Abstract: A pair of compressible seals having a relaxed diameter which permits insertion through a sleeve which has been installed in a tube are empolyed. After installation, which respectively positions the seals beyond and adjacent the opposite ends a repair sleeve, an actuator is employed to apply an axial compressive force to one of the seals. The force is transmitted via the first seal to the second so that both seals will, as a result of their axial compression, expand outwardly to establish fluid tight seals with the tube wall. The area between the seals is then pressurised, for example with helium gas, and a test for leakage of the helium performed.
