FFKM O-rings are exceptionally resistant to degradation by aggressive fluids and gases. FFKM also has excellent resistance to extreme temperatures (-10°C to +260°C). Some special FFKM compounds can operate beyond 300°C.
The chemical and heat resistance of FFKM is similar to PTFE. It combines the positive properties of a PTFE O-ring with the elastic behaviour of an FKM O-ring.
FFKM O-rings offer resistance to almost all chemicals. These include inorganic acids, alkalines, ketones, esters, alcohols, fuels and hot water. They can also be used for applications in aggressive chemical environments. Typical applications for FFKM O-rings include Chemical, Aerospace, Oil, High Vacuum Technology and Semi-conductor industries.
Our Standard FFKM O-rings provide outstanding heat resistance with service temperatures of -10°C to 310°C.
Eastern Seals offer direct FFKM equivalents to Kalrez® Simrez® Perlast® Chemraz® grades. Please contact us to order FFKM O-Rings, or to find out more information.
