HSN (HNBR) 80 568-260

This o-ring is supplied in AS568-260 green HNBR (Hydrogenated Nitrile) 80 Shore A measuring an inside diameter of 6.484 in (164.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 6.762 in (171.75 mm), catalogued under part number HSN80260. It delivers dependable bidirectional sealing in a compact groove envelope.

It resists heat and oxidation, modern refrigerants, and petroleum oils and fuels. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is valued for the oil resistance of nitrile with substantially better heat capability, excellent abrasion and tear strength. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Exposure to esters or chlorinated hydrocarbons will shorten service life.

Common environments for this compound include heavy-duty powertrain, oilfield and downhole equipment, and engine timing systems.

Order part number HSN80260, sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
