Perfluoroelastomer O Rings (FFKM)

Perfluoroelastomer FFKM O Rings Supplier UK

The UK’s largest Perfluoroelastomer / FFKM O Rings provider – available from stock. Our O Rings offer outstanding performance in demanding operating environments. The chemical and heat resistance of Perfluoroelastomer (FFKM) are similar to those of PTFE. It combines the positive properties of a PTFE O Ring with the elastic behaviour of FKM / Viton O Ring. Perfluoroelastomer / FFKM O Rings are only used if other materials cannot meet the very high application specifications.

Typical applications for FFKM O Rings include the Chemical, Aerospace, Oil, High Vacuum Technology and Semi-conductor industries.
