3MM CS X 68MM ID BLACK FKM 75D

Part number V3X68 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 68 mm (2.677 in), a cross section of 3 mm (0.118 in), and an outside diameter of 74 mm (2.91 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to petroleum oils and fuels, engine and transmission fluids, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is known for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C).

Common environments for this compound include semiconductor equipment, aerospace, and chemical processing.

Stocked as V3X68 and sold individually. Unit weight is approximately 2.9528 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. 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.
