• Brass (No plating)
• Brass + Electroless nickel plated Height with multiple usage is uniform. Effective space of height direction Face seal adopted for threading Face seal Sealant Re-piping is possible. Face seal Repeated re-piping some 6 to 10 times is possible due to use of elastic sealant on seating. Sealant Sealant tape is necessary because sealant becomes separated with repeated installation. Prevention of sealant residue/protrusion Existing sealant type leaves residue and protrudes out from the threading when installing, making it necessary to clear away the residue using an air blower or similar. However, no residue is created when using a face seal.

connection. Possible to use in vacuum to –100 kPa Seal Stud Release button (Light gray) O-ring Body Release button (Light gray) Body Chuck Guide Chuck Guide Seal M, R, Rc Connection thread Suitable for use with nylon and urethane. Large retaining force. The chuck provides secure retention and the collet increases the holding force on the tube. Requires little force for removal. Releases the chuck collet to remove the tube as well as to prevent the chuck from biting too deeply into the tubing. Effective when piping in a confined space. Body part rotates allowing for positioning. Can be used for a wide range of pressures from a low vacuum up to a pressure of 1 MPa. The use of a special profile ensures sealing and reduces resistance when the tube is inserted. * Fittings with all resin body material (KQ2 - A) are copper free specification. Made to Order Specifications (Refer to page 31 for details.) Specifications Note 1) The surge pressure must be under the maximum operating pressure. Note 2) Do not use the fittings with a leak tester or for vacuum retention because they are not guaranteed for zero leakage.

connection. Possible to use in vacuum to −100 kPa Seal Stud Release button (Orange) O-ring Body Release button (Orange) Body Chuck Guide Chuck Guide Seal UNF, NPT Connection thread Suitable for use with nylon and urethane. Large retaining force. The chuck provides secure retention and the collet increases the holding force on the tube. Can be used for a wide range of pressures from a low vacuum up to a pressure of 1 MPa. The use of a special profile ensures sealing and reduces resistance when the tube is inserted. Requires little force for removal. Releases the chuck collet to remove the tube as well as to prevent the chuck from biting too deeply into the tubing. Effective when piping in a confined space. Body part rotates allowing for positioning. * Fittings with all resin body material (KQ2 - A) are copper free specification. Made to Order Specifications (Refer to page 56 for details.)

Sealant tapeExpose approx. 1 thread 1. Preparation before piping Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe. 2. Wrapping of sealant tape When screwing together pipes and fittings, etc., be certain that chips from the pipe threads and sealant does not get inside the pipe. Also, when the sealant tape is used, leave approx. 1 thread ridges exposed at the end of the threads. 3. Check the model, type and size before installation. Also, confirm that there is no scratches, gouges or cracks on the product. 4. When connect ing the tubing, take pressure or possible changes to the tubing length into account, and allow a sufficient margin. Failure to do so may result in fitting breakage or detachment of the tubing. Refer to the recommended piping conditions. 5. Do not apply unnecessary forces such as twisting, pulling, moment loads, vibration and impact, etc. on fittings or tubing. This will cause damage to fittings and will crush, burst or release tubing. 6. Tubing, with the exception of coiled tubing, requires stationary installation. Do not use standard tubing (non-coiled) in applications where tubing is required to travel. Tubing that travels may sustain abrasion, extension, or severance due to tensile force, or may result in removal of tubing from fitting. Use caution prior to use for proper application. 7. To install the fi tting, screw the fitting into the hexagonal face of the body, and tighten with an appropriate wrench. Affix the wrench at the base of the thread. If the size of hexagonal face and wrench do not match, or tightening takes place near the tube side, it may cause collapse or deformation of the hexagonal face, or damage to the equipment. After installing, confirm that there is no damage to the fitting, etc. Fittings & Tubing Precautions 1 Be sure to read this before handling. Here, η : Deformation ratio (%) d : Tubing diameter (mm) L : Measured length (mm) D : Mandrel diameter (mm) (Twice against the minimum bending radius) Test temperature: 20 ±5°C Relative humidity: 65 ±5% Tube deformation ratio at the minimum bending radius Design/Selection Mounting/Piping Warning Warning 1. Check the specifications. The products in this catalog are designed to be use d in compressed air systems (including vacuum) only. If the products are used in an environment where pressure or temperature is out of the specified range, damage and/or malfunction may result. Do not use under such conditions. (Refer to the specifications.) Please consult with SMC when using a fluid other than compressed air (including vacuum). We do not guarantee against any damage if the product is used outside of the specification range. 