ball valve in the downtube. It also makes emptying the drain much easier for the shop technician. There’s no need to remember to close the ball valve when hooking up shop air. This avoids oil geysers that most shops have experienced at one time or another when using other self-evacuating oil drains.

How Do I Choose Between Steel or Poly Oil Drains?

Steel oil drains hold up well and can last a long time. But if you’re working on higher-end or specialty vehicles, you may want to consider a poly oil drain. If a technician bumps an expensive car with a steel oil drain, there could be damage left behind.

Our steel oil drains come in the following sizes: 16, 17, 18, 22, and 25 gallons.

If you are a lower-volume repair shop or a DIYer, an 8- or 18-gallon poly oil drain would be more suitable for your operation. If you are a bigger operation and want a poly oil drain, we offer them in the following additional sizes: 17, 22, and 27 gallons.

How do I determine the size oil drain I need? 

It depends. You’ll need to make your decision based on the way your business operates.

If oil changes are your main service, you need a large oil drain (20 gallons or more)—possibly several of them. If your specialty is in another area, you can get by with a smaller, 8- or 18-gallon oil drain.

Larger Oil Drains
You should invest in a large oil drain if changing oil is the main focus for your shop. A 25-gallon or 27-gallon oil drain would be ideal if you do a significant amount of oil changes on a typical day. You may even want to consider having multiple oil drains if oil changes are your primary service.

Smaller Oil Drains
You need to go with a small oil drain if your shop’s specialty is something besides oil changes (such as brakes and alignments). An 8-gallon or 18-gallon oil drain would be more suitable in this case. A small oil drain is a more affordable option for lower-volume repair shops, or even for DIYers at home.

EuroVent HVLS fans cover as low as 9,200 square feet with an 8-foot diameter 5-blade HVLS fan, up to 18,700 square feet with a 24-foot diameter 3-blade HVLS fan. 

How is HVLS performance measured and what should I look for?

Not all HVLS fans are created equal and are not the same. When it comes to performance, look for:

  • Maximum Cubic Feet per Minute (CFM)
  • Efficiency Cubic Feet per Minute per Watt (CFM/W)
  • coverage area in square feet
  • dBA at Maximum RPM (needs to be less than 85 dBA; the rate at which long or repeated exposure to sound can cause hearing loss)

Can HVLS fans come in different colors?

Yes with an additional charge. EuroVent’s HVLS fan blades come standard with a brushed aluminum finish. If you wanted a specific color, we do offer custom color match for an additional charge.

Is there a difference between a 3-blade and 5-blade HVLS fan?

Yes. More blades does not necessarily mean better performance. EuroVent’s 5-blade fan is ideal for small spaces with low- or medium-height ceilings, where EuroVent’s 3-blade fan is ideal for medium to large spaces with medium- to high-height ceilings.

EuroVent’s 5-blade HVLS fan has diameter options of 8’, 10’, 12’ or 14’ and creates air movement coverage up to 54,900 cubic feet per minute.

EuroVent’s 5-blade HVLS fan has diameter options of 16’, 18’, 20’ or 24’ and creates air movement coverage up to 164,900 cubic feet per minute.

What other ceiling fan requirements are there?

In addition to DOE Efficiency legislation, HVLS fans must be in accordance to Fire code – nfpa 13. This code includes:

  • Maximum fan diameter shall be 24 ft.
  • Fan shall be centered between 4 sprinklers
  • Vertical clearance to sprinkler deflector shall be minimum of 3 ft.
  • Fans shall be interlocked to shut down upon receiving fire alarms

HVLS fans must also me in accordance of ASHRAE 55 – Comfort Cooling. ASHRAE 55 establishes methodology for quantifying the effect of air velocity on thermal comfort

What is a direct drive fan? What is a conventional (or gearbox-driven) motor? And what is the difference?

A direct drive fan is a smaller, quieter, more efficient motor compared to a gearbox-driven motor. With a gearbox-driven fan, the motor provides powers the gearbox, which in turn powers the blades to turn. A direct drive uses a motor to power the blades, eliminating the need and issues related to a gearbox. 

Are there efficiency standards for ceiling fans?

Yes. The Department of Energy (DOE) sets standards for efficiency in ceiling fans by measuring cubif feet per minute per watt (CFM/W) used to power the fan. 

All EuroVent HVLS fans cover nearly twice the DOE’s minimum standard of CF/W.

How do HVLS fans save energy?

Using low speeds, HVLS fans use a fraction of the energy of conventional fans while providing a comfortable indoor breeze. The 3-5 mph breeze generated by a EuroVent HVLS fan creates a cooling sensation by as much as 10°F, supplementing air conditioning systems for a higher thermostat setting. 

With destratification, an HVLS fan creates a more uniform and comfortable temperature, further allowing thermostat settings to maintain for longer periods of time.

Direct drive motors in HVLS fans use 20% less energy than gearbox-driven motors. 

EuroVent HVLS fans generate up to 30 percent more airflow and only need half the amount of horsepower compared to other HVLS fans.

What is destratification?

