ABSTRACT:
A hydraulic chuck having a piston means with an axially centered passage, the first end of which has a tube seating means associated therewith for engaging a tube. Collet means are provided and located at the first end of the piston means for engagement of the tube upon closure of the collet means. Biasing means operably connected to the piston means for normally forcing the surface means upon the collet means are also provided. Sealing means adjacent to tube feeding means for sealing the tube to the chuck, including seal seat means adjacent to collets and positioned to compress the seal radially inward under pressure of the biasing means, are provided. Finally, the handle or attachment means is provided to operably connect to the biasing means to remove the surface means from the collet means, thereby releasing the radially inward compression of the sealing means and permitting insertion of the tube.
