Abstract
The assembly of a connection that uses cooperating grooved surfaces to provide an easily disassembled and assembled connection is improved by the use of a centering surface and cooperating lip that engages the faces of the connection end to prevent lateral misalignment while the pipe ends are brought together for axial alignment. The centering device may be used with a clamping mechanism to provide single person assembly of this type of connection despite normal field misalignments. The centering surface in the face of the connection ends may use any type of gasketing surface to provide the desired amount of seal strength.
