HYDROGEN GAS Resistant O-Rings and Seals
Hydrogen gas (H2) is an odorless, colorless gas that is often used as a fuel source in a variety of industries, such as aerospace and automotive. Common uses for hydrogen gas include fuel cells, rocket propulsion, and hydrogen fuel production.
Common types of failures when rubber is exposed to hydrogen gas include discoloration, cracking, and embrittlement due to the extreme temperatures hydrogen gas can reach when burned. Additionally, rubber seals exposed to hydrogen gas may become brittle and prone to cracking or tearing over time due to the extreme temperatures the gas can reach when burned. Additionally, exposure to hydrogen gas may cause the rubber seal to swell or become distorted due to the extreme temperatures it can reach when burned.
