<p>PROBLEM TO BE SOLVED: To provide a pipe connection joint capable of firmly and simply interconnecting pipes different in standard. SOLUTION: In an integrally formed joint having two or more connection ports, at least one of the connection ports is formed based on the outside size of a pipe having standard different from that of other connection port. Since at least one of the connection ports of an integrally formed fitting is formed based on the outside diameter size of a pipe having a standard different from that of the other connection port, no part being unstable in terms of strength is present and firm connection is practicable. Further, since it is sufficiently well that only connection between a pipe and a fitting is effected, execution is simple to make and a cost required for connection of a pipe is also reduced.</p> |
