-157 BLACK FKM 90D O-RING

V90157 is an AS568-157 black Viton® (FKM) 90 Shore A O-Ring with an inside diameter of 4.487 in (113.97 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 4.693 in (119.2 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. It resists chlorinated solvents, aromatic hydrocarbons, and aggressive chemicals. 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 high-temperature process equipment, aerospace, and semiconductor equipment.
