It resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

As a material, Viton® (FKM) is valued for outstanding high-temperature capability, excellent resistance to compression set and permeation. The material holds up against chlorinated solvents, petroleum oils and fuels, and engine and transmission fluids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or hot water and steam are present.
