If you have ever gone through the tedious and laborious activity of dispensing fuel from your gas can, then you must have encountered that rigorous splash as the liquid sprouts out of the can. That is about to change. In the U.S., gas cans and containers came with two vents, previously. Now, they only come with one opening for pouring and filling. There’s a need for a sufficient pressure difference for a steady and continuous flow of fuel out of your can. A gas can vent provides that pressure difference. And just like every dog needs a home, every vent also needs a cap. After some thorough investigation, the options below are guilty of being the best gas can vent caps in 2023. We have also done our research to provide you with all the information you need to buy one.
When you pour out of a regular can, you experience some resistance which only happens because as you pour out of the spout, there is a pressure build-up due to the trapped air in the can. If you pour too quickly, you will end up splashing fuel all around and making a big mess. The better option is creating vents by simply puncturing a second hole at the other upper end of your gas can. So now that you have a hole, how do you seal it?
Gas can vent caps, like a rain cap provide a means to dispense fuel, water, and other liquids quickly and smoothly. They sure save you time and effort. We know there are way more options for gas vent caps as there are B films on Netflix. So we thought that you might want to know what you’re buying and how it works to make the right purchase.
What gives a vent gas cap its mysterious abilities is air pressure. When you pour out of a gas can through the spout, the air around you is constantly trying to get in through that opening of gas vents. And like a truck trying to take a one-way, there is some fluid traffic. This traffic is reflected in the inconsistent flow you notice as the liquid is pouring out. Pressure continues to build inside the can as the air continuously gets trapped. If you pour too quickly, the gasoline will splash out uncontrollably out of vent pipe.
Just like all water heaters that burn natural gas or liquid propane gas require a venting system, a gas vent creates an equal and opposite pressure that balances out the air pressure pushing in from the spout. This allows a steady flow of gasoline even when you pour out quickly.
