-212 BLACK FKM 75D O-RING

The V75212 is an AS568-212 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 0.859 in (21.82 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.137 in (28.88 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists engine and transmission fluids, many acids, and aromatic hydrocarbons. Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).

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

This item is sold individually under part number V75212. Nominal inside diameter is listed as 7/8 inch. Check the compound against your process media, pressure and temperature before committing to a design.
