HSN (HNBR) 80 568-229

The HSN80229 is an AS568-229 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring measuring an inside diameter of 2.359 in (59.92 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.637 in (66.98 mm). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against heat and oxidation, sour gas and amine inhibitors, and modern refrigerants. HNBR (Hydrogenated Nitrile) is valued for the oil resistance of nitrile with substantially better heat capability and strong resistance to rapid gas decompression. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C). It is not the right choice where strong oxidizing acids or esters are present.

It sees regular use in automotive air conditioning, oilfield and downhole equipment, and engine timing systems.
