HSN (HNBR) 80 568-360

Ordered as HSN80360, this is an AS568-360 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring measuring an inside diameter of 5.85 in (148.59 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.27 in (159.26 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

It resists petroleum oils and fuels, modern refrigerants, and ozone and weathering. HNBR (Hydrogenated Nitrile) is widely chosen for excellent abrasion and tear strength, strong resistance to rapid gas decompression. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). It is not the right choice where chlorinated hydrocarbons or strong oxidizing acids are present.

It sees regular use in heavy-duty powertrain, commercial refrigeration, and automotive air conditioning.

Order part number HSN80360, sold individually. Unit weight is approximately 0.0135 g and nominal inside diameter is listed as 5 7/8 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
