O ring 9x2.2 FKM FPM Viton seal

Application in demanding industrial environments

O ring 9x2.2 FKM FPM Viton is a high performance elastomer sealing solution designed for use in applications exposed to elevated temperatures, oils, fuels and aggressive chemicals. Within the FKM FPM O ring category, this size is widely selected for compact assemblies requiring reliable static or dynamic sealing.

The 9x2.2 mm O ring is commonly used in hydraulic systems, fuel systems, pumps, valves and industrial machinery components. Thanks to the chemical resistance of FKM FPM Viton, it performs reliably in environments where standard NBR seals may degrade prematurely. It is suitable for both maintenance operations and original equipment manufacturing.

Material properties and sealing performance

The FKM FPM compound, often referred to as Viton, offers excellent resistance to mineral oils, synthetic lubricants, fuels and many chemical agents. It maintains mechanical stability under elevated operating temperatures and shows strong resistance to aging and compression set.

With a standard hardness of 70 Shore A, the O ring provides a balanced combination of elasticity and dimensional stability. The precision molded cross section of 2.2 mm ensures consistent contact pressure when installed in properly designed grooves according to standard O ring sealing practices.
