568-354 GREEN HNBR (HSN) 70 ORINGS

Part number HS70354 is an AS568-354 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 5.1 in (129.54 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.52 in (140.21 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists petroleum oils and fuels, sour gas and amine inhibitors, and heat and oxidation. HNBR (Hydrogenated Nitrile) is widely chosen for excellent abrasion and tear strength, strong resistance to rapid gas decompression. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). It is not the right choice where strong oxidizing acids or ketones are present.

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