568-153 HSN90 DURO ORINGS

APG stocks the HSN90153, an AS568-153 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring measuring an inside diameter of 3.487 in (88.57 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.693 in (93.8 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, HNBR (Hydrogenated Nitrile) is specified for improved ozone and weathering resistance over standard nitrile, long service life in refrigerant and oilfield duty. This material stands up to sour gas and amine inhibitors, heat and oxidation, and ozone and weathering. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). It should not be specified for service in strong oxidizing acids or esters.

You will find this material specified across oilfield and downhole equipment, commercial refrigeration, and automotive air conditioning.

Stocked as HSN90153 and sold individually. Unit weight is approximately 2.0262 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
