This o-ring is supplied in AS568-260 green HNBR (Hydrogenated Nitrile) 70 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 HS70260. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.
HNBR (Hydrogenated Nitrile) is valued for the oil resistance of nitrile with substantially better heat capability and strong resistance to rapid gas decompression. The compound resists heat and oxidation, modern refrigerants, and ozone and weathering. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. Exposure to strong oxidizing acids or chlorinated hydrocarbons will shorten service life.
It sees regular use in oilfield and downhole equipment, engine timing systems, and heavy-duty powertrain.
This item is sold individually under part number HS70260. Nominal inside diameter is listed as 6 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
