ABSTRACT:
Tool includes a fixed handle and a movable, lockable handle. A working end of the tool includes an upper jaw and a movable lower jaw. A passage may be provided in one or both of upper and lower jaws. A sealing device may be provided in the upper jaw, the sealing device being disposed adjacent to the passage. Lower jaw may likewise include a passage therein. In use, an elongated object such as a tube may be inserted into the passage in the lower jaw and then into the passage in the upper jaw adjacent the sealing device. When the lower jaw is engaged with the upper jaw, the lower jaw compresses the sealing device and sealingly engages the sealing device, the passage, and the tube disposed therein. In that manner, a seal is achieved. In the case where an opening having a coupling is fluidly connected to the upper jaw, a sealed, fluid connection may be established between the coupling on the upper jaw and the tube engaged by the seal.
