568-032 HSN90 DURO ORINGS

APG stocks the HSN90032, an AS568-032 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring measuring an inside diameter of 1.864 in (47.35 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.004 in (50.9 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to modern refrigerants, ozone and weathering, and petroleum oils and fuels. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is known for long service life in refrigerant and oilfield duty, the oil resistance of nitrile with substantially better heat capability. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C).

You will find this material specified across engine timing systems, automotive air conditioning, and heavy-duty powertrain.

This item is sold individually under part number HSN90032. Check the compound against your process media, pressure and temperature before committing to a design.
