ABSTRACT:
A compact apparatus for crimping a fitting onto an elongated member is provided which has a cylindrical housing, a tubular piston in the housing providing a central passageway to receive the elongated member and a fitting, a plurality of crimping dies moving radially together and apart which are actuated by the tubular piston, fluid means for moving the tubular piston longitudinally in a forward direction and springs for retracting it, and mounting means for the cylindrical housing. The apparatus contains an improved housing and piston structure, means for positioning the elongated member and fitting between the crimping dies, and means to automatically stop the longitudinal movement of the piston at a predetermined position.
