-340 BLACK FKM 90D O-RING

Part number V90340 is an AS568-340 black Viton® (FKM) 90 Shore A O-Ring measuring an inside diameter of 3.35 in (85.09 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.77 in (95.76 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Viton® (FKM) is specified for long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. The material holds up against chlorinated solvents, many acids, and engine and transmission fluids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.

It sees regular use in automotive fuel systems, high-temperature process equipment, and oil and gas.
