This o-ring is supplied in AS568-233 black Buna-N (Nitrile) 70 Shore A built to an inside diameter of 2.859 in (72.62 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.137 in (79.68 mm), catalogued under part number H70233. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists many alcohols, petroleum-based oils, and propane and butane. Buna-N (Nitrile) is widely chosen for low compression set under sustained load, strong abrasion and tear resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in polar solvents or automotive brake fluid.

Common environments for this compound include agricultural equipment, automotive, and hydraulic and pneumatic systems.
