568-008 GREEN HNBR (HSN) 70 ORINGS

APG stocks the HS70008, an AS568-008 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring built to an inside diameter of 0.176 in (4.47 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.316 in (8.03 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists modern refrigerants, sour gas and amine inhibitors, and petroleum oils and fuels. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) delivers the oil resistance of nitrile with substantially better heat capability and strong resistance to rapid gas decompression. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service.

Typical settings include commercial refrigeration, engine timing systems, and heavy-duty powertrain.

This item is sold individually under part number HS70008. Unit weight is approximately 0.068 g and nominal inside diameter is listed as 3/16 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
