Specific Product Precautions (1)

Design/Selection

Warning

1. Check the specifications.
   The product in this catalog is designed to be used in compressed air systems (including vacuum) only. If the product is used in an environment where pressure or temperature is out of the specified range, damage and/or malfunction may result. (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 disassemble the product or make any modifications, including  additionalmachining.
   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 adverse affect on the system.

Caution

1. Keep the connection part of fittings and tubing from rotating or oscillating movement. The fittings may be damaged if they are used in the above manner. Especially for swivel elbow, repeated load applied from the connected tubing may cause detachment from the stud.

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 minimum value, fittings may be damaged, or tubing may crack or be crushed. The minimum bending radius of the FR soft nylon tubing (TRS series), FR double layer tubing (TRB series), antistatic soft nylon tubing (TAS series), polyolefin tubing (TPH series), soft polyolefin tubing (TPS series) is
   measured as following in accordance with JIS B8381. Tubing deformation ratio at the minimum bending radius is obtained through the following formula, based on tubing diameter and mandrel diameter by wrapping the same radius mandrel tube.
   Tube deformation ratio at the minimum bending radius 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 o C
   Relative humidity: 65 +/5%

3. Do not use fluids other than listed on the specifications.
   Applicable fluids are air, N2 ,water and steam.
   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.

5. Surge pressure must be under the maximum operating pressure. If the surge pressure exceeds the maximum operating pressure, it will result in damage to fittings and tubing.

6. When using the swivel elbow, particles may be generated by rotation for positioning after connecting. If you are concerned about the effects on machinery and equipment, check  the particle generation with your machine before use.

Mounting/ Piping

Warning

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

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. Winding of sealant tape
   When screwing together pipes and fittings, etc., be certain that chips from the pipe threads and sealant do not get inside the pipe. Also, when the sealant tape is used, leave approximately 1 thread ridge exposed at the end of the threads.
   2. Specific Product Precautions (2)
   Mounting/ Piping

3. Check the model, type and size before installation. Also, confirm that there are no scratches, gouges or cracks on the product.

4. When connecting 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 the 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  inside the flexible protection tube. 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 fitting, screw the fitting in  using the hexagonal face of the body, andtighten 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.

8. The swivel elbow rotation is only for positioning after mounting the product. It is not intended for repeated rotation or oscillation, which will cause wear, resulting in metal particles which may enter the operating fluid or cause fitting damage. 

Piping Method
Caution

1. Take a tube having no flaws on its periphery and cut it off at right angles. (Use SMC’s tube cutter TK-1, 2, 3, 5 or 6 for cutting. Do not  use pinchers, nippers or scissors, etc.) The tubing might be cut diagonally or flattened, making installation impossible or causing problems such as disconnection and leakage.

2. Insert the tube into the union nut with the union nut removed. Grab the tube and gently push it throughly into the fitting.

3. After insertion, tighten the union nut temporarily by hand.

4. Fix the body with a tool. Tighten the union nut to the end surface of the body using a suitable wrench.
   Hex. across flats may be deformed, if using an improper wrench for hex. across flats. If the body is not secured with a tool, this may cause breakage. (In particular, for the swivel  elbow, the stud may come off).

5. Fix the body with a tightening tool. Tighten the union nut to the end surface of the body using a suitable wrench. Hex. across flats may be deformed, if using an improper wrench for hex. across flats. Tighten the union nut with the proper tightening torque shown below.

Warning

1. Type of fluids
   Please consult with SMC when using the product in applications other than compressed air.
   Regarding products for general fluids, please contact SMC concerning applicable fluids.

2. When there is a large amount of drainage.
   Compressed air containing a large amount of condensate can cause the malfunction of pneumatic equipment. An air dryer or water droplet separator should be installed upstream from the filters.

3. Drain flushing
   If condensate in the drain bowl is not emptied on a regular basis, the bowl will overflow and this may cause the 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.

Caution

1. Install an air filter.
   Install an air filter at the upstream side of valve.
   Select an air filter with a filtration degree of 5μm or finer.

2. Install an after cooler, 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 o 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.

2. Specific Product Precautions

Maintenance

Warning

1. Perform maintenance inspections according to the procedures indicated in the operation manual.
   If handled improperly, malfunction and damage of machinery of equipment may occur.

2. Maintenance work
   If handled improperly, compressed air can be dangerous. The 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 the equipment is restarted, proceed with caution after confirming that appropriate measures are in place to prevent cylinders from sudden movement.

Caution

1. Be certain to wear safety glasses at all times during periodical inspections.

2. During regular maintenance, check for the following and replace any components as necessary.
   a) Scratches, gouges, abrasion, corrosion
   b) Leakage
   c) Flattening or distortion of tubing
   d) Hardening, deterioration or softness of tubing
   e) Loosening of the union nut

3. Do not repair the fittings or patch the tubing for reuse.

4. After operation at a high temperature, leakage may occur due to time dependent change of the tube material. If leakage occurs, remove the tube, cut off the connecting part of the tube, and connect to the piping again.
   Check if the tube dimension accuracy is within the recommended tolerance. If it is difficult to take the tube out of the body, bend the tube to the side to remove.

Connection Thread Tightening Method
Caution
(1) 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.
   If the fitting is tightened with excessive torque, the fitting may break. In particular, for the swivel elbow, the stud may come off.Connection thread size| Tightening torque [N・m]
   ---|---
   NPT, R1/8| 3 to 5
   NPT, R1/4| 8 to 12
   NPT, R3/8| 15 to 20
   NPT, R1/2| 20 to 25

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, fittings 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 over the threaded portion.
   3. If the sealant 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 it out to its original position often causes the sealant to become defective. Air leakage will occur.

Caution
Precautions for use with non-SMC

1. When using the KFG2 series with tubing other than those from SMC, the products are not subject to warranty.

Construction

Stainless steel
Metal exists in nature as ore (like oxide or sulfide). This means that oxide or sulfide is more stable than pure metal. Accordingly, metallic material chemically oxidizes (metallic constituent becomes ion and melts out). It corrodes in the natural environment.
Even though corrosion of metal easily occurs in an environment where oxidizing tendency is stronger, some kinds of metal have a characteristic for which corrosion never happens if the level of oxidizing goes higher than a specific point. In such case, it is called “metal in passive state”.
Stainless steel has corrosion resistance because of a thin coat of passive state on its surface. However, there does not exist stainless steel with absolute corrosion resistance; therefore, many types of stainless steel have been developed for improved corrosion resistance performance.
