Part number HSN90341 is an AS568-341 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring measuring an inside diameter of 3.475 in (88.27 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.895 in (98.93 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

HNBR (Hydrogenated Nitrile) is specified here for improved ozone and weathering resistance over standard nitrile, long service life in refrigerant and oilfield duty. The material holds up against sour gas and amine inhibitors, heat and oxidation, and ozone and weathering. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). It is not the right choice where chlorinated hydrocarbons or strong oxidizing acids are present.

You will find this material specified across oilfield and downhole equipment, engine timing systems, and heavy-duty powertrain.
