This o-ring is supplied in AS568-376 black Buna-N (Nitrile) 70 Shore A built to an inside diameter of 9.725 in (247.02 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 10.145 in (257.68 mm), catalogued under part number H70MD376. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Buna-N (Nitrile) is valued for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. Expect good resistance to petroleum-based oils, propane and butane, and greases and lubricants. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to strong acids or ozone and direct sunlight will shorten service life.

This o-ring is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include agricultural equipment, construction equipment, and automotive.
