Pipe fitting construction |
摘要 |
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 relationship 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.
