HSN (HNBR) 80 568-914

HSN80914 is an AS568-914 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring built to an inside diameter of 1.047 in (26.59 mm), a cross section of 0.116 in (2.95 mm), and an outside diameter of 1.279 in (32.49 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

HNBR (Hydrogenated Nitrile) is specified here for improved ozone and weathering resistance over standard nitrile, oil resistance of nitrile with substantially better heat capability. The material holds up against sour gas and amine inhibitors, modern refrigerants, and petroleum oils and fuels. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with strong oxidizing acids or esters.

Maintenance and OEM teams specify it across commercial refrigeration, heavy-duty powertrain, and automotive air conditioning.

This item is sold individually under part number HSN80914. Nominal inside diameter is listed as 7/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
