ABSTRACT:
A laboratory tool for repairing connections for tubular elements and tubing by stripping the ferrule from the end of the laboratory tubing without damaging the tubing. The tool is designed to accommodate a plurality of tubing sizes, and includes a pliers-like instrument having posts projecting from one jaw, each post corresponding in diameter to the mean diameter of the tubing. The other jaw of the tool is slotted to accommodate the outside diameter of the tubing. The posts are arranged in series on one jaw with the largest diameter post being outermost and the slot in the opposite jaw has its greatest width adapted to register with the largest post. Each successively smaller post is positioned closer to the pivot of the jaws but with sufficient clearance from the previous post to permit a ferrule to slide over the post. In operation, the tool is engaged on opposite sides of the ferrule positioned in the tubing with the post in registry with the end of the tubing and the slot receiving the tubing on the opposite side of the ferrule. Closing the jaws then engages the marginal edges of the slot with the rearwardly-facing portion of the ferrule and permits the ferrule to be disengaged forwardly from the tubing. The disengagement of the ferrule from the tubing permits the tubing to be furnished with a fresh ferrule for reuse.
