ABSTRACT OF THE DISCLOSURE A novel pipe fitting construction is provided herein. The pipe fitting includes a center body of predetermined configuration, for example, wye or tee shape, of desired pipe size. The center body terminates at each of its ends in a lock junction to receive thereon in locked relation- ship an end hub of the type suitable for receiving and interconnecting the spigot end of a length of plastic pipe. Each lock junction includes a shoulder upon which the end hub is seated, an endwardly positioned lock and a circular, peripheral recess positioned between the shoulder and the lock. The end hub includes an inwardly inclined projection to cooperate with and securely seat within the center body lock. A circular gasket is secured within the circular recess and biases against a portion of the inner periphery of the end hub to prevent leakage between the parts. This pipe fitting construction technique seeks to overcome the time consuming, costly and frequest quality control problems of the prior art pipe fitting techniques.
