HSN90465 is an AS568-465 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring built to an inside diameter of 17.955 in (456.06 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 18.505 in (470.03 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

It resists sour gas and amine inhibitors, modern refrigerants, and ozone and weathering. HNBR (Hydrogenated Nitrile) offers long service life in refrigerant and oilfield duty, improved ozone and weathering resistance over standard nitrile. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Exposure to chlorinated hydrocarbons or ketones will shorten service life.

Common environments for this compound include engine timing systems, automotive air conditioning, and oilfield and downhole equipment.
