Abstract
A hydraulic installation tool comprises a fixed jaw, a movable, and a plurality of independent hydraulic cylinders each comprising a piston. Movement of the pistons in a first direction moves the movable jaw toward the fixed jaw. A plurality of guide rods comprises a first end secured to the fixed jaw. A plurality of retaining members are each removably coupled to an associated one of the plurality of guide rods about the second end. The movable jaw is disposed between the fixed jaw and the plurality of hydraulic cylinders for movement along the guide rods. Each hydraulic cylinder is independently removable from the associated guide rod upon removal of the associated retaining member from said guide rod. In one example, the fixed and movable jaws are configured to engage and axially force a swage ring onto a fitting body to connect and seal the fitting body to a fluid conduit.
