Abstract: A process for repairing a hydraulic line having a damaged end section. The damaged end section is severed from the line and a male or female coupling member is formed in the new end. This is accomplished by reducing the wall thickness by increasing the inside diameter (female coupling member) or decreasing the outside diameter (male coupling member). A tubular tip is provided having a major portion the same length as the severed section and an end portion that is an extension of the major portion with a reduced wall thickness forming a male or female coupling member opposite that formed in the end of the tube. Coupling is achieved to regenerate the end section with a consistent inside and outside diameter along the tube and across the coupling intersection.
