HSN (HNBR) 80 568-133

This o-ring is supplied in AS568-133 green HNBR (Hydrogenated Nitrile) 80 Shore A with an inside diameter of 1.799 in (45.69 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.005 in (50.93 mm), catalogued under part number HSN80133. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against ozone and weathering, heat and oxidation, and sour gas and amine inhibitors. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is valued for long service life in refrigerant and oilfield duty, the oil resistance of nitrile with substantially better heat capability. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service.

Common environments for this compound include commercial refrigeration, oilfield and downhole equipment, and automotive air conditioning.

This item is sold individually under part number HSN80133. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
