Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. The material holds up against aggressive chemicals, chlorinated solvents, and petroleum oils and fuels. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to ketones and esters or amines will shorten service life.

It sees regular use in aerospace, chemical processing, and semiconductor equipment.
