HSN (HNBR) 80 568-473

APG stocks the HSN80473, an AS568-473 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring built to an inside diameter of 23.94 in (608.08 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 24.49 in (622.05 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists heat and oxidation, modern refrigerants, and ozone and weathering. HNBR (Hydrogenated Nitrile) is specified for long service life in refrigerant and oilfield duty, the oil resistance of nitrile with substantially better heat capability. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Exposure to strong oxidizing acids or chlorinated hydrocarbons will shorten service life.

Common environments for this compound include heavy-duty powertrain, engine timing systems, and automotive air conditioning.
