Product Specification

-
This o-ring is supplied in AS568-322 green HNBR (Hydrogenated Nitrile) 70 Shore A supplied with an inside diameter of 1.225 in (31.12 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.645 in (41.78 mm), catalogued under part number HS70322. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, HNBR (Hydrogenated Nitrile) is known for improved ozone and weathering resistance over standard nitrile, long service life in refrigerant and oilfield duty. This material stands up to sour gas and amine inhibitors, heat and oxidation, and modern refrigerants. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with esters or ketones.

Typical settings include engine timing systems, heavy-duty powertrain, and oilfield and downhole equipment.

HS70322 ships individually. Nominal inside diameter is listed as 1 1/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
