568-416 GREEN HNBR (HSN) 70 ORINGS

Part number HS70416 is an AS568-416 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 3.35 in (85.09 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.9 in (99.06 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, HNBR (Hydrogenated Nitrile) is known for strong resistance to rapid gas decompression, improved ozone and weathering resistance over standard nitrile. The compound resists ozone and weathering, petroleum oils and fuels, and heat and oxidation. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). It should not be specified for service in strong oxidizing acids or ketones.

Maintenance and OEM teams specify it across commercial refrigeration, engine timing systems, and heavy-duty powertrain.

Order part number HS70416, sold individually. Nominal inside diameter is listed as 3 3/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
