ABSTRACT:
A swaging tool is provided for swaging a fitting and joining two tubes together, especially fittings in difficult-to-access areas. A removable head of the tool holds a first die stationary with respect to a second die moved toward the first die by a double piston arrangement within the tool cylinder. The head is slideably removable directly from the cylinder by a tongue and groove configuration on the head and cylinder, respectively, which further includes head alignment means to ensure proper orientation of the dies. Additional die aligning features are provided, as well as other features, including means for recognizing tool wear, an improved return spring for retracting the pistons, tool insertion guides to facilitate assembly of the tool and other features which result in an extremely compact and lightweight tool.
