568-334 GREEN HNBR (HSN) 70 ORINGS

The HS70334 is an AS568-334 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 2.6 in (66.04 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.02 in (76.71 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against petroleum oils and fuels, sour gas and amine inhibitors, and heat and oxidation. HNBR (Hydrogenated Nitrile) delivers the oil resistance of nitrile with substantially better heat capability, improved ozone and weathering resistance over standard nitrile. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Applications involving esters or ketones call for a different compound.

It sees regular use in engine timing systems, automotive air conditioning, and commercial refrigeration.

Stocked as HS70334 and sold individually. Nominal inside diameter is listed as 2 5/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
