Datasheet

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 pipe tape
When screwing together pipes and
fittings, etc., be certain that chips
from the pipe threads and sealing
material do not get inside the pipe.
Also, when the pipe 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 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 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,
extention, 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 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.

Warning Warning
1. Check the specifications.
The products in this catalogue are designed to be used 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 disassemble 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
seal material. 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. 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, based 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. Tighten threads with the proper tightening torque.
When installing the products, follow the listed torque
specifications.
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.
