HELIUM Resistant O-Rings and Seals
Helium is a noble gas and is not commonly used in industries. It has no common names. Helium is mainly used for its low boiling point, which makes it useful for cryogenics and to pressurize liquid-fueled rockets. When rubber is exposed to helium, it can cause the rubber to become brittle and crack due to the cold temperatures. Additionally, because helium is a non-polar atom, it may not form strong bonds with rubber molecules, leading to further degradation and failure of the rubber material.
