HSN (HNBR) 80 568-245

This o-ring is supplied in AS568-245 green HNBR (Hydrogenated Nitrile) 80 Shore A measuring an inside diameter of 4.359 in (110.72 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.637 in (117.78 mm), catalogued under part number HSN80245. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

HNBR (Hydrogenated Nitrile) is widely chosen for strong resistance to rapid gas decompression and the oil resistance of nitrile with substantially better heat capability. Expect good resistance to ozone and weathering, modern refrigerants, and heat and oxidation. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C).

You will find this material specified across commercial refrigeration, automotive air conditioning, and heavy-duty powertrain.
