Viton® (FKM) delivers long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Expect good resistance to engine and transmission fluids, aromatic hydrocarbons, and many acids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to amines or ketones and esters will shorten service life.

Maintenance and OEM teams specify it across oil and gas, chemical processing, and high-temperature process equipment.
