Concentricity adjustment sleeve

A device for adjusting the position and concentricity of a die subassembly relative to a central axial tip, the device comprising:

• a die body assembly including the central axial tip;
• a die subassembly positioned adjacent and in contact with the die body assembly, the die subassembly comprising:
• a retaining device to connect the die subassembly to the die body assembly;
• an adjustment sleeve subassembly including an adjustment sleeve circumferentially positioned adjacent the die subassembly and rotationally movable relative thereto;
• and
• an adjustment device connected to the adjustment sleeve at a fixed position thereon, the adjustment device being radially movable relative to the die subassembly and in contact with the die subassembly,
• wherein the adjustment device is capable of any degree of rotation relative to the die subassembly by rotating the adjustment sleeve relative to the die body and the die subassembly to thereby adjust the concentricity of the die subassembly relative to the die body assembly and the central axial tip thereof while maintaining the retaining device tightened sufficiently to prevent leakage between the die subassembly and the die body assembly.
