568-130 HSN90 DURO ORINGS

APG stocks the HSN90130, an AS568-130 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 1.612 in (40.94 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.818 in (46.18 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists sour gas and amine inhibitors, modern refrigerants, and heat and oxidation. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is specified for excellent abrasion and tear strength, strong resistance to rapid gas decompression. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). It should not be specified for service in chlorinated hydrocarbons or strong oxidizing acids.

Typical settings include heavy-duty powertrain, engine timing systems, and commercial refrigeration.

This item is sold individually under part number HSN90130. Nominal inside diameter is listed as 1 5/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
