Viton® (FKM) is specified here for industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. The compound resists petroleum oils and fuels, chlorinated solvents, and aggressive chemicals. The material carries a published service range of -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.
