568-136 GREEN HNBR (HSN) 70 ORINGS

This o-ring is supplied in AS568-136 green HNBR (Hydrogenated Nitrile) 70 Shore A supplied with an inside diameter of 1.987 in (50.47 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.193 in (55.7 mm), catalogued under part number HS70136. It delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against petroleum oils and fuels, ozone and weathering, and heat and oxidation. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) offers long service life in refrigerant and oilfield duty, the oil resistance of nitrile with substantially better heat capability. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Verify compatibility before use with strong oxidizing acids or ketones.

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

This item is sold individually under part number HS70136. Nominal inside diameter is listed as 2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
