568-393 GREEN HNBR (HSN) 70 ORINGS

Part number HS70393 is an AS568-393 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring built to an inside diameter of 23.94 in (608.08 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 24.36 in (618.74 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists sour gas and amine inhibitors, heat and oxidation, and modern refrigerants. HNBR (Hydrogenated Nitrile) is known for the oil resistance of nitrile with substantially better heat capability, long service life in refrigerant and oilfield duty. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Exposure to ketones or chlorinated hydrocarbons will shorten service life.

Maintenance and OEM teams specify it across heavy-duty powertrain, engine timing systems, and automotive air conditioning.

This item is sold individually under part number HS70393. Application requirements vary, so validate compatibility with your process conditions prior to installation.
