HSN (HNBR) 80 568-215

Part number HSN80215 is an AS568-215 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring 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). An o-ring compresses into its gland to block fluid or gas migration across a joint.

HNBR (Hydrogenated Nitrile) is valued for the oil resistance of nitrile with substantially better heat capability, long service life in refrigerant and oilfield duty. It resists petroleum oils and fuels, sour gas and amine inhibitors, and heat and oxidation. Published continuous service range is -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 commercial refrigeration, automotive air conditioning, and engine timing systems.

Order part number HSN80215, sold individually. Unit weight is approximately 1.2416 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