2. Do not dis assemble the product or make any modifications, including additional machining. It may cause human injury and/or an accident. 3. Check if PTFE can be used in application. PTFE powder (Polytetrafluoroethylene resin) is included in the sealant. Confirm that the use of it will not cause any adver se affect on the system. Caution 1. Keep the connection part of fittings and tubing from rotating or oscillating movement. Use Rotary One-touch Fittings (Series KS or KX) in these cases. The fittings may be damaged if they are used in the above manner. 2. The tubing bending radius in the vicinity of the fitting should be at least the minimum bending radius of the tubing. If the bending radius is less than the min. value, fittings may damage, or tubing may crack or be crushed. The minimum bending radius, with the exception of TS soft nylon tubing, TU polyurethane tubing, TUH hard polyurethane tubing, TUS soft polyurethane tubing, TRBU FR double layer polyurethane tubing, TH FEP tubing, TL PFA tubing, TD modified PTFE tubing, is measured as following in accordance with JIS B 8381-1995. Tubing deformation ratio at the minimum bending radius is obtained through the following formula, ba sed on tubing diameter and mandrel diameter by wrapping the same radius mandrel tube. 3. Do not use fluids other than listed on the specifications. Applicable fluids are air and water. Please consult with SMC if using other fluids. 4. When it is used with water, the fittings or tubing may be damaged depending on the surge pressure. 1. Operation manual Install the products and operate them only after reading the operation manual carefully and understanding its contents. Also, keep the manual where it can be referred to as necessary. 2. Ensure sufficient space for maintenance activities. When installing the products, allow access for maintenance. 3. Adhere to the thread tightening method. When installing the products, refer to “Connection Thread Tightening Method”. 4. There may be cases of the tubing detaching from the fitting and thrashing around uncontrollably due to tubing degradation or fitting breakage. To prevent the situation from becoming uncontrollable, fit the tubing with a protective cover or fix it in place. Caution η = L − D 2d1 − x 100

Air Supply Operating Environment 1. Type of fluids Please consult with SMC when using the product in applications other than compressed air. Regarding products for general fluids, please contac t SMC concerning applicable fluids. 2. When there is a large amount of drainage. Compressed air containing a large amount of drainage can cause malfunction of pneumatic equipment. An air dryer or water droplet separator should be installed upstream from filters. 3. Drain flushing If condensation in the drain bowl is not emptied on a regul ar basis, the bowl will overflow and allow the condensation to enter the compressed air lines. It causes malfunction of pneumatic equipment. If the drain bowl is difficult to check and remove, installation of a drain bowl with an auto drain option is recommended. For details on the above compressed air quality, refer to SMC’s Best Pneumatics catalog. 4. Use clean air. Do not use compressed air that contains chemicals, synthetic oils including organic solvents, salt or corrosive gases, etc., as it can cause damage or malfunction. 5. Do not use the ordinary fittings and tubing in locations where static electricity would be problematic. It may result in the system failure and trouble. In such places, use of antistatic fittings (Series KA) and antistatic tubing (Series TA) are recommended. 6. Do not use the ordinary fittings an d tubing in locations where spatter is generated. Spattering may result in a fire hazard. In such a place, use of flame resistant fittings (Series KR/KRM) and flame resistant tubing (Series TRS/TRB) are recommended. 7. Do not use in an environment where the product is directly exposed to cutting oil, lubricant, coolant oil, etc. Please contact SMC if using for an environment exposed to cutting oil, lubricant or coolant oil, etc. 8. Take note that if nylon tubing and soft nylon tubing are used in a clean room. The antioxidant on the surface of the soft nylon tubing may come off, thereby lowering the cleanness level. 