Can rubber gaskets be used in gas piping flanges?

Rubber gaskets are generally not suitable for use in gas piping flanges due to their potential to degrade when exposed to hydrocarbons and other chemicals present in gas. Gas systems require gaskets that can withstand various pressures and temperatures without compromising the integrity of the seal. Materials typically used for gas applications include metals, fiber, or specific synthetic materials that have proven compatibility with gas and a capacity to maintain their properties under the conditions present in gas piping systems.

Using rubber gaskets can lead to leakage, which poses serious safety hazards, including risk of fire or explosion. Therefore, opting for approved materials helps ensure both safety and compliance with industry standards and regulations. This reinforces the idea that only specific materials should be considered safe for gas piping applications.
