HSN (HNBR) 80 568-035

This o-ring is supplied in AS568-035 green HNBR (Hydrogenated Nitrile) 80 Shore A measuring an inside diameter of 2.239 in (56.87 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.379 in (60.43 mm), catalogued under part number HSN80035. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to modern refrigerants, petroleum oils and fuels, and heat and oxidation. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is valued for strong resistance to rapid gas decompression, improved ozone and weathering resistance over standard nitrile. 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 esters or chlorinated hydrocarbons are present.

Common environments for this compound include engine timing systems, commercial refrigeration, and heavy-duty powertrain.

Reference part number HSN80035 when ordering; the item is sold individually. Check the compound against your process media, pressure and temperature before committing to a design.
