Straight section Mounting pitch A Fig. 1 Recommended piping Fig. 2 When using a unifying band to bind together the pipes Recommended NG 1. When using tubing brands other than SMC, confirm that the tube outside diameter tolerances satisfy the following specifications. 1) Nylon tube within ±0.1 mm 2) Soft nylon tube within ±0.1 mm 3) Polyurethane tube within +0.15 mm, within .0.2 mm If the tube O.D. accuracy is satisfactory but measurement of the internal diameter dimensions does not match the dimensions provided by SMC, do not use. The tube may not connect, or leaks, tube disconnection, or damage to fittings may occur. Precautions on Other Tubing Brands Caution Recommended piping conditions 1. When installing piping in the One-touch fitting, make sure there is sufficient slack to the tube length as per the recommended piping conditions shown in Figure 1. Also, when binding pipes together with a unifying band, etc., make sure piping is carried out without receiving external force. (See Fig. 2.)

Do not use in locations where static electric charges will be a problem. This may cause system failure. Consult with SMC regarding use in this kind of environment. 2. Do not use in locations where spatter occurs. There is a danger of spatter causing a fire. Consult with SMC regarding use in this kind of environment. 3. Tube attachment/detachment for One-touch fittings 1) Attaching of tubing (1) Take a tube having no flaws on its periphery and cut it off at a right angle. When cutting the tube, use tube cutters TK-1, 2 or 3. Do not use pinchers, nippers or scissors, etc. If cutting is done with tools other than tube cutters, the tube may become flattened, etc. This can make a secure installation impossible, and cause problems such as the tube pulling out after installation or air leakage. (2) Polyurethane tube O.D. is swelled by applying internal pressure. As such, it may be that the tube cannot be re-inserted into a One-touch fitting. Make sure to confirm the tube O.D., and when the O.D. accuracy is more than +0.07 mm for o2 and +0.15 mm for other sizes, insert into a One-touch fitting again without cutting the tube to use it. When the tube is re-inserted into a One-touch fitting, make sure to confirm that the tube is able to go through the release button smoothly. (3) Grasp the tube and push it in slowly, inserting it securely all the way into the fitting. (4) After inserting the tube, pull on it lightly to confirm that it will not come out. If it is not installed securely all the way into the fitting, this can cause problems such as air leakage or the tube pulling out. 2) Detaching of tubing (1) Push in the release button sufficiently. When doing this, push the collar evenly. (2) Pull out the tube while holding down the release button so that it does not come out. If the release button is not pressed down sufficiently, there will be increased bite on the tube and it will become more difficult to pull it out. (3) When the removed tube is to be used again, cut off the portion which has been chewed before re-using it. If the chewed portion of the tube is used as is, this can cause trouble such as air leakage or difficulty in removing the tube. 4. Connecting products with attached metal rods After attaching products with attached metal rods such as the KC series, to the One-touch fitting, do not use tubes, resin plugs, or reducers, etc. This may cause releasing. 5. When mounting tubes, resin plugs, metal rods etc., do not press the release button. Also, do not press the release button unnecessarily before mounting them. This may cause those parts to come off.
