-474 BLACK CHEMOURS VITON 75D O-RING

Part number VITON75474 is an AS568-474 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 24.94 in (633.48 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 25.49 in (647.45 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Viton® (FKM) is valued for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. The material holds up against engine and transmission fluids, petroleum oils and fuels, and aromatic hydrocarbons. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to low-molecular-weight organic acids or amines will shorten service life.

Maintenance and OEM teams specify it across aerospace, chemical processing, and automotive fuel systems.
