Abstract
A pipe branch fitting has a cylindrical body freely slidable along the pipe to a point where a hole is pre-cut in the pipe. On one side, the cylinder carries a screw-threaded tubular insert on which the branch is to be connected. A gasket between the insert and the pipe gives a seal as the insert bears upon it as the insert is tightened up. The inner end of the insert has a stepped shoulder which abuts the periphery of the hole in the pipe and limits the compression applied to the gasket. The reduced diameter end of the insert locates itself in the hole and indicates if the fitting is misaligned with the hole.
