568-383 HSN90 DURO ORINGS

Part number HSN90383 is an AS568-383 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring with an inside diameter of 13.975 in (354.97 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 14.395 in (365.63 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against sour gas and amine inhibitors, petroleum oils and fuels, and ozone and weathering. HNBR (Hydrogenated Nitrile) is valued for strong resistance to rapid gas decompression and the oil resistance of nitrile with substantially better heat capability. 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, heavy-duty powertrain, and commercial refrigeration.

HSN90383 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
