Abstract
A process and apparatus for joining a tube into a tube sheet opening. After a tube is inserted into a tube sheet opening, compression and subsequent radial expansion of an elastomeric material inside the tube causes the elastomer to radially expand the tube wall creating an interference fit between the tube and inner wall of the tube sheet opening. A portion of the elastomer positioned exterior to the tube sheet face expands to a greater radial diameter than the portion of the elastomer within the tube sheet opening resulting in radial expansion of the tube wall toward the tube sheet face to create a sealing effect between the tube and tube sheet.
