Buyer's Guide

It only takes one time to run out of gas and become stuck on the side of the road in a remote part of the country to realize the value of a gas can. A gas can is practically necessary if you frequently take road trips. Aside from when you need gas in a pinch, you might find it useful to fill up your lawnmower or other gas-powered garden equipment. Apart from choosing a gas can that meets your demands, you must also learn how to properly store the fuel so that it does not become polluted or create a potential environmental or physical hazard. A gas can cap comes in handy in this scenario.

What are the advantages of using a gas can cap?

A gas can cap is primarily useful for secure gasoline storage. This has a ton of perks. It minimizes spilling and evaporating gasoline, for starters. You don't want to waste your money on gas, especially with how expensive it has gotten recently. It's also bad for the environment, and we should all do our share to safeguard the beauty of nature.

We certainly cannot overlook the reality that gas leaks might be quite hazardous. Fuel is very flammable, and spilling it near heat sources may potentially lead to dire consequences.

All in all, different kinds of gas caps provide different features that you might need for a specific piece of equipment.

What are the factors to consider when buying a gas can cap?

Frequency of use

The frequency with which you use your gas can is a consideration to consider before ordering a cap. If you intend on using it frequently, you can avoid the lower-cost gas can caps and instead go for the more resilient and high-quality alternatives on the market.


When searching for a substitute cap for a gas can, see whether the spout cap has to be replaced as well. You'll also need something with the right diameter and mounting style, so make sure the new spout kit fits your gas can.

The density of the material

Another factor to consider is the thickness of the material used in the cap's fabrication. Since plastic is non-toxic and generally non-reactive, it is frequently used to make both gas cans and caps. Not all plastics are equal, though - look for options that utilize thicker plastic, as they will be more robust and are better able to withstand pressure and temperature changes.

What is the best way to clean a gas can?

This may sound like a cop-out, but we recommend against washing gas cans at home. While gasoline is a very commonly encountered substance, disposal of gasoline is very tightly controlled and must only be done under specific circumstances. Not only is it dangerous to improperly dispose of gas, but it's also a possible violation of multiple state and federal laws, not to mention municipal codes.

If you feel that your gas can has become too old and contaminated, it's best to drop it off at a designated disposal location and purchase a new can instead.

Gas Can Cap FAQ

Q: Is driving with a gasoline can in your car completely safe?

A: It's usually not regarded as safe since a minor leakage in the gas or nozzle may allow fumes to build up in your vehicle. If these fumes get beyond a certain concentration, this may pose a fire hazard. Thus, it is best to skip traveling with a full gas can in your car whenever possible.

Q: How adaptable are gas can caps?

A: Most gas can caps are designed to fit on the majority of gas cans sold today, including the most commonly encountered spout sizes. As always, there are exceptions, so it's best to do your homework before blindly purchasing a replacement cap.
