An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to chlorinated solvents, engine and transmission fluids, and petroleum oils and fuels. Viton® (FKM) offers very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving amines or hot water and steam call for a different compound.

It sees regular use in chemical processing, aerospace, and high-temperature process equipment.
