568-417 GREEN HNBR (HSN) 70 ORINGS

Part number HS70417 is an AS568-417 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring built to an inside diameter of 3.475 in (88.27 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.025 in (102.24 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

HNBR (Hydrogenated Nitrile) is valued for improved ozone and weathering resistance over standard nitrile, the oil resistance of nitrile with substantially better heat capability. The material holds up against heat and oxidation, modern refrigerants, and sour gas and amine inhibitors. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. Verify compatibility before use with chlorinated hydrocarbons or ketones.

Common environments for this compound include commercial refrigeration, engine timing systems, and heavy-duty powertrain.

HS70417 ships individually. Check the compound against your process media, pressure and temperature before committing to a design.
