The HSN90160 is an AS568-160 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 5.237 in (133.02 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 5.443 in (138.25 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

HNBR (Hydrogenated Nitrile) is valued for excellent abrasion and tear strength, the oil resistance of nitrile with substantially better heat capability. It resists petroleum oils and fuels, ozone and weathering, and heat and oxidation. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). It should not be specified for service in chlorinated hydrocarbons or ketones.

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