-425 BLACK CHEMOURS VITON 75D O-RING

Part number VITON75425 is an AS568-425 black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 4.475 in (113.67 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.025 in (127.64 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Viton® (FKM) is specified here for industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. The compound resists petroleum oils and fuels, engine and transmission fluids, and chlorinated solvents. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.

Maintenance and OEM teams specify it across chemical processing, semiconductor equipment, and aerospace.
