HSN (HNBR) 80 568-375

Part number HSN80375 is an AS568-375 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring supplied with an inside diameter of 9.475 in (240.67 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 9.895 in (251.33 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists sour gas and amine inhibitors, heat and oxidation, and petroleum oils and fuels. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is valued for long service life in refrigerant and oilfield duty, the oil resistance of nitrile with substantially better heat capability. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C). It is not the right choice where ketones or strong oxidizing acids are present.

Common environments for this compound include automotive air conditioning, oilfield and downhole equipment, and heavy-duty powertrain.

HSN80375 ships individually. Unit weight is approximately 22.952 g and nominal inside diameter is listed as 9 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
