Abstract: A heat exchange plug that plugs the aperture of a tubesheet with a leaking tube while also securing the tube against movement that could damage other tubes of the tubesheet. A cylindrical housing member with two different diameter body section can be inserted so that the wider diameter section is positioned in the aperture of the tubesheet and the smaller diameter section is located in the tube. An eccentric ring at the end of the housing member can engage the tube and prevent rotation as an insert member is advanced into the rear of the housing member via a threaded shank of the insert member that engages a threaded inner bore of the housing member. A ramped surface of the housing member deforms the wall of the larger diameter section of the housing member outwardly to plug the aperture while the smaller diameter section secures the tube in place.
