<p>PROBLEM TO BE SOLVED: To prevent leakage in a branch pipe joint for connecting a metallic branch pipe to a pipe wall of a main pipe made of synthetic resin. SOLUTION: A joint is a metallic branch pipe joint for connecting a metallic branch pipe 23 to a pipe wall of a main pipe 21 made of synthetic resin, and it is provided with a saddle 22 to be connected to the pipe wall of the main pipe 21, a cylindrical joint main body 25 projecting on the upper surface of the saddle 22, and a packing made of an elastic material to be arranged between the saddle 22 and the main pipe 21. Contact pressure of the packing in relation to the pipe wall of the main pipe 21 is so constituted as to be decreased toward the inner periphery of the packing.</p> |
