Viton® (FKM) delivers excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Expect good resistance to many acids, chlorinated solvents, and petroleum oils and fuels. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in low-molecular-weight organic acids or hot water and steam.

You will find this material specified across oil and gas, high-temperature process equipment, and automotive fuel systems.

QV70048 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
