568-911 GREEN HNBR (HSN) 70 ORINGS

Part number HS70911 is an AS568-911 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 0.863 in (21.92 mm), a cross section of 0.116 in (2.95 mm), and an outside diameter of 1.095 in (27.81 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to heat and oxidation, petroleum oils and fuels, and modern refrigerants. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) delivers strong resistance to rapid gas decompression, long service life in refrigerant and oilfield duty. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Exposure to chlorinated hydrocarbons or strong oxidizing acids will shorten service life.

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