HSN (HNBR) 80 568-113

HSN80113 is an AS568-113 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring built to an inside diameter of 0.549 in (13.94 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.755 in (19.18 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to heat and oxidation, modern refrigerants, and sour gas and amine inhibitors. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is widely chosen for improved ozone and weathering resistance over standard nitrile, long service life in refrigerant and oilfield duty. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C).

You will find this material specified across heavy-duty powertrain, engine timing systems, and automotive air conditioning.

This item is sold individually under part number HSN80113. Unit weight is approximately 0.3762 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
