A method of providing a pressure test on a tube to identify leakage includes the steps of (a) mounting a clamp on a tube adjacent an end and such that a plug which is part of the tool is positioned to plug an inlet into the tube, (b) actuating the tool to cause the plug to provide a fluid tight seal in the inlet, and (c) applying a source of pressure to the tube, and monitoring the pressure within the tube, and identifying a leak should the pressure drop more than a predetermined amount in a particular period of time. A tool for use in providing a seal on a tube end to allow a pressure test is also disclosed.
