HSN (HNBR) 80 568-015

Part number HSN80015 is an AS568-015 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring measuring an inside diameter of 0.551 in (14 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.691 in (17.55 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

HNBR (Hydrogenated Nitrile) offers strong resistance to rapid gas decompression, long service life in refrigerant and oilfield duty. The compound resists sour gas and amine inhibitors, heat and oxidation, and modern refrigerants. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. It is not the right choice where ketones or esters are present.

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