568-411 GREEN HNBR (HSN) 70 ORINGS

Ordered as HS70411, this is an AS568-411 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 2.725 in (69.22 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.275 in (83.19 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The compound resists modern refrigerants, sour gas and amine inhibitors, and petroleum oils and fuels. HNBR (Hydrogenated Nitrile) is widely chosen for excellent abrasion and tear strength, improved ozone and weathering resistance over standard nitrile. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C).

You will find this material specified across oilfield and downhole equipment, automotive air conditioning, and commercial refrigeration.

Stocked as HS70411 and sold individually. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
