Expect good resistance to many acids, chlorinated solvents, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) offers excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with hot water and steam or ketones and esters.

The compound meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Typical settings include automotive fuel systems, high-temperature process equipment, and chemical processing.
