HSN (HNBR) 80 568-123

Part number HSN80123 is an AS568-123 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring built to an inside diameter of 1.174 in (29.82 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.38 in (35.05 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists petroleum oils and fuels, modern refrigerants, and heat and oxidation. HNBR (Hydrogenated Nitrile) is valued for 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). Verify compatibility before use with chlorinated hydrocarbons or strong oxidizing acids.

Typical settings include automotive air conditioning, commercial refrigeration, and engine timing systems.
