Repairing a bushing is less expensive than purchasing a new bushing and you are able to maintain all of the original dimensions.

A typical bushing repair is a regasket of the bushing or a recore and regasket of the bushing. When a bushing leaks; however, tests well, a regasket will be performed in which the sealing components are replaced. When a bushing tests poor, a recore and regasket will be performed. During the recore of a bushing the bushing core will be replaced with a new PCORE® POC type core. Repaired bushings ship with the same warranty as a new bushing.
