Abstract: A swaging tool for swaging fittings and joining separate tubes together. The swaging tool includes a removable head assembly having a head member and a first spring clip adapted to retain a first die to a portion of the head member. The head assembly includes a die block and a second spring clip adapted to retain a second die to a portion of the die block. The swaging tool includes a power unit assembly having a base member adapted to receive the die block and head member of the head assembly. The power unit assembly includes a moveable piston adapted to engage the die block so as to move the second die towards the first die during a swaging operation.

Abstract: An axial swaging tool including a housing defining a chamber, a piston rod held statically in the chamber, a piston conformingly receiving and slidable along the piston rod, a ram conformingly receiving and slidable on a first end of the piston rod, a first engagement member statically positioned on the housing, a second engagement member positioned on the piston, and a spring adjoining the piston and an end of the piston rod. The spring is configured to bias the piston away from a second end of the piston rod, such that the second engagement member is biased away from the first engagement member, the piston rod is biased against a first end of the housing, and piston is biased against the ram, which in turn is biased against a second end of the housing.
