ABSTRACT:
Apparatus for testing the impermeability to gases of connections between pieces of piping, especially between pipes and sleeves, utilizes tow elastic sealing bodies that are spaced apart from each other. The sealing bodies can be pressed against the surfaces of the pipes in response to the application of axial stresses to thus confine the testing location which is to be monitored. The first sealing body is located in the pipe inwardly of the testing location and is adapted to be pressed from within against the surface of the pipe, and the second sealing body can be pressed against the periphery of the sleeve. This renders it possible to test, already within the manufacturing plant, even short pieces of piping for impermeability to leaks.
