<p>PROBLEM TO BE SOLVED: To improve reliability of connection by using a pipe fitting and to facilitate connecting work by providing the pipe fitting facilitating connection of different diameter pipes. SOLUTION: This fitting is furnished with a large diametrical connecting part 4, a small diametrical connecting part 5 and a communicating part on a fitting main body 2 formed of a flexible material of rubber, etc., and connects different diameter pipes (large diametrical pipe, small diametrical pipe). A bathtub side pipe (circulation pipe) made of a large diametrical pipe and a hot water supply side pipe (circulation pipe) made of a small diametrical pipe are communicated to each other by using this pipe fitting. Consequently, it is possible to facilitate connection of the different diameter pipes, to improve reliability of connection and to simplify connecting work.</p> |
