Flex Seal is a popular sealant and adhesive marketed for its ability to repair leaks and seal various surfaces. However, there is some debate about whether Flex Seal can be used to stop gas leaks. This article will examine the properties of Flex Seal and its suitability for use on gasoline tanks, citing relevant sources to support the discussion.
Key Facts
- Flex Seal is not designed to withstand heat or pressure, and it is not recommended for use with flammable liquids like gasoline.
- The manufacturer’s website states that Flex Seal is not a good choice for sealing gasoline tanks.
- Flex Seal is primarily marketed as a product for sealing leaks in roofs, gutters, pipes, and other non-gasoline-related applications.
Properties of Flex Seal
Flex Seal is a liquid rubber sealant that cures into a flexible, waterproof coating. It is designed to be applied to a variety of surfaces, including metal, plastic, and concrete. Flex Seal is often used to repair leaks in roofs, gutters, pipes, and other structures.
Suitability of Flex Seal for Gasoline Tanks
Despite its versatility, Flex Seal is not recommended for use on gasoline tanks. There are several reasons for this:
- Heat and Pressure Resistance: Flex Seal is not designed to withstand the heat and pressure generated by gasoline. Gasoline is a flammable liquid that can reach high temperatures when ignited. The pressure inside a gasoline tank can also be significant, especially when the tank is full. Flex Seal may not be able to withstand these conditions and could fail, leading to a leak.
- Manufacturer’s Recommendations: The manufacturer of Flex Seal explicitly states that the product is not intended for use on gasoline tanks. This warning is included on the product label and in the product’s safety data sheet.
- Intended Use: Flex Seal is primarily marketed as a product for sealing leaks in roofs, gutters, pipes, and other non-gasoline-related applications. The product is not specifically designed or tested for use on gasoline tanks.
Conclusion
Based on the available evidence, it is clear that Flex Seal is not a suitable product for sealing gasoline leaks. The product is not designed to withstand the heat and pressure associated with gasoline, and the manufacturer specifically warns against using it on gasoline tanks. Therefore, it is strongly advised against using Flex Seal to repair gasoline leaks.
