568-458 GREEN HNBR (HSN) 70 ORINGS

Ordered as HS70458, this is an AS568-458 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring built to an inside diameter of 14.475 in (367.67 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 15.025 in (381.64 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

HNBR (Hydrogenated Nitrile) is specified here for excellent abrasion and tear strength, improved ozone and weathering resistance over standard nitrile. The material holds up against sour gas and amine inhibitors, heat and oxidation, and petroleum oils and fuels. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C). Exposure to esters or ketones will shorten service life.

You will find this material specified across engine timing systems, oilfield and downhole equipment, and heavy-duty powertrain.

This item is sold individually under part number HS70458. Nominal inside diameter is listed as 14 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
