568-456 GREEN HNBR (HSN) 70 ORINGS

HS70456 is an AS568-456 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 13.475 in (342.27 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 14.025 in (356.24 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against heat and oxidation, sour gas and amine inhibitors, and petroleum oils and fuels. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) delivers improved ozone and weathering resistance over standard nitrile, strong resistance to rapid gas decompression. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Verify compatibility before use with esters or strong oxidizing acids.

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

Stocked as HS70456 and sold individually. Nominal inside diameter is listed as 13 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
