-433 BLACK CHEMOURS VITON 75D O-RING

Part number VITON75433 is an AS568-433 black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 5.475 in (139.07 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 6.025 in (153.04 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists many acids, engine and transmission fluids, and chlorinated solvents. Viton® (FKM) is known 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). Exposure to hot water and steam or low-molecular-weight organic acids will shorten service life.

Common environments for this compound include high-temperature process equipment, chemical processing, and oil and gas.
