3MM CS X 250MM ID BLACK FKM 75D

This o-ring is supplied in black Viton® (FKM) 75 Shore A measuring an inside diameter of 250 mm (9.843 in), a cross section of 3 mm (0.118 in), and an outside diameter of 256 mm (10.08 in), catalogued under part number V3X250. It compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to petroleum oils and fuels, aggressive chemicals, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or amines.

It sees regular use in chemical processing, high-temperature process equipment, and automotive fuel systems.

V3X250 ships individually. Unit weight is approximately 10.545 g. Review your operating media and conditions against this specification before installation. 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.
