HSN (HNBR) 80 568-339

The HSN80339 is an AS568-339 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring supplied with an inside diameter of 3.225 in (81.92 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.645 in (92.58 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists petroleum oils and fuels, ozone and weathering, and heat and oxidation. HNBR (Hydrogenated Nitrile) is widely chosen for strong resistance to rapid gas decompression, excellent abrasion and tear strength. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). It is not the right choice where esters or strong oxidizing acids are present.

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