Abstract: The multi-seal tube plug comprises a substantially cylindrical sheath closed at one end and having a central cavity. An expander is received within the central cavity of the sheath and acts to expand the sheath into contact with the tube. The expander comprises a plurality of radially expandable disks having a central aperture and an expander member adapted to be received within the aperture and to expand the disks. The expanded disks expand a portion of the sheath into contact with the tube to sealingly engage the tube. The expander member is preferably conical and interacts with the conical inner surfaces of the disks. An alternate embodiment of the multi-seal tube plug uses conical washers rather than radially expandable flat disks. All embodiments of the multi-seal tube plug are easily removable and do not damage the tube.
