-143 BLACK FKM 75D O-RING

The V75143 is an AS568-143 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 2.425 in (61.6 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.631 in (66.83 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to aromatic hydrocarbons, chlorinated solvents, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) delivers outstanding high-temperature capability, excellent resistance to compression set and permeation. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).

Common environments for this compound include high-temperature process equipment, chemical processing, and automotive fuel systems.

Order part number V75143, sold individually. Nominal inside diameter is listed as 2 7/16 inch. Check the compound against your process media, pressure and temperature before committing to a design. 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.
