Perfluorocarbon (FFKM) O-rings

Parco’s perfluoroelastomer (FFKM) O-rings provide an alternative to those made from Kalrez® and similar perfluoroelastomers. FFKM O-rings can be used in continuous temperatures of up to 600°F and resist more chemicals than seals made from other elastomers.

Individual FFKM compounds have service temperatures that range from 10 to +600°F. Parco’s most popular high performance FFKM compound for O-rings is listed below.
