568-215 HSN90 DURO ORINGS

This o-ring is supplied in AS568-215 green HNBR (Hydrogenated Nitrile) 90 Shore A built to an inside diameter of 1.046 in (26.57 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.324 in (33.63 mm), catalogued under part number HSN90215. It compresses into its gland to block fluid or gas migration across a joint.

The material holds up against ozone and weathering, modern refrigerants, and heat and oxidation. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) delivers long service life in refrigerant and oilfield duty, strong resistance to rapid gas decompression. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with chlorinated hydrocarbons or esters.

You will find this material specified across oilfield and downhole equipment, commercial refrigeration, and engine timing systems.
