-374 BLACK FKM 75D O-RING

APG stocks the V75374, an AS568-374 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 9.225 in (234.32 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 9.645 in (244.98 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to chlorinated solvents, engine and transmission fluids, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) offers excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).

It sees regular use in automotive fuel systems, semiconductor equipment, and aerospace.

V75374 ships individually. Nominal inside diameter is listed as 9 1/4 inch. 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.
