HSN (HNBR) 80 568-392

Ordered as HSN80392, this is an AS568-392 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring built to an inside diameter of 22.94 in (582.68 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 23.36 in (593.34 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

HNBR (Hydrogenated Nitrile) is specified here for long service life in refrigerant and oilfield duty, improved ozone and weathering resistance over standard nitrile. This material stands up to sour gas and amine inhibitors, petroleum oils and fuels, and modern refrigerants. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Exposure to strong oxidizing acids or chlorinated hydrocarbons will shorten service life.

You will find this material specified across engine timing systems, commercial refrigeration, and oilfield and downhole equipment.

This item is sold individually under part number HSN80392. Nominal inside diameter is listed as 23 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
