HSN (HNBR) 80 568-350

This o-ring is supplied in AS568-350 green HNBR (Hydrogenated Nitrile) 80 Shore A supplied with an inside diameter of 4.6 in (116.84 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.02 in (127.51 mm), catalogued under part number HSN80350. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

HNBR (Hydrogenated Nitrile) is widely chosen for strong resistance to rapid gas decompression and the oil resistance of nitrile with substantially better heat capability. This material stands up to modern refrigerants, heat and oxidation, and sour gas and amine inhibitors. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Verify compatibility before use with ketones or strong oxidizing acids.

Maintenance and OEM teams specify it across heavy-duty powertrain, commercial refrigeration, and engine timing systems.

HSN80350 ships individually. Unit weight is approximately 10.9898 g and nominal inside diameter is listed as 4 5/8 inch.
