A swaging tool for use in swaging axially swaged fittings for joining together pipes. The present invention provides a radially balanced axial force, for uniformly pushing a ring of an axially swaged fitting over a sleeve, to swage the fitting to the pipe. The swaging tool of the present invention includes a tubular housing, having an inner surface, which defines a bore. The bore is configured to receive a pipe section having an axially swaged fitting placed thereon in preparation for swaging. Preferably, the housing may be split lengthwise into two opposed sections, such that when the two sections are brought together, the sections completely surround a portion of the pipe section and the fitting. Each housing section is provided a plurality of pusher assemblies, each pusher assembly may preferably be connected to a source of hydraulic pressure, which when activated moves the pusher assembly axially to provide the axial force necessary for swaging the fitting. Each pusher assembly is made to uniformly contact the ring with a substantially equal amount of force, such that the ring is moved axially over the sleeve, which causes a radial force to be applied to the sleeve to swage the sleeve to the pipe section.
