PURPOSE:To improve reliability in joint by improving fitting strength of a fitting part of a faucet short pipe to an original pipe and causing to possess plasticity and watertightness together, by a method wherein the tip of the faucet short pipe is pressure-contacted directly to the fringe part of a fitting port provided in the original pipe through a rubber ring. CONSTITUTION:A fitting port 11A is bored into an original pipe 11 and a rib 11C around the fitting port 11A of the original pipe 11 is removed. The fringe part of the fitting part 11A is clothed with a rubber ring 13. A processing mold 15 is inserted into the original pipe 11. The tip of a faucet short pipe 12 is softened by heating, pressed into the rubber ring 13 by a press machine and the tip of the faucet short pipe 12 is pressure-contacted with the fringe part of the fitting port 11A by a processing mold 15 so that the rubber ring 13 is wrapped in the processing mold 15. With this construction, the tip of the faucet short pipe 12 is pressure-contacted directly with the fringe part of the fitting part 11A provided in the original pipe 11 and fitting strength can be improved. Since the tip of the faucet short pipe 12 is pressure-contacted with the fitting port 11A of the original pipe 11, plasticity and watertightness can be caused to possess together. |
