ABSTRACT:
A body is provided with longitudinally spaced first and second annular grooves for receiving first and second longitudinally spaced annularly spaced seal and lock ring segment assemblies therein to sealingly engage and lock with a pipe coupling and a single pipe end engaged therewith for forming a fluid receiving test chamber that extends across the single connection between the pipe end and the coupling. A fluid passage in the body conducts fluid to move said first and second seal and lock ring segment assemblies into sealing and locking engagement with the pipe and coupling, respectively, to form the fluid receiving test chamber. A second passage conducts fluid to the chamber for testing the single connection between the members from inside the members to the exterior thereof through the single connection. A leak in the connection is determined by instrumentally noting a pressure drop in the chamber or by visually noting leakage of fluid at the connected pipe coupling end.
