568-114 GREEN HNBR (HSN) 70 ORINGS

APG stocks the HS70114, an AS568-114 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 0.612 in (15.54 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.818 in (20.78 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to sour gas and amine inhibitors, ozone and weathering, and heat and oxidation. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is widely chosen for excellent abrasion and tear strength, improved ozone and weathering resistance over standard nitrile. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C). Exposure to chlorinated hydrocarbons or ketones will shorten service life.

It sees regular use in commercial refrigeration, heavy-duty powertrain, and automotive air conditioning.

Order part number HS70114, sold individually. Unit weight is approximately 0.4095 g and nominal inside diameter is listed as 5/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
