568-395 GREEN HNBR (HSN) 70 ORINGS

Part number HS70395 is an AS568-395 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 25.94 in (658.88 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 26.36 in (669.54 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, HNBR (Hydrogenated Nitrile) is specified for improved ozone and weathering resistance over standard nitrile, the oil resistance of nitrile with substantially better heat capability. Expect good resistance to ozone and weathering, petroleum oils and fuels, and sour gas and amine inhibitors. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Applications involving chlorinated hydrocarbons or strong oxidizing acids call for a different compound.

Maintenance and OEM teams specify it across commercial refrigeration, heavy-duty powertrain, and automotive air conditioning.
