ABSTRACT:
A leakage testing apparatus includes a pull bar surrounded by an array of arcuate segments having teeth that engage and deform the inner surface of a tube. When tension is applied to the pull bar, a cam forces the segments to move outwardly to contact the tube while maintaining a parallel relationship to said pull bar.
