568-034 GREEN HNBR (HSN) 70 ORINGS

APG stocks the HS70034, an AS568-034 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring built to an inside diameter of 2.114 in (53.7 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.254 in (57.25 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, HNBR (Hydrogenated Nitrile) delivers strong resistance to rapid gas decompression, improved ozone and weathering resistance over standard nitrile. It resists sour gas and amine inhibitors, heat and oxidation, and ozone and weathering. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C).

You will find this material specified across automotive air conditioning, engine timing systems, and heavy-duty powertrain.

HS70034 ships individually. Nominal inside diameter is listed as 2 1/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
