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.

A fitting assembly for maintaining a leak free seal connection with an associated fluid conduit during and after exposure to extreme heat is provided. The fitting assembly includes a coupling body including an inside surface defining a bore for receiving the associated fluid conduit. The coupling body is made of a first corrosion resistant material having a first coefficient of thermal expansion. The at least one ring is made of a complementary second corrosion resistant material having a second larger coefficient of thermal expansion such that the second material will expand at a greater rate that the first material during heating to a first temperature generally exceeding annealing temperatures of both the first material and the second material. The second material contracts at a greater rate that the first material during subsequent cooling to a second temperature below the annealing temperatures thereby restoring compressive and tensile stresses in the associated fluid conduit and the fitting assembly for ensuring that the fitting assembly maintains a leak free seal connection with the associated fluid conduit.
