Developed specifically for the chemical process industry, our FFKM O-rings deliver outstanding performance across the widest possible range of chemicals and temperatures — an excellent choice for acids, bases, amines, steam and ethylene oxide.
FFKM is the top of the elastomer ladder: nearly all carbon–hydrogen bonds are replaced by carbon–fluorine, giving chemical resistance close to PTFE while the part still seals like a rubber. It is specified when two or more severe conditions act together.
Key Features
- Temperature: −10 to 280 °C
