568-115 HSN90 DURO ORINGS

Part number HSN90115 is an AS568-115 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring measuring an inside diameter of 0.674 in (17.12 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.88 in (22.35 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

It resists heat and oxidation, sour gas and amine inhibitors, and modern refrigerants. HNBR (Hydrogenated Nitrile) is known for the oil resistance of nitrile with substantially better heat capability and strong resistance to rapid gas decompression. 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 chlorinated hydrocarbons or esters are present.

Maintenance and OEM teams specify it across oilfield and downhole equipment, automotive air conditioning, and heavy-duty powertrain.
