568-364 GREEN HNBR (HSN) 70 ORINGS

Part number HS70364 is an AS568-364 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 6.725 in (170.82 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 7.145 in (181.48 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound 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 improved ozone and weathering resistance over standard nitrile, excellent abrasion and tear strength. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C).

It sees regular use in oilfield and downhole equipment, automotive air conditioning, and heavy-duty powertrain.

This item is sold individually under part number HS70364. Nominal inside diameter is listed as 6 3/4 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
