-283 BLACK CHEMOURS VITON 75D O-RING

Part number VITON75283 is an AS568-283 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 16.955 in (430.66 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 17.233 in (437.72 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The material holds up against petroleum oils and fuels, engine and transmission fluids, and aggressive chemicals. Viton® (FKM) is widely chosen for 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). It is not the right choice where hot water and steam or low-molecular-weight organic acids are present.

Maintenance and OEM teams specify it across high-temperature process equipment, automotive fuel systems, and semiconductor equipment.
