1.6MM CS X 21.1MM ID BLACK FKM 75D

This o-ring is supplied in black Viton® (FKM) 75 Shore A with an inside diameter of 21.1 mm (0.831 in), a cross section of 1.6 mm (0.063 in), and an outside diameter of 24.3 mm (0.96 in), catalogued under part number V1.6X21.1. It remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against chlorinated solvents, aggressive chemicals, and many acids. Viton® (FKM) offers long service life in hot, chemically aggressive environments 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). Exposure to amines or hot water and steam will shorten service life.

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