9. Do not use in environments where foreign matter may stick to the product or get mixed in the product’s interior. This may cause leakage or disconnection of the tubing. 1. Install an air filter. Install an air filter at the upstream side of valve. Select an air filter with a filtration degree of 5 μm or finer. 2. Install an aft ercooler, air dryer or water droplet separator, etc. Compressed air that contains a large amount of drainage can cause malfunction of pneumatic equipment. Therefore, take appropriate measures to ensure air quality, such as by providing an aftercooler, air dryer, or water droplet separator. 3. Ensure that the fluid and ambient temperature are within the specified range. If the fluid temperature is 5°C or less, the moisture in the circuit could freeze, causing damage to the seals and leading to equipment malfunction. Therefore, take appropriate measures to prevent freezing. For details on the above compressed air quality, refer to SMC’s Best Pneumatics catalog. Operating Environment 1. Do not use in an atmosphere having corrosive gases, chemicals, sea water, water, water steam, or where there is direct contact with any of these. Refer to each construction drawing on the fittings and tubing material. 2. Do not expose the product to direct sunlight for an extended period of time. 3. Do not use in a place subject to heavy vibration and/or shock. 4. Do not mount the product in lo cations where it is exposed to radiant heat. Maintenance 1. Perform maintenan ce inspection according to the procedures indicated in the operation manual. If handled improperly, malfunction and damage of machinery or equipment may occur. 2. Maintenance work If handled improperly, compressed air can be dangerous. Assembly, handling, repair and element replacement of pneumatic systems should be performed by a knowledgeable and experienced person. 3. Drain flushing Remove drainage from air filters regularly. 4. Removal of equipment, and supply/exhaust of compressed air When components are removed, first confirm that measures are in place to prevent workpieces from dropping, run-away equipment, etc. Then, cut off the supply pressure and electric power, and exhaust all compressed air from the system using the residual pressure release function. When machinery is restarted, proceed with caution after confirming that appropriate measures are in place to prevent cylinders from sudden movement. Fittings & Tubing Precautions 2 Be sure to read this before handling. Warning Warning Warning Warning Caution

1. Installation and removal of tubing for One-touch fittings 1) Installation of tubing (1) Cut the tubing perpendicularly, being careful not to damage the outside surface. Use an SMC tube cutter “TK-1”, “TK-2” or “TK- 3”. Do not cut the tubing with pliers, nippers, scissors, etc., oth- erwise, the tubing will be deformed and trouble may result. (2) The outside diameter of the polyurethane tubing swells when internal pressure is applied to it. Therefore, it may be possible that the tubing cannot be re-inserted into the One- touch fitting. Check the tubing outside diameter, and when the accuracy of the outside diameter is +0.07 mm or larger for ø2, +0.15 mm or larger for other sizes, insert into the One- touch fitting again, without cutting the tubing to use it. When the tubing is re-inserted into the One-touch fitting, confirm that the tubing goes through the release button smoothly. (3) Grasp the tubing, slowly push it into the One-touch fitting until it comes to a stop. (4) Pull the tubing back gently to make sure it has a positive seal. Insufficient installation may cause air to leak or the tubing to release. 2) Removal of tubing (1) Push the rel ease button flange evenly and sufficiently to release the tube. (2) Pull out the tubing while keeping the release button depressed. If the release button is not held down sufficiently, the tubing cannot be withdrawn. (3) To reuse the tubing, remove the previously lodged portion of the tubing. If the lodged portion is left on without being removed, it may result in air leakage and removal of the tubing difficult. 2. Connecting products with metal rods Products with metal rods (Series KC, old Series KQ, Series KN, and Series KM, etc.) cannot be connected to Series KQ2 One-touch fittings. If connected, the metal rod cannot be retained by the chuck of the One-touch fitting and products with metal rods may project during pressurization, causing serious personal injury or accident. Even when products with metal rods can be connected to other One-touch fittings, do not use any tube, resin plug, or reducer after connection. This may cause releasing. For details about One-touch fittings that can connect products with metal rods, contact SMC. Caution 1. Be certain to wear safety glasses at all times during periodical inspections. 