Abstract
An expansion tool includes a working element configured to expand an end of a tube. The working element includes a plurality of jaws movable between a closed position and an expanded position. The expansion tool also includes first mandrel with a first contact surface and a second mandrel coupled to the first mandrel. The second mandrel has a second contact surface. The first mandrel and the second mandrel are movable together relative to the jaws between a retracted position and an extended position. The first contact surface and the second contact surface are engageable with the jaws to move the jaws from the closed position toward the expanded position in response to movement of the first mandrel and the second mandrel from the retracted position toward the extended position.
