-309 BLACK CHEMOURS VITON 75D O-RING

Part number VITON75309 is an AS568-309 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 0.412 in (10.46 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 0.832 in (21.13 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists engine and transmission fluids, many acids, and aggressive chemicals. Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in hot water and steam or low-molecular-weight organic acids.

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