This o-ring is supplied in AS568-351 black Viton® (FKM) 75 Shore A supplied with an inside diameter of 4.725 in (120.02 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.145 in (130.68 mm), catalogued under part number V75351. It delivers dependable bidirectional sealing in a compact groove envelope.

This material stands up to engine and transmission fluids, petroleum oils and fuels, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

Typical settings include semiconductor equipment, aerospace, and high-temperature process equipment.

This item is sold individually under part number V75351. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
