Face seal adopted for threading.
Original thread construction which allows for the use of piping taper female threads (Rc, NPT)
Allows for neat and
compact piping
without protruding
threads
<Application example>
Mounted to a blow gun
(VMG11W-02-01)
After hand-tightening After hand-tighteningAfter tool-tightening After tool-tightening
Re-piping is possible.
Sealant tape is necessary because sealant be-
comes separated with repeated installation.
Repeated re-piping of up to 6 to 10 times is possi-
ble due to use of elastic sealant on seating.
Prevention of sealant residue/protrusion
The current 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.

Prior to Use
Fittings with Sealant
Seal