568-111 GREEN HNBR (HSN) 70 ORINGS

This o-ring is supplied in AS568-111 green HNBR (Hydrogenated Nitrile) 70 Shore A with an inside diameter of 0.424 in (10.77 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.63 in (16 mm), catalogued under part number HS70111. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to modern refrigerants, petroleum oils and fuels, and heat and oxidation. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is specified for long service life in refrigerant and oilfield duty, the oil resistance of nitrile with substantially better heat capability. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C). It is not the right choice where esters or chlorinated hydrocarbons are present.

You will find this material specified across engine timing systems, heavy-duty powertrain, and oilfield and downhole equipment.

HS70111 ships individually. Unit weight is approximately 0.3137 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
