-237 BLACK FKM 75D O-RING

V75237 is an AS568-237 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 3.359 in (85.32 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.637 in (92.38 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Viton® (FKM) is known for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. It resists many acids, aromatic hydrocarbons, and engine and transmission fluids. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Applications involving hot water and steam or low-molecular-weight organic acids call for a different compound.

Maintenance and OEM teams specify it across chemical processing, high-temperature process equipment, and aerospace.

This item is sold individually under part number V75237. Unit weight is approximately 5.09 g. Check the compound against your process media, pressure and temperature before committing to a design.
