This o-ring is supplied in AS568-158 green HNBR (Hydrogenated Nitrile) 90 Shore A supplied with an inside diameter of 4.737 in (120.32 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 4.943 in (125.55 mm), catalogued under part number HSN90158. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, HNBR (Hydrogenated Nitrile) delivers excellent abrasion and tear strength, strong resistance to rapid gas decompression. This material stands up to modern refrigerants, sour gas and amine inhibitors, and ozone and weathering. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). It is not the right choice where chlorinated hydrocarbons or strong oxidizing acids are present.

Common environments for this compound include engine timing systems, commercial refrigeration, and heavy-duty powertrain.

HSN90158 ships individually. Nominal inside diameter is listed as 4 3/4 inch. Review your operating media and conditions against this specification before installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
