568-455 GREEN HNBR (HSN) 70 ORINGS

HS70455 is an AS568-455 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 12.975 in (329.57 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 13.525 in (343.54 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

HNBR (Hydrogenated Nitrile) offers the oil resistance of nitrile with substantially better heat capability, excellent abrasion and tear strength. It resists sour gas and amine inhibitors, heat and oxidation, and petroleum oils and fuels. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C).

Maintenance and OEM teams specify it across automotive air conditioning, commercial refrigeration, and heavy-duty powertrain.

HS70455 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
