HSN (HNBR) 80 568-167

Ordered as HSN80167, this is an AS568-167 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring supplied with an inside diameter of 6.987 in (177.47 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.193 in (182.7 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, HNBR (Hydrogenated Nitrile) is widely chosen for long service life in refrigerant and oilfield duty, improved ozone and weathering resistance over standard nitrile. It resists ozone and weathering, petroleum oils and fuels, and modern refrigerants. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C). It should not be specified for service in strong oxidizing acids or chlorinated hydrocarbons.

Common environments for this compound include heavy-duty powertrain, automotive air conditioning, and commercial refrigeration.

Reference part number HSN80167 when ordering; the item is sold individually. Nominal inside diameter is listed as 7 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
