568-454 GREEN HNBR (HSN) 70 ORINGS

Part number HS70454 is an AS568-454 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 12.475 in (316.87 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 13.025 in (330.84 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

HNBR (Hydrogenated Nitrile) is specified for improved ozone and weathering resistance over standard nitrile, long service life in refrigerant and oilfield duty. The compound resists sour gas and amine inhibitors, modern refrigerants, and heat and oxidation. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). It is not the right choice where esters or strong oxidizing acids are present.

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

HS70454 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
