This o-ring is supplied in AS568-382 green HNBR (Hydrogenated Nitrile) 90 Shore A measuring an inside diameter of 12.975 in (329.57 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 13.395 in (340.23 mm), catalogued under part number HSN90382. It compresses into its gland to block fluid or gas migration across a joint.

As a material, HNBR (Hydrogenated Nitrile) offers the oil resistance of nitrile with substantially better heat capability, long service life in refrigerant and oilfield duty. Expect good resistance to petroleum oils and fuels, modern refrigerants, and ozone and weathering. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Applications involving strong oxidizing acids or esters call for a different compound.

It sees regular use in commercial refrigeration, automotive air conditioning, and heavy-duty powertrain.

Order part number HSN90382, sold individually. Nominal inside diameter is listed as 13 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
