PROBLEM TO BE SOLVED: To manufacture a pipe fitting at a low cost and high productivity by cutting a long pipe into short pipes, placing eccentrically two short pipes, and closing the crescent-shaped parts formed thereby. SOLUTION: A formed long pipe is cut by a cutter 14 into a plurality of short pipes 15, the short pipe is placed on an inner diameter supporting mold 16, and the short pipe 15' is placed on the same while temporarily eccentrically fixed by a hot melt adhesive material. Then the glass fiber including a hardenable resin is applied by a contact pressure molding method to the crescent-shaped parts formed by shifting the short pipes. After the hardening, one of the crescent-shaped parts is closed by mold releasing, then they are turned over, and the crescent-shaped part of the opposite side is closed. Whereby a pipe fitting connector can be manufactured at a low cost and high productivity.
