568-314 GREEN HNBR (HSN) 70 ORINGS

Part number HS70314 is an AS568-314 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 0.725 in (18.42 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.145 in (29.08 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists heat and oxidation, petroleum oils and fuels, and sour gas and amine inhibitors. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is known for excellent abrasion and tear strength, strong resistance to rapid gas decompression. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). It is not the right choice where strong oxidizing acids or esters are present.

Common environments for this compound include automotive air conditioning, commercial refrigeration, and heavy-duty powertrain.

Stocked as HS70314 and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
