Viton™ O Rings and FKM O Ring materials have very high resistance to temperatures and chemicals. This makes them ideal for industries such as Agricultural, AutomotiveAerospace and DefencePetrochemical, Offshore Drilling, and Rail.

Other key benefits are its excellent resistance to ageing and ozone, very low gas permeability (excellent for vacuum application) and the fact that it is self-extinguishing. Temperature resistance range can be from -20°C to +205°C (or intermittent between -45°C and +230°C).
