062 MINSTAC - Tube Fitting Assembly Instructions & Part Numbers

The 062 MINSTAC fitting system is for use with 0.062" (1.57 mm) O.D. Teflon® tubing and uses a 0.138-40 UNF fitting end. This system utilizes an internally threaded Collet that grips the outer diameter of the Teflon® tubing end, preventing cold flow. The Coupling Screw acts like a compression fitting and presses the chamfered end of the tubing against one end of the KEL-F® Ferrule. The other end of the Ferrule is pressed against the sealing surface in the boss by the Coupling Screw.

062 MINSTAC Fitting Assembly Procedure


1. Cut the tubing to the desired length with a sharp blade. Be careful not to pinch tubing. Pinching cutters are not recommended. The cut should be reasonably square.

2. Slide the Coupling Screw (part no. TMAA320207?Z) over the end of the tubing, knurled end first. Place the Collet (part number TMCA3202030Z) into the Lee Collet Tool (part no. *TTTA3201443A) counterbore end first.


* The Lee Collet Tool TTTA3201443A is for use with 0.032" (0.81 mm) I.D. tubing. The following tools should be substituted for use with their respective sized tubing:

TTTA3201743A - 0.012" (0.30 mm) I.D. tubing
TTTA4000143A - 0.040" (1.02 mm) I.D. tubing

3. While holding the tubing with the rubber Tubing Grip, screw the Collet onto the tubing end. This should require about 15-20 turns (right hand thread) of the Collet Tool. Remove the tool from the Collet and check that the Teflon® tubing extends at least to the end of the Collet.


4. Using the Lee Chamfering Tool (part number *TTTA3201543A), place the pilot pin into the tube. Rotate the tool in a clockwise direction while applying a small axial force until it bottoms out against the Collet (already installed on the tubing). This cuts the tubing to form the sealing chamfer.


* The Chamfer Tool TTTA3201543A is for use with 0.032" (0.81 mm) I.D. tubing. The following tools should be substituted for use with their respective sized tubing:

TTTA3201643A - 0.012"
(0.30 mm) I.D. tubing

TTTA4000243A - 0.040"
(1.02 mm) I.D. tubing

5. Slide the Coupling Screw over the Collet.

6. Push the large end of the Ferrule (part number TMBA3202910Z) onto the Ferrule Installation end of the Lee Chamfer Tool (part number TTTA3201543A).


7. While holding the Coupling Screw, insert the Ferrule into the Coupling Screw (approx. 4 lbs. (1.8 kg.) force is required). The Ferrule will “snap” in place. The coupling assembly is now complete.
