HSN (HNBR) 80 568-354

APG stocks the HSN80354, an AS568-354 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring measuring an inside diameter of 5.1 in (129.54 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.52 in (140.21 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, HNBR (Hydrogenated Nitrile) is widely chosen for excellent abrasion and tear strength, the oil resistance of nitrile with substantially better heat capability. It resists heat and oxidation, sour gas and amine inhibitors, and ozone and weathering. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Applications involving esters or ketones call for a different compound.

Typical settings include oilfield and downhole equipment, engine timing systems, and automotive air conditioning.

This item is sold individually under part number HSN80354. Unit weight is approximately 12.113 g and nominal inside diameter is listed as 5 1/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
