-442 BLACK FKM 75D O-RING

APG stocks the V70442, an AS568-442 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 7.225 in (183.52 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 7.775 in (197.49 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against aggressive chemicals, many acids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) delivers very low compression set at elevated temperature, excellent resistance to compression set and permeation. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Applications involving hot water and steam or ketones and esters call for a different compound.

Common environments for this compound include high-temperature process equipment, aerospace, and oil and gas.

V70442 ships individually. Unit weight is approximately 42.053 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
