ABSTRACT OF THE DISCLOSURE An explosive activated tube plug for effecting a mechanical seal within a tube is disclosed. The plug includes an internally tapered expansion sleeve, a frusto-conical piston disposed within the sleeve and an extension member to expedite plug placement. By remotely detonating an explosive disposed within the plug, the piston is driven forward to expand the sleeve against the surrounding tube surface. By modifying the physical structure of the plug, the energy-displacement relation- ship between the piston and sleeve may be selectively controlled.
