Expect good resistance to chlorinated solvents, many acids, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) delivers very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or low-molecular-weight organic acids will shorten service life.

Maintenance and OEM teams specify it across automotive fuel systems, high-temperature process equipment, and oil and gas.
