HYDROGEN SULFIDE, WET HOT Chemical compatibility with O-rings, rubbers, & plastics

Hydrogen sulfide, commonly known as H2S or sour gas, is a colorless, highly toxic gas with a distinctive rotten egg odor frequently encountered in petroleum refining, geothermal energy production, and metal processing. In wet, hot environments, the combination of moisture and elevated temperatures can increase corrosion and accelerate material degradation. When reviewing chemical compatibility, O-rings, rubber seals, gaskets, and plastic components must be carefully selected for resistance to hydrogen sulfide exposure. Proper ventilation, gas detection systems, safe handling procedures, and protective equipment are essential to reduce risk.
