A sleeve is disclosed for use with a piston of a hydraulic hammer. The sleeve may have a generally cylindrical body with a top end and a bottom end, and a central bore passing axially from the top end of the generally cylindrical body to the bottom end. The generally cylindrical body may be a composite structure including a guide layer forming an inner annular surface of the central bore, an energizer layer located radially outward of the guide layer and being bonded to the guide layer, and a support layer bonded to the energizer layer. The support layer may form an outer surface of the generally cylindrical body.
