-139 BLACK FKM 90D O-RING

Part number V90139 is an AS568-139 black Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 2.175 in (55.25 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.381 in (60.48 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to engine and transmission fluids, petroleum oils and fuels, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is specified for outstanding high-temperature capability and long service life in hot, chemically aggressive environments. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with amines or hot water and steam.

Common environments for this compound include automotive fuel systems, high-temperature process equipment, and aerospace.

Stocked as V90139 and sold individually. Unit weight is approximately 1.8206 g and nominal inside diameter is listed as 2 3/16 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
