This o-ring is supplied in AS568-468 green HNBR (Hydrogenated Nitrile) 70 Shore A supplied with an inside diameter of 19.455 in (494.16 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 20.005 in (508.13 mm), catalogued under part number HS70468. It compresses into its gland to block fluid or gas migration across a joint.

HNBR (Hydrogenated Nitrile) is specified here for improved ozone and weathering resistance over standard nitrile, oil resistance of nitrile with substantially better heat capability. The material holds up against heat and oxidation, ozone and weathering, and modern refrigerants. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. Verify compatibility before use with ketones or esters.

Common environments for this compound include oilfield and downhole equipment, automotive air conditioning, and heavy-duty powertrain.
