Precautions
1. Insertion of the tube
(1)
Cut the tube perpendicularly, being careful not to damage the external surface. Use SMC’s tube cutter
TK-1, 2 or 3 for cutting. Do not cut the tube with pliers, nippers, scissors, etc. If the tube is cut by any tools
other than a tube cutter, the cut surface of the tube will be slanted or flat, making it difficult to be connected
securely, causing the tube to come off or air leakage after the tube is connected. Also, allow a sufficient
margin of tube length.
(2) Hold the tube and push it in slowly, inserting it securely all the way into the fitting.
(3) After inserting the tubing, pull on it gently to confirm that it will not come out. If it is not installed securely all
the way into the fitting, problems such as leakage or disconnection of the tube can occur.
2. Removal of the tube
(1) Push the release button flange evenly and sufficiently to release the tube. Do not push in the tubing before
pressing the release button.
(2) Hold down the release button while pulling out the tube. If the release button is not held down fully, it will be
more difficult to pull out the tube.
(3) If the removed tubing is to be used again, cut off the section of the tubing which has been gripped.
Re-using the gripped portion of the tube can cause problems such as air leakage or difficulty in removing
the tube.
3. Other manufacturers' tubes
If tubes of brands other than SMC are used, confirm that the materials and tolerance of the tubing outside
diameter will satisfy the following specifications.
(1) Nylon tube: Within ±0.1 mm
(2) Soft nylon tube: Within ±0.1 mm
(3) Soft polyurethane tube: 0.15 mm, within -0.2 mm
Do not use tubing which does not meet these outside diameter tolerances.
It may not be possible to connect them, or they may cause other trouble, such as air leakage or the tube pulling
out after connection.
