-157 BLACK FKM 75D O-RING

APG stocks the V75157, an AS568-157 black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 4.487 in (113.97 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 4.693 in (119.2 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists engine and transmission fluids, aggressive chemicals, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is known for long service life in hot, chemically aggressive environments and outstanding high-temperature capability. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).

You will find this material specified across automotive fuel systems, semiconductor equipment, and high-temperature process equipment.
