568-274 GREEN HNBR (HSN) 70 ORINGS

The HS70274 is an AS568-274 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 9.984 in (253.59 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 10.262 in (260.65 mm). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.

HNBR (Hydrogenated Nitrile) is specified here for oil resistance of nitrile with substantially better heat capability, long service life in refrigerant and oilfield duty. The compound resists modern refrigerants, heat and oxidation, and petroleum oils and fuels. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Exposure to esters or chlorinated hydrocarbons will shorten service life.

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

Order part number HS70274, sold individually. Nominal inside diameter is listed as 10 inch. Check the compound against your process media, pressure and temperature before committing to a design.
