4MM CS X 355MM ID BLACK FKM 75D

Part number V4X355 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 355 mm (13.976 in), a cross section of 4 mm (0.157 in), and an outside diameter of 363 mm (14.29 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to engine and transmission fluids, chlorinated solvents, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) delivers outstanding high-temperature capability and long service life in hot, chemically aggressive environments. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving hot water and steam or ketones and esters call for a different compound.

You will find this material specified across chemical processing, high-temperature process equipment, and oil and gas.
