-163 BLACK FKM 75D O-RING

Part number V70163 is an AS568-163 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 5.987 in (152.07 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 6.193 in (157.3 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to petroleum oils and fuels, chlorinated solvents, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is valued for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

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

Order part number V70163, sold individually. Unit weight is approximately 4.845 g and nominal inside diameter is listed as 6 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. 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.