Destratification is the process of mixing the rising warmer air trapped at the ceiling with the colder air at  the floor level. This creates a more uniform and comfortable temperature from floor to ceiling. It also allows for thermostat settings to maintain for longer periods of time to reduce energy costs.

How fast are HVLS fans?

EuroVent HVLS fans generally range in speed of 3-5 mph.

How big are HVLS fans?

EuroVent HVLS fans can range in size from 8 feet up to 24 feet in diameter.

Why would I need an HVLS fan?

It is always wise to have great air circulation, especially when operating a larger facility.  Facilities that benefit from HVLS fans the most are:

– Office spaces
– Restaurants and bars
– Education facilities
– Supermarkets
– Retail stores
– Fitness centers
– Airports
– Gyms
– Agricultural facilities
– Manufacturing facilities
– Automotive facilities
– Distribution Centers
– Stadiums & Arenas

What is an HVLS Fan?

Can I alter a fuel caddy?

No. You should never alter a fuel caddy other than adding an approved fuel pump. Altering a gas caddy will void any warranty and governing body approval (UL Listed and UN/DOT approval).

Can I get a pump for a fuel caddy?

Yes. We offer rotary hand pumps and pump kits for steel and poly fuel caddies.

How does the fuel in a poly fuel caddy flow?

A poly fuel caddy uses gravity to dispense the fuel from the caddy to the tank you are filling. In most cases, you can purchase an optional rotary pump kit to empty the fuel from the caddy to the tank you are filling.

How big are fuel caddies?

Our steel fuel caddies come in two sizes. We offer 25-gallon and 30-gallon fuel caddies for both gasoline and diesel.

Our poly fuel caddies also come in two sizes. We offer 15- and 25-gallon gasoline caddies in red, and a 25-gallon diesel caddy in yellow.

Do I need a plastic or steel fuel caddy? 

If you are temporarily storing fuel to be put back in a vehicle, a U.L. listed steel caddy is the way to go. If you are transporting fuel over the road, a UN/DOT approved plastic fuel caddy is what you will need.

Can I put gas in my diesel caddy or vice versa?

To avoid mixing and contamination, a caddy needs to be dedicated to a specific type of fuel. Any container used to store gas or diesel must be properly marked with the stored fuel. Generally, gas is kept in a red caddy, and diesel is stored in a yellow caddy. This allows technicians to easily identify each fluid in the shop.

Simply put, you should not put gas in a diesel caddy because you’d create a safety hazard. Improper storage of flammable and combustible liquids such as diesel and gas can lead to fires or explosions. Storing gas in a gas-designated caddy that is U.L. listed and meets Occupational Safety and Health Administration (OSHA) standards is the best way to ensure safety.

What is the difference between a gas caddy and a diesel caddy?

If your shop deals with gasoline and diesel, you must have the appropriate containers. You cannot store gasoline in a diesel caddy or vice versa. To avoid mixing and contamination, you need to dedicate each caddy to a specific type of fuel. Generally red fuel caddies are designated for gasoline, and yellow fuel caddies are designated for diesel. This allows technicians to easily identify each fluid in the shop and not waste time trying to figure out which is gasoline and which is diesel.

Improper storage of flammable and combustible liquids can lead to serious fires or explosions. You must properly mark the type of stored fuel on any container used to store gasoline or diesel.

What’s the major difference between U.L. Listed fuel caddies and UN/DOT approved fuel caddies?

If the need is to temporarily store fuel like in a shop setting, like when replacing a fuel pump, you’ll need a U.L. listed fuel caddy. If the need is to transport fuel over the road, like going on a weekend ATV trip, you’ll need a UN/DOT container.

What kinds of fuel caddies are available?

There are two main types of fuel containers: U.L. listed steel fuel caddies and UN/DOT-approved poly fuel caddies. U.L. listed steel fuel caddies provide temporarily fuel storage in a professional repair facility. UN/DOT-approved poly fuel caddies are for transporting fuel on public roads.

Do I need a UL Listed fuel caddy? 

You need a U.L. listed steel fuel caddy when you’re going to temporarily store fuel in your work environment. If you’re working on a vehicle fuel system, you need a product that’s been tested rigorously and will hold up in a shop setting. Otherwise, you’re dealing with a major fire hazard.

A U.L. listed fuel caddy’s features include flame arresters on the openings, grounding cables, non-sparking foot plates, and fill gauges. This type of fuel caddy will pass Occupational Safety and Health Administration (OSHA) and fire marshal inspections.

Do I need a UN/DOT approved fuel caddy? 

You should use a UN/DOT-approved poly fuel caddy when you’re going to transport fuel on public roads. The label means the fuel caddy was approved by the United Nations (UN) and the U.S. Department of Transportation (DOT). This packaging is a universal means of ensuring safe transport of dangerous materials.

When you’re transporting more than five gallons of fuel, most municipalities require a UN/DOT-approved container. If you don’t have the right gas caddy, you could find yourself in trouble with local law enforcement. You also get peace of mind that your container can safely transfer fuel.
