568-026 GREEN HNBR (HSN) 70 ORINGS

Part number HS70026 is an AS568-026 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring built to an inside diameter of 1.239 in (31.47 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.379 in (35.03 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

HNBR (Hydrogenated Nitrile) offers long service life in refrigerant and oilfield duty, the oil resistance of nitrile with substantially better heat capability. This material stands up to modern refrigerants, sour gas and amine inhibitors, and petroleum oils and fuels. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with esters or chlorinated hydrocarbons.

Maintenance and OEM teams specify it across engine timing systems, heavy-duty powertrain, and oilfield and downhole equipment.

Reference part number HS70026 when ordering; the item is sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
