This o-ring is supplied in AS568-272 black Viton® (FKM) 75 Shore A built to an inside diameter of 9.484 in (240.89 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.762 in (247.95 mm), catalogued under part number VITON75272. It compresses into its gland to block fluid or gas migration across a joint.

As a material, Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. It resists petroleum oils and fuels, aromatic hydrocarbons, and chlorinated solvents. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.

It sees regular use in oil and gas, chemical processing, and automotive fuel systems.
