1.5MM CS X 50MM ID BLACK FKM 75D

Ordered as V1.5X50, this is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 50 mm (1.969 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 53 mm (2.09 in). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists aromatic hydrocarbons, engine and transmission fluids, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is valued for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with amines or low-molecular-weight organic acids.

You will find this material specified across aerospace, automotive fuel systems, and high-temperature process equipment.
