ABSTRACT:
A coupling assembly includes a first pipe having a threaded portion and a non-threaded portion and a second pipe having a threaded and non-threaded portion. The non-threaded portion of each of the pipes is located at a free end of the first pipe and the second pipe. The coupling assembly also includes a coupling member for fixedly connecting the first pipe and the second pipe. The coupling member includes a first threaded inlet for receiving the first pipe, a second threaded inlet for receiving the second pipe and a non-threaded portion extending between the first inlet and the second inlet. The non-threaded portion of the coupling member includes an annular recess. A cross-section of the annular recess includes a vertical leg, a first angled leg extending from the vertical leg, a horizontal leg extending from the first angled leg, a second angled leg extending from the horizontal leg and a third angled leg extending from the second angled leg to the first threaded inlet of the coupling member.
