Abstract
A tubular connector system is disclosed for joining two pipe ends without the necessity of rotating the pipe ends. One pipe end is provided with an external thread and a second pipe end includes multiple thread lead entries. The tubular connector includes an internal thread at one end and internal multiple thread lead entries at the other end. The tubular connector is first threaded onto the first pipe. Next, the second pipe is stabbed into the second end of the tubular connector and the tubular connector is then rotated less than a single turn with respect to the second pipe to fully mate the tubular connector and the second pipe. In a preferred embodiment of the present invention the tubular connector is provided with resilient seals and a slot and tab arrangement to restrict rotation after make-up.
