568-928 HSN90 DURO ORINGS

APG stocks the HSN90928, an AS568-928 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring built to an inside diameter of 2.09 in (53.09 mm), a cross section of 0.118 in (3 mm), and an outside diameter of 2.326 in (59.08 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, HNBR (Hydrogenated Nitrile) is known for the oil resistance of nitrile with substantially better heat capability and strong resistance to rapid gas decompression. This material stands up to sour gas and amine inhibitors, modern refrigerants, and heat and oxidation. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. It is not the right choice where esters or strong oxidizing acids are present.

Common environments for this compound include heavy-duty powertrain, engine timing systems, and automotive air conditioning.
