Abstract
An improved pipe branch fitting for use with a pipe having a pre-cut hole is disclosed. The branch fitting has a cylindrical body freely slidable along the pipe to a point where the hole is pre-cut. On one side, the cylindrical body carries an internally threaded boss into which a modified sprinkler head may be threaded. A gasket positioned between the sprinkler head and the pipe gives the seal as the sprinkler head bears upon the gasket upon tightening of the sprinkler head. The inner end of the modified sprinkler head has a stepped shoulder which abuts the periphery of the hole in the pipe and limits compression applied to the gasket. A reduced diameter end portion of the modified sprinkler head locates itself in the hole and indicates if the fitting is misaligned with the hole. The end walls of the body are each tapered toward the boss to facilitate the sliding of the cylindrical body, when assembled on the pipe are supporting structures of a building in which the piping system is being installed.
