568-432 GREEN HNBR (HSN) 70 ORINGS

APG stocks the HS70432, an AS568-432 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 5.35 in (135.89 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.9 in (149.86 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists petroleum oils and fuels, sour gas and amine inhibitors, and ozone and weathering. HNBR (Hydrogenated Nitrile) is known for 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. Exposure to strong oxidizing acids or chlorinated hydrocarbons will shorten service life.

Typical settings include commercial refrigeration, automotive air conditioning, and oilfield and downhole equipment.

HS70432 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
