FFKM O-Rings are manufactured from perfluoroelastomer (FFKM), offering the highest level of chemical resistance and thermal stability among elastomer sealing materials.
They provide near-universal chemical compatibility and are designed for extreme operating environments where other elastomer fail.
FFKM O-Rings are suitable for static sealing and dynamic sealing under high temperature and aggressive chemical exposure.
