HSN (HNBR) 80 568-384

The HSN80384 is an AS568-384 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring built to an inside diameter of 14.975 in (380.37 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 15.395 in (391.03 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists modern refrigerants, ozone and weathering, and sour gas and amine inhibitors. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is known for strong resistance to rapid gas decompression, improved ozone and weathering resistance over standard nitrile. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C).

Maintenance and OEM teams specify it across oilfield and downhole equipment, engine timing systems, and heavy-duty powertrain.

Reference part number HSN80384 when ordering; the item is sold individually. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
