The compound resists chlorinated solvents, many acids, and aggressive chemicals. Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or amines will shorten service life.

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