Selection Mounting Warning Caution 1. Check the specifications. Give careful consideration to operating conditions such as the application, fluid and environment, and use within the operating ranges specified in this catalog. Tube may burst or lead to operation failure if operating conditions are out of the specification range. The specifications of the catalog are designed assuming the product is used with the fixed conditions. 2. When using the product for medical care This product is designed for use with compressed fluid system applications for medical care purposes. Do not use in contact with human bodily fluids, body tissues or transfer applications to a human living body. 3. Maintenance Perform periodic maintenance inspections, securing enough space for maintenance. 4. Countermeasures for static electricity Since static electricity may be generated depending on the fluid being used, implement suitable countermeasures. 7. Mount so that tubing is not damaged due to tangling and abrasion. This can cause flattening, bursting or disconnection of tubing, etc. If the LQ1 or LQ3 fitting is used, connect the tube with the specialized tool. Refer to the pamphlet “High-Purity Fluoropolymer Fittings HYPER FITTING/Series LQ1, 2 Work Procedure Instructions” (M-E05-1) or “High Purity Fluoropolymer Fittings Hyper Fitting / Flare Type Series LQ3 Fitting Procedure” (M-E06-4) for connecting tubing and special tools. (Downloadable from our website) Maintenance Caution 1. Check the following after the initial installation and for each periodic inspection. If any problem is confirmed, replace the tube with a new product or reconsider the customer's operating conditions. a) Cracks, gouges, wearing, corrosion b) Leakage, penetration, dissolution c) Twists or crushing of tubing d) Hardening, deterioration, softening of tubing . There may be plasticizer (white powder) deposits on the surface of the tube, but there is no impact on performance. 2. The two layers of the tube are completely bonded. If separation is confirmed between them, replace the tube with a new one or reconsider the customer’s operating conditions. 3. If the tube and the fitting are removed or replaced, eliminate the residual fluid with air or water. 4. When using insert, miniature or fluoropolymer fittings over a long period, some leakage may occur due to age deterioration of the materials. If any leakage is detected, correct the problem by additional tightening. If tightening becomes ineffective, replace the fittings with a new product immediately. 5. Do not repair or patch the replaced tubing or fittings for reuse. Operating Environment Warning 1. Do not use in locations having an explosive atmosphere. 2. When vibration or impact is applied, make sure to test in the same environment as the actual operating environment, and confirm that no problem will occur in the operating conditions. 3. In locations near heat sources, block off radiated heat. Mounting Caution 1. Check the model number, size, etc. before installing. Check tubing for damage, gouges, cracks, etc. 2. Before piping, perform air blow (flushing) or cleaning to remove any dust, etc. from the piping. 3. There may be plasticizer (white powder) deposits on the surface of the tube, but there is no impact on performance. 4. Cut the tube perpendicularly using a tube cutter. If the tube is cut incorrectly, fluid can leak or the tube can fall out as a result. 5. When connecting tubing, allow a sufficient margin considering the change of tube diameter and length due to pressure. 6. Do not apply unnecessary forces such as twisting, pulling, moment loads on fittings or tubing. It may cause leakage, the fitting to fracture or the tube to be crushed, burst or fall off. Caution 1. When toxic solvent is used, make sure to test in the same environment as the actual operating environment, and confirm that no problem will occur in the operating conditions. 2. When the joint of the tube or fitting rotates, make sure to test it in the same environment as the actual operating environment, and confirm that no problems will occur in the operating conditions. 3. The surge pressure must not exceed the maximum operating pressure. 4. There may be plasticizer (white powder) deposits on the external surface of the tube. Please be careful when the tube is used in clean rooms. Otherwise, the clean level may decrease. 5. If fittings of brands other than SMC are used, be sure to confirm that no problem will occur with the operating conditions. 6. Trademark, product number, the material of inner/ outer layer, O.D. x I.D. size, production lot number, and country of origin are printed in 500 mm intervals on the outer surface of the tube. Printed letters may be erased depending on fluid. Series TQ Specific Product Precautions Be sure to read before handling.
