568-110 HSN90 DURO ORINGS

The HSN90110 is an AS568-110 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 0.362 in (9.19 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.568 in (14.43 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

HNBR (Hydrogenated Nitrile) is specified here for oil resistance of nitrile with substantially better heat capability, long service life in refrigerant and oilfield duty. It resists sour gas and amine inhibitors, modern refrigerants, and petroleum oils and fuels. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Applications involving esters or chlorinated hydrocarbons call for a different compound.

Maintenance and OEM teams specify it across oilfield and downhole equipment, engine timing systems, and commercial refrigeration.

This item is sold individually under part number HSN90110. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
