3MM CS X 245MM ID BLACK FKM 75D

V3X245 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 245 mm (9.646 in), a cross section of 3 mm (0.118 in), and an outside diameter of 251 mm (9.88 in). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments and industry benchmark where nitrile reaches its thermal limit. Expect good resistance to aggressive chemicals, engine and transmission fluids, and aromatic hydrocarbons. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving ketones and esters or low-molecular-weight organic acids call for a different compound.

Maintenance and OEM teams specify it across high-temperature process equipment, semiconductor equipment, and oil and gas.
