HSN (HNBR) 80 568-269

This o-ring is supplied in AS568-269 green HNBR (Hydrogenated Nitrile) 80 Shore A with an inside diameter of 8.734 in (221.84 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.012 in (228.9 mm), catalogued under part number HSN80269. It compresses into its gland to block fluid or gas migration across a joint.

This material stands up to heat and oxidation, ozone and weathering, and petroleum oils and fuels. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) delivers excellent abrasion and tear strength, strong resistance to rapid gas decompression. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Exposure to chlorinated hydrocarbons or ketones will shorten service life.

Maintenance and OEM teams specify it across commercial refrigeration, oilfield and downhole equipment, and engine timing systems.

Stocked as HSN80269 and sold individually. Nominal inside diameter is listed as 8 3/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
