HSN (HNBR) 80 568-910

Ordered as HSN80910, this is an AS568-910 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring built to an inside diameter of 0.755 in (19.18 mm), a cross section of 0.097 in (2.46 mm), and an outside diameter of 0.949 in (24.1 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

HNBR (Hydrogenated Nitrile) delivers the oil resistance of nitrile with substantially better heat capability, excellent abrasion and tear strength. Expect good resistance to modern refrigerants, petroleum oils and fuels, and heat and oxidation. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with esters or strong oxidizing acids.

Typical settings include engine timing systems, commercial refrigeration, and oilfield and downhole equipment.

Stocked as HSN80910 and sold individually. Nominal inside diameter is listed as 5/8 inch. Check the compound against your process media, pressure and temperature before committing to a design.
