Gas cans are an essential tool for a lot of different applications, from fueling your lawn mower and other equipment to powering generators and ATV's. However, users often encounter issues like bloating in high temperatures and collapsing in colder environments. These problems not only hinder performance but can also pose safety risks. At SureCan, we are always trying to find ways to make things better and easier to use. Our latest innovation is the Replacement Fill Cap Lid with Duckbill Valve is solving gas can bloating and collapsing problems. It offers a solution to these common challenges and allows your SureCan gas can to breathe in and out during these temperature swings. This means no more bloating in heat and collapsing in the cold.
Why Do Gas Cans Expand and Collapse?
There is actually a science behind it. It's called the Combined Gas Law and is a pretty basic concept that does makes sense when explained. Yet, for decades, users have struggled with this problem, especially with newer EPA and CARB gas cans that cannot vent on their own. EPA and CARB Regulations mandate that a gas can cannot vent on its own and must be sealed while not in use to prevent vapor from escaping into the air. While OSHA Safety Can Regulations mandate that a gas can must vent on its own to relieve internal pressure.
This scientific principle explains the relationship between pressure, volume, and temperature in a sealed container. When a gas can is left in the sun, the rising temperature causes the air and vapors inside to expand. Because the container is sealed, this expansion increases internal pressure, leading to bloating or bulging of the gas can’s walls. Conversely, in colder conditions, the internal vapors contract, lowering internal pressure. This drop in pressure can create a vacuum effect that causes the can to cave in on itself, a phenomenon commonly referred to as gas can collapse. These pressure fluctuations are not only inconvenient but can compromise the structural integrity of the can and create potential issues.
The SureCan Solution. OSHA Gas Can Certified + Fill Cap Lid with Duckbill Valve Solving Gas Can Bloating and Collapsing Problems
We have recognized the combined gas law exists in gas cans and is a pain point for consumers like you. That is why we have taken extra steps over the years to improve SureCan and make it better. This includes redesigning our cap system and getting SureCan certified and approved for OSHA standards, making it a Safety Can. For extra measure we have recently added a Duckbill Valve to our gas cans fill caps. This ensures that your SureCan will breathe better allowing the air to escape preventing it from bloating and collapsing.
Unlike all of the other gas can lids that are completely sealed, this valve allows your SureCan to "breathe." When pressure builds up in warm weather, the valve opens slightly to release air and fuel vapors, thus avoiding expansion and collapse. In cold conditions, when internal pressure drops, the valve allows air to re-enter, preventing a vacuum from forming and averting collapse. This ensures the gas can maintain its shape and usability, regardless of temperature fluctuations.
Quick and Easy Installation
Installing the Fill Cap Lid with Duckbill Valve is quick and simple. Users only need to remove their existing fill cap lid, place the washer around the ball joint on the new cap lid and secure it by pressing down until it fits snugly. Once installed, the duckbill valve works automatically, no additional action or manual venting is required by the user. To maintain optimal functionality, we recommends periodically checking the valve for debris or damage and cleaning it gently.
