568-127 GREEN HNBR (HSN) 70 ORINGS

HS70127 is an AS568-127 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 1.424 in (36.17 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.63 in (41.4 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

It resists heat and oxidation, sour gas and amine inhibitors, and petroleum oils and fuels. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is valued for improved ozone and weathering resistance over standard nitrile, excellent abrasion and tear strength. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. Applications involving strong oxidizing acids or esters call for a different compound.

Typical settings include commercial refrigeration, engine timing systems, and automotive air conditioning.

Order part number HS70127, sold individually. Nominal inside diameter is listed as 1 7/16 inch. Check the compound against your process media, pressure and temperature before committing to a design.
