568-270 GREEN HNBR (HSN) 70 ORINGS

APG stocks the HS70270, an AS568-270 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 8.984 in (228.19 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.262 in (235.25 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

This material stands up to modern refrigerants, sour gas and amine inhibitors, and petroleum oils and fuels. HNBR (Hydrogenated Nitrile) offers long service life in refrigerant and oilfield duty, improved ozone and weathering resistance over standard nitrile. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service.

Maintenance and OEM teams specify it across heavy-duty powertrain, automotive air conditioning, and engine timing systems.
