HSN (HNBR) 80 568-352

Part number HSN80352 is an AS568-352 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring with an inside diameter of 4.85 in (123.19 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.27 in (133.86 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists modern refrigerants, sour gas and amine inhibitors, and ozone and weathering. HNBR (Hydrogenated Nitrile) is valued for strong resistance to rapid gas decompression, long service life in refrigerant and oilfield duty. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). It is not the right choice where strong oxidizing acids or ketones are present.

It sees regular use in oilfield and downhole equipment, automotive air conditioning, and heavy-duty powertrain.

This item is sold individually under part number HSN80352. Unit weight is approximately 11.804 g and nominal inside diameter is listed as 4 7/8 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
