ABSTRACT:
An apparatus for expanding an end portion of a tube positioned within an opening defined by an outer member is disclosed. Such apparatus comprises a generally elongated first housing having one end portion adapted to be inserted into the tube including a plurality of rollers, mounted in the housing for expanding the end portion of the tube outwardly in engaged relation with peripheral portions of the outer member forming the opening and for developing forces directed axially into the tube. A mandrel having a taper opposite that of the rollers is positioned therebetween and inserted in the first housing to operatively cooperate with the rollers to outwardly expand the tube and develop generally axial and inward forces. A second housing is adapted to be securedly positioned along pre-selected locations of the first housing and having at least a first open end portion which faces the outer member and the end portion of the tube. A reversible collar member having first and second free end portions is adapted to be removably positioned within the opening of the second housing in at least one of two positions. In the first position, the first free end portion is configured to be engaged at least with the outer member in a manner to permit the tubular member to be expanded so as to extend a predetermined distance outwardly of the outer member. In the second position, the second free end portion is configured to be engaged at least with the outer member to retain the end of the tube substantially continuous with surface portions of the outer member.
