HSN (HNBR) 80 568-224

Part number HSN80224 is an AS568-224 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring with an inside diameter of 1.734 in (44.04 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.012 in (51.1 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

HNBR (Hydrogenated Nitrile) is specified here for oil resistance of nitrile with substantially better heat capability, long service life in refrigerant and oilfield duty. This material stands up to ozone and weathering, modern refrigerants, and heat and oxidation. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C).

It sees regular use in engine timing systems, automotive air conditioning, and commercial refrigeration.

HSN80224 ships individually. Unit weight is approximately 1.9738 g and nominal inside diameter is listed as 1 3/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
