4MM CS X 88MM ID BLACK FKM 75D

This o-ring is supplied in black Viton® (FKM) 75 Shore A built to an inside diameter of 88 mm (3.465 in), a cross section of 4 mm (0.157 in), and an outside diameter of 96 mm (3.78 in), catalogued under part number V4X88. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Viton® (FKM) is specified here for industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. The compound resists aggressive chemicals, many acids, and aromatic hydrocarbons. Continuous operating temperature is published at -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.

It sees regular use in chemical processing, high-temperature process equipment, and semiconductor equipment.

V4X88 ships individually. Unit weight is approximately 6.652 g. Check the compound against your process media, pressure and temperature before committing to a design.
