3MM CS X 87MM ID BLACK FKM 75D

The V3X87 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 87 mm (3.425 in), a cross section of 3 mm (0.118 in), and an outside diameter of 93 mm (3.66 in). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against engine and transmission fluids, chlorinated solvents, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).

Typical settings include automotive fuel systems, semiconductor equipment, and chemical processing.
