PROBLEM TO BE SOLVED: To provide a pipe fixing structure for multi-position selector valve having elastic function in which processing and fitting can be easily carried out.SOLUTION: This invention discloses a pipe junction part comprising an elongated pipe member 21, elastic ferrule device 24 and support ring 30 arranged around the elastic ferrule device 24. The elastic ferrule device 24 has a cup-shaped receiving recess 36 having such a size as one receiving the pipe member 21. The pipe junction further has a cap member 31 including an outer face, an inner face opposite to the outer face and a passing pipe accepting passage 35. Upon fitting of the cap member 31 to a valve device, the support ring 30 and the ferrule device 24 are compressed by the cup-shaped receiving recess 36 to form a fluid tight seal between a pipe opening 22 and a communication port 45 of the valve device. |
