Abstract:
1. A handheld hydraulic assembly tool for advancing a fitting's swage ring onto a fitting's connector body while a conduit is received in the connector body to mechanically and sealingly connect the fitting to the conduit, said hydraulic assembly tool comprising: a clamping assembly defining a piston chamber hoselessly fluidly connected to a pump chamber so as to form a compact assembly tool, said clamping assembly having a fixed jaw engaged with one of the connector body or the swage ring and a moveable jaw engaged with the other of the connector body or the swage ring, said fixed and movable jaws configured to engage and axially force the swage ring onto the connector body to connect and seal the connector body to the conduit received therein; a piston disposed in said piston chamber; said piston and said moveable jaw configured such that movement of said piston in a first direction moves said moveable jaw toward said fixed jaw thereby moving the swage ring axially onto the connector body to mechanically and sealingly connect the connector body to the conduit received therein when the jaws are engaged to the connector body and the swage ring; a pump body defining said pump chamber, said pump body connected to the clamping assembly in close proximity thereto to form a compact handheld tool; a fluid reservoir fluidly connected to said pump chamber; and a manually-operated pump piston disposed in said pump chamber for drawing hydraulic fluid from said fluid reservoir and forcing said hydraulic fluid into said piston chamber to move said piston in said first direction.
