HSN (HNBR) 80 568-902

Ordered as HSN80902, this is an AS568-902 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring measuring an inside diameter of 0.239 in (6.07 mm), a cross section of 0.064 in (1.63 mm), and an outside diameter of 0.367 in (9.32 mm). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.

As a material, HNBR (Hydrogenated Nitrile) is widely chosen for long service life in refrigerant and oilfield duty, excellent abrasion and tear strength. It resists modern refrigerants, heat and oxidation, and ozone and weathering. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. Applications involving chlorinated hydrocarbons or esters call for a different compound.

It sees regular use in engine timing systems, commercial refrigeration, and automotive air conditioning.

HSN80902 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
