ABSTRACT:
An assembly tool for tube fittings, including a pair of pivotal manually operated channel-shapped unique leg lever handles which nest one in the other and are provided with a pair of jaws which are connected to the lever handles by a set of low friction rotatable journal shafts, the extremities of the journal shafts being journalled in the lower handles; the journal shafts being positions to maintaine the jaws in parallel relation, while under load, and are provided with coaxial channels to receive the ends of a tube fitting and press the ends of the tube fitting toward each other thereby to cause interengagement of the fitting components; the jaws being readily interchangeable to assemble fittings of a different size or construction. A further embodiment includes a clamp means incorporated in one of the channels to grip a portion of the tube element, the other jaw receiving a flaring (swaging) tool for the clamped tube element.
