568-315 GREEN HNBR (HSN) 70 ORINGS

HS70315 is an AS568-315 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 0.787 in (19.99 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.207 in (30.66 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to modern refrigerants, petroleum oils and fuels, and ozone and weathering. HNBR (Hydrogenated Nitrile) is widely chosen for strong resistance to rapid gas decompression, improved ozone and weathering resistance over standard nitrile. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. It is not the right choice where ketones or esters are present.

You will find this material specified across heavy-duty powertrain, engine timing systems, and commercial refrigeration.
