Abstract

A saddle wye for connecting a branch pipe to a heat fusible thermoplastic main pipe, including a heat fusible thermoplastic saddle shaped and adapted to be received on the main pipe. The saddle includes top and bottom surfaces and an opening extending between the top and bottom surfaces for alignment with an opening in the main pipe. A branch extension extends at an acute angle from the top surface of the saddle such that a first open end of the branch extension is connected the opening of the saddle and a second open end of the branch extension extends above an end of the saddle. A resistance heating wire is secured to the bottom surface of the saddle around the opening of the saddle in a pattern that includes a parabola. The wire pattern assures that fusion occurs close to the opening in the saddle to prevent fluid from reaching between the saddle and a sidewall of the main pipe as fluid travels between the branch pipe and the main pipe.
