568-125 GREEN HNBR (HSN) 70 ORINGS

Ordered as HS70125, this is an AS568-125 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 1.299 in (32.99 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.505 in (38.23 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

HNBR (Hydrogenated Nitrile) is specified here for strong resistance to rapid gas decompression and oil resistance of nitrile with substantially better heat capability. It resists petroleum oils and fuels, modern refrigerants, and sour gas and amine inhibitors. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). It should not be specified for service in esters or chlorinated hydrocarbons.

Common environments for this compound include engine timing systems, automotive air conditioning, and heavy-duty powertrain.

Stocked as HS70125 and sold individually. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
