Part number V70145 is an AS568-145 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 2.55 in (64.77 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.756 in (70 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.
The material holds up against petroleum oils and fuels, aromatic hydrocarbons, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) offers very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where amines or hot water and steam are present.
Common environments for this compound include oil and gas, high-temperature process equipment, and automotive fuel systems.
Stocked as V70145 and sold individually. Unit weight is approximately 2.114 g and nominal inside diameter is listed as 2 9/16 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. 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.
