Refer to front matter 56 for Safety Instructions, pages 13 to 16 for Fittings and Tubing Precautions. Selection Warning 1. Make sure to confirm the specifications. Do not use with pressures or temperatures outside the range of specifications, as this may result in damage and malfunction. (Refer to the specifications on page 188.) SMC takes no responsibility for damage incurred by use in excess of the specification range. 2. Prohibition of disassembly and modification Do not disassemble or modify (including additional machining) the main body. False use may cause an injury or accident. 3. Confirm that PTFE can be used in application. Thread sealant contains PTFE (polytetrafluoroethylene) powder. Confirm if the use of it may cause any adverse effect on the system. 4. Cannot be used as a stop valve that requires zero leakage. A certain amount of leakage is allowed during operation. 5. Refer to the table below for whether the S coupler can be connected. When the KK130 series is connected to other companies’ products, confirm manufacturers and other information before using it. Caution 1. When connecting the plug to the socket, select the series suitable for the connection. If the series are not matched, they cannot be connected. Mismatches will cause leakage, damage, and disconnection of the plug. Inserting a plug other than the specialized plug into the socket may result in equipment damage. 2. Do not rotate or turn the S coupler and piping to which it is connected. The connection of the piping might be damaged or come undone. 3. Do not use couplers with flammable, explosive, or toxic substances, such as gas, gas fuel, and refrigerant. They may leak from the S coupler or from inside the tubing to the outside. 4. Operate with a surge pressure of no more than the maximum operating pressure. If the surge pressure exceeds the maximum operating pressure, it will cause damage to couplers and tubing. 5. Do not use the S coupler with water or steam. Corrosion of the metal material and deterioration of the sealing material may result from long-term use with water or steam. 6. The tube bending radius in the vicinity of the fitting should be at least the minimum bending radius of the tube. If the bending radius is less than the minimum value, fittings may damage, or tube may crack or be crushed. The minimum bending radius, with the exception of TU polyurethane tube, TUH hard polyurethane tube, TUS soft polyurethane tube, TRBU FR double layer polyurethane tube, TH FEP tube, TL PFA tube, TD modified PTFE tube, is measured as following in accordance with JIS B 8381-1995. Tube deformation ratio at the minimum bending radius is obtained through the following formula, based on tube diameter and mandrel diameter by wrapping the same radius mandrel tube. 7. Applicable for air. Consult with SMC if using other fluids. 1. Instruction manual Mount and operate the product after reading the instruction manual carefully and understanding its contents. Also, keep the manual where it can be referred to as necessary. 2. Ensure sufficient space for maintenance. Be sure to allow the space required for maintenance and inspection. 3. Tightening torque When installing the products, tighten the screw with the recommended tightening torque. 4. During use, pipe deterioration or damage to S couplers can result in disconnection of the piping and uncontrollable behavior of the piping. To stop the piping from going out of control, use a protective cover or fix the piping in place. 5. Do not use couplers where rotation normally occurs. The couplers may be damaged. 6. Avoid applications in which vibration or shock is directly applied to the fittings. When mounting the S coupler to a piece of equipment that generates impact or vibration, do not connect the S coupler to the equipment directly. In that case, connect a hose whose length is 300 mm or more between the S couplers. Mounting Warning 193 KQ2 KQB2 KS KX KM KF M H/DL L/LL KC KK KK130 DM KDM KB KR KA KQG2 KG KFG2 MS KKA KP LQ MQR T
