FAQ

What is the difference between FKM and FPM?

FKM is the international material designation, while FPM is the equivalent designation commonly used in European standards. Both refer to fluorocarbon rubber.

Is Viton the same as FKM?

Viton® is a registered trade name for specific fluorocarbon elastomer compounds manufactured by Chemours. FKM is the generic material designation.

Is the O-ring resistant to fuels?

Yes. FKM provides excellent resistance to gasoline, diesel fuel, mineral oils and many industrial chemicals.

What operating temperatures can it withstand?

Typical operating temperatures range from approximately -20°C to +200°C, with short-term exposure up to approximately +230°C.

When should FKM be selected instead of NBR?

FKM is preferred for applications involving high temperatures, aggressive chemicals, fuels and synthetic oils, while NBR is often a more economical choice for standard oil sealing applications.
