ABSTRACT:
A tool to be mounted to smooth wall tubes. The tool has an entry for the tube end, a split collet member cooperating with an annular seal within the tool, and a piston or ram element which is translated to sealing by fluid pressure acting on the piston element. This force provided by the piston element causes the split collet to engage the tube and to provide the force necessary to compress the seal around the tube. The tool may be provided as a dead head, or may be coupled to a second conduit for conveying fluids therethrough.
