Material Properties

FPM (FKM, Viton) fluoroelastomer provides outstanding resistance to mineral oils, synthetic lubricants, fuels, aromatic and aliphatic hydrocarbons, ozone and many aggressive industrial chemicals. The material also offers excellent ageing resistance, very low gas permeability and superior thermal stability, making it suitable for demanding industrial environments. Typical operating temperatures range from approximately -20 C to +200 C, with some compounds capable of short-term exposure up to +220 C. These properties make FPM one of the preferred sealing materials for hydraulic, chemical and high-performance industrial systems.

FAQ

What is the difference between FPM and FKM?

FPM and FKM refer to the same fluoroelastomer material. FPM is the DIN/ISO designation, while FKM is the ASTM designation.

Is this O-ring suitable for hydraulic oil?

Yes. FPM provides excellent resistance to most mineral and synthetic hydraulic oils used in industrial applications.

Can this O-ring be used in chemical processing equipment?

Yes. FPM offers excellent compatibility with many aggressive chemicals, solvents and hydrocarbons commonly used in industrial processing.

Why choose FPM instead of NBR?

FPM provides significantly higher temperature capability, improved chemical resistance and longer service life in demanding industrial environments.

Is the 100x3.55 size manufactured according to international standards?

Yes. This metric O-ring size complies with internationally recognized standards such as DIN 3771 and ISO 3601.
