-168 BLACK FKM 75D O-RING

APG stocks the V75168, an AS568-168 black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 7.237 in (183.82 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.443 in (189.05 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists engine and transmission fluids, aggressive chemicals, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is valued for excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or hot water and steam will shorten service life.

Maintenance and OEM teams specify it across aerospace, oil and gas, and chemical processing.

Stocked as V75168 and sold individually. Nominal inside diameter is listed as 7 1/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
