Resilon Polyurethane O-Rings (568)

Parker’s Resilon® 568 Profile polyurethane O-rings provide the material advantages of Resilon polyurethanes in standard O-ring sizes.  

The high extrusion resistance of the Resilon family of polyurethane materials eliminates the need for a back-up in many hydraulic applications, thereby simplifying installation and reducing groove width.

Resilon’s unmatched temperature rating makes it suitable in applications where other urethanes fail.  

In addition, Resilon 4301 polyurethane provides superior water resistance and compression set resistance in water-based fluids.  

Premium urethane O-rings are much less prone to spiral failure and installation damage compared with rubber O-rings.

For use in static and dynamic applications for hydraulics and pneumatics, the dimensions and tolerances of Parker Resilon 568 Profile O-rings match up with AS568B size specifications for diameter and cross-section and are used in the same grooves.
