-381 BLACK FKM 75D O-RING

APG stocks the V70381, an AS568-381 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 11.975 in (304.17 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 12.395 in (314.83 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists chlorinated solvents, aggressive chemicals, and aromatic hydrocarbons. Viton® (FKM) is specified for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where hot water and steam or amines are present.

You will find this material specified across semiconductor equipment, chemical processing, and oil and gas.

V70381 ships individually. Unit weight is approximately 40.38 g and nominal inside diameter is listed as 12 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
