SULFUR HEXAFLUORIDE Resistant O-Rings and Seals
Sulfur hexafluoride is also known as sulfur fluoride, sulfur tetrafluoride, octofluoride and sulfonitride. It is used in a variety of applications including in electrical equipment, in magnesium smelting and as a tracer gas.
When rubber is exposed to sulfur hexafluoride, the rubber can become brittle and may suffer from accelerated aging. In some cases, the rubber can even become hard and may crack. Additionally, the rubber can become discolored and may not be able to maintain its flexibility.
EPDM (EP, EPR, Ethylene-Propylene Rubber)
EPDM o-rings, or ethylene propylene o-rings, are a family of synthetic elastomers with lower cost steam and chemical resistance, particularly for applications involving solvents, acids and other mild chemicals. Marco Rubber has the world’s largest inventory network of EPDM o-rings and made on demand custom manufacturing often without tooling fees, so the EPDM o-rings you need are always available.
