2. Specific Product Precautions (1)
Warning
(1)Check the specifications.
The products in this catalog 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 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. 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 in 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)The 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 or the tubing may
result in being fallen out.
(6)If using a fluororesin tubing in an
environment where the fluid temperature
changes drastically, it is recommended to
use an inner sleeve. Otherwise, air
leakage may occur or the tube may
release from fitting due to deformation of
the tubing.
(7)The particle generation of the KQG2 series
depends on the operating conditions and
operating environment. If you are
concerned about the effects on machinery
and equipment, check the particle
generation with your machine before use.
The components of the KQG2 series may
slide due to changes in the internal pressure,
which may generate particles. When using
male elbow, male branch tee, and extended
male elbow fittings, particles may be
generated by rotation for positioning after
connecting.
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.

2. Specific Product Precautions (2)
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)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 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 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 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.
(8)When performing the piping work, turn the
tightening tool in the horizontal direction to
the hex. across flats of the stud so that any
moment is not applied to the body.
If the tool is in contact with the body, this may
cause the stud to come off.
(9)The union elbow, union tee, union "Y",
different diameter tee and different diameter
union "Y" should be fixed through the
mounting hole.
Otherwise, air leakage or breaking can occur
due to a pulling force or moment load created
by the product's weight.
(10)The male elbow, male branch tee, and
extended male elbow can be turned for
positioning after connecting, but they
cannot be used while turning them.
Doing so may cause worn out metallic particles
to enter the fluid or the fitting to break.
(11)If the connection tube oscillates or turns,
do not use this product.
Doing so may cause the fitting to break. In
particular, for the product with the stud, this may
cause the stud to come off.
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 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 regular 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.

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 and 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 environment 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.
(10)Avoid installing and using fittings inside a
food zone.

2．Specific Product Precautions (4)
Caution
(1)Installation and removal of tubing for
One-touch fittings
a）Installation of tubing
1. Cut the tubing perpendicularly, being careful
not to damage the outside surface. Use an
SMC tube cutter TK-1, 2, 3, 5 or 6. Do not cut
the tubing with pliers, nippers, scissors, etc.,
otherwise, 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 +0.15mm or larger, 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. Grease is not used for the KQG2 series,
therefore a greater insertion force is required
when the tube is installed. In particular,
polyurethane tubing may fold when inserted
due to its softness. Hold the end of the tubing,
and insert it all the way in slowly and securely.
Refer to dimension "M" in the dimension
drawings for guidance on the insertion depth
of tube.
4. Grasp the tubing, slowly push it straight (0 to
5o) into the One-touch fitting until it comes to a
stop.
5. 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.
As a guide for checking the tubing is not
pulled out, refer to the following table.
b）Removal of tubing
1. Push the release button flange evenly and
sufficiently to release the tube. Do not push in
the tubing before pressing the release button.
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.
4. For tubing used at a high temperature or for
an extended period of time, there is a
possibility that it will not fit into a One-touch
fitting again due to an enlarged O.D. Dispose
of the tubing and replace it with a new one.
(2) Connecting products with metal rods
Products with metal rods (Series KC, Series
KQ2, old Series KQ, Series KN, and Series KM,
etc.) cannot be connected to series
KQG2/Stainless steel 316 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 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.

2．Specific Product Precautions (5)
Caution
(1) 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.
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.
(2) Connection thread: R and NPT
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, this may
cause the fitting to break. In particular, for the
product with the stud, the stud may come off.

NPT、R1/8 3 to 5
NPT、R1/4 8 to 12
NPT、R3/8 15 to 20
NPT、R1/2 20 to 25
(3) If the fitting is tightened with excessive
torque, a large amount of sealant will seep
out. Remove the excess sealant.
(4)Insufficient tightening may cause seal failure,
or loosen the threads.
(5) Reuse
a) Normally, fittings with a sealant can be reused
2 to 3 times.
b) To prevent air leakage through the sealant,
remove any loose sealant stuck to the fitting
by blowing air over the threaded portion.
c) 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.
(6) 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
(1) Chamfer dimension for female thread of the
connection thread
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

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 a 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 is no stainless steel with an absolute
corrosion resistance; therefore, many types of stainless steel have been
developed for improved corrosion resistance performance.
