Abstract
A novel tube plug which may be used to plug selected tubes in a heat exchanger has a cap portion for substantially closing a heat exchanger tube and a tube engaging portion depending from the cap portion, for insertion into the tube to retain the tube plug. By applying solder to the tube plug, the tube is sealed off, without providing a large solder mass which could cause damage due to thermal stresses.
