568-001 HSN90 DURO ORINGS

Part number HSN90001 is an AS568-001 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring with an inside diameter of 0.029 in (0.74 mm), a cross section of 0.04 in (1.02 mm), and an outside diameter of 0.109 in (2.77 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to petroleum oils and fuels, ozone and weathering, and sour gas and amine inhibitors. HNBR (Hydrogenated Nitrile) is widely chosen for excellent abrasion and tear strength, long service life in refrigerant and oilfield duty. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service.

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

HSN90001 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
