This o-ring is supplied in AS568-411 green HNBR (Hydrogenated Nitrile) 90 Shore A measuring an inside diameter of 2.725 in (69.22 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.275 in (83.19 mm), catalogued under part number HSN90411. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to ozone and weathering, heat and oxidation, and petroleum oils and fuels. HNBR (Hydrogenated Nitrile) is known for the oil resistance of nitrile with substantially better heat capability, excellent abrasion and tear strength. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). It should not be specified for service in strong oxidizing acids or esters.

Typical settings include commercial refrigeration, automotive air conditioning, and heavy-duty powertrain.
