568-276 GREEN HNBR (HSN) 70 ORINGS

This o-ring is supplied in AS568-276 green HNBR (Hydrogenated Nitrile) 70 Shore A measuring an inside diameter of 10.984 in (278.99 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 11.262 in (286.05 mm), catalogued under part number HS70276. It compresses into its gland to block fluid or gas migration across a joint.

As a material, HNBR (Hydrogenated Nitrile) is specified for improved ozone and weathering resistance over standard nitrile, long service life in refrigerant and oilfield duty. This material stands up to heat and oxidation, ozone and weathering, and petroleum oils and fuels. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Applications involving strong oxidizing acids or chlorinated hydrocarbons call for a different compound.

Maintenance and OEM teams specify it across engine timing systems, oilfield and downhole equipment, and automotive air conditioning.

Stocked as HS70276 and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