2. Replace fittings or tubing having the following problems. 1) Cracks, gouges, wearing, corrosion 2) Air leakage 3) Twists or crushing of tubing 4) Hardening, deterioration, softening of tubing 3. When replacing tubes or fittings, do not try to mend or repair and then reuse them. Connection Thread Tightening Method 1. Connection thread: M3 First, tighten by hand, then use a wrench appropriate for the hexagon flats of the body to tighten an additional 1/4 turn. A reference value for the tightening torque is 0.4 to 0.5 N·m. 2. Connection thread: M5 and 10-32UNF First, tighten by hand, then use a wrench appropriate for the hexagon flats of the body to tighten an additional 1/6 to 1/4 turn. A reference value for the tightening torque is 1 to 1.5 N·m. 3. M6 First, tighten by hand, then use a wrench appropriate for the hexagon flats of the body to tighten an additional 1/6 to 1/4 turn. Note) Excessive tightening may damage the thread portion or deform the gasket and cause air leakage. Insufficient tightening may loosen the threads, or cause air leakage. 4. Fittings with sealant: R, NPT 1. First, tighten the fitting by hand, then use a wrench appropriate for the hexagon flats of the body to tighten it a further two or three turns. For a tightening torque guide, see the table below. 2. If the fitting is tightened with excessive torque, a large amount of sealant will seep out. Remove the excess sealant. 3. Insufficient tightening may cause seal failure, or loosen the threads. 4. Reuse 1) Normally, fi ttings with a sealant can be reused 2 to 3 times. 2) To prevent air leakage through the sealant, remove any loose sealant stuck to the fitting by blowing air ov er the threaded portion. 3) If the seala nt no longer provides effective sealing, wrap sealing tape over the sealant before reusing. Do not use the sealant in any form other than a tape type. 4) Once the fitting has been tightened, backing i t out to its original position often causes the sealant to become defective. Air leakage will occur. One-touch Fittings Mounting/Piping Caution 3. When mounting tubes, resin plugs, reducers etc., do not press the release button. Also, do not press the release button before mounting. This may result in detachment. In particular, when piping products, such as plug-in elbows or reducers, etc. the release button may be pressed easily due to product handling during piping work.

Connection Thread Tightening Method 5. Face seal fittings: R, NPT, G 1. Tighten fittings with sealant using the proper tightening torques in the table below. 2. Insufficient tightening may cause seal failure, or loosen the threads. 3. Reuse 1) Normally, fittings with a sealant can be reused 6 to 10 times. 2) The seal ring cannot be replaced. Connection thread size (R, NPT, G) Proper tightening torque (N·m) 1/16, 1/8 3 to 5 1/4 8 to 12 3/8 15 to 20 1/2 20 to 25 øD 45° Caution 1. Chamfer dimension for female thread of the connection thread M3, M5, 10-32UNF Confirming to ISO 16030 (air pressure fluid dynamics – connection – ports and stud ends), the chamfer dimensions shown below are recommended. By chamfering as shown in the following table, machining of threads is easier and effective for burr prevention. Chamfer Dimension for Female Thread Connection thread size Chamfer dimension øD (Recommended value) (mm) M3 3.1 to 3.4 M5 5.1 to 5.4 10-32UNF 5.0 to 5.3 Connection Female Thread: Rc, NPT, NPTF Connection Female Thread: G 2) The gasket can be reused 6 to 10 times. It can be replaced easily when it has sustained damage. A broken gasket can be removed by holding it and then turning it in the same direction as loosening the thread. If gasket is difficult to remove, cut it with nippers, etc. In such a case, use caution not to scratch the seat face because the seat face of 45° gasket of fitting is the sealing face. 6. Uni thread fittings 1) First, tighten the threaded portion by hand, then use a proper wrench, which could be suitable for the width across flats of the hexagon body, to tighten it further at a wrench tightening angle shown below. As a reference value for the tightening torque, refer to the table below. Uni thread size Wrench tightening angle after hand-tightening (deg) Tightening torque (N·m) 1/8 30 to 45 3 to 4 1/4 15 to 30 4 to 5 3/8 15 to 30 8 to 9 1/2 15 to 30 14 to 15 Uni thread size Wrench tightening angle after hand-tightening (deg) Tightening torque (N·m) 1/8 30 to 60 3 to 5 1/4 30 to 60 8 to 12 3/8 15 to 45 14 to 16 1/2 15 to 30 20 to 22 45° Counterbore diameter øD3 Seal bearing surface diameter øD2 Rz 25 (Sealing face) Chamfer dimension øD1 Female thread inclination angle: 1° or less 3.
