HSN (HNBR) 80 568-222

Ordered as HSN80222, this is an AS568-222 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring with an inside diameter of 1.484 in (37.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.762 in (44.75 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to petroleum oils and fuels, modern refrigerants, and sour gas and amine inhibitors. HNBR (Hydrogenated Nitrile) is valued for long service life in refrigerant and oilfield duty, strong resistance to rapid gas decompression. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Applications involving esters or strong oxidizing acids call for a different compound.

Typical settings include oilfield and downhole equipment, heavy-duty powertrain, and engine timing systems.

Stocked as HSN80222 and sold individually. Unit weight is approximately 1.624 g and nominal inside diameter is listed as 1 1/2 inch. Review your operating media and conditions against this specification before installation.
