ABSTRACT:
A seal ring socket is disclosed having a ball ring at an insert end which rolls up on a socket neck portion when an insertion pipe is pushed into the ring socket. The rolling of the ball ring expands its volume to insure a water-tight seal against the insertion pipe. Grooves formed in a socket neck portion cause unbalanced stressing of the interior and exterior surfaces of the ring socket thereby assisting in the rolling of the ball ring.
