The V3X31.2 is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 31.2 mm (1.228 in), a cross section of 3 mm (0.118 in), and an outside diameter of 37.2 mm (1.46 in). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
This material stands up to chlorinated solvents, petroleum oils and fuels, and engine and transmission fluids. Viton® (FKM) delivers excellent resistance to compression set and permeation, outstanding high-temperature capability. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or hot water and steam will shorten service life.
Common environments for this compound include high-temperature process equipment, chemical processing, and oil and gas.
Stocked as V3X31.2 and sold individually. Unit weight is approximately 1.4 g. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
