Abstract
The pipe fitting interlocking system includes a central body of predetermined configuration, for example, ell, wye or tee shape of desired large diameter pipe size. The central body terminates at each of its ends in a lock junction to receive thereon in locked relationship an end hub member of the type suitable for receiving and interconnecting the spigot end of a section of plastic pipe. Each lock junction includes a shoulder upon which the end hub member is seated, an endwardly positioned lock and a circular, peripheral recess positioned between the shoulder and the lock. The end hub member includes a radially inwardly inclined projection to cooperate with and securely seat within the central 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. The gasket includes a grooved base and a circular apex spaced from the base a sufficient distance to press and deform against an interior peripheral portion of a hub member.
