HSN (HNBR) 80 568-134

The HSN80134 is an AS568-134 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring measuring an inside diameter of 1.862 in (47.29 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.068 in (52.53 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

HNBR (Hydrogenated Nitrile) is specified here for excellent abrasion and tear strength, strong resistance to rapid gas decompression. The material holds up against ozone and weathering, petroleum oils and fuels, and heat and oxidation. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with strong oxidizing acids or esters.

Maintenance and OEM teams specify it across automotive air conditioning, commercial refrigeration, and oilfield and downhole equipment.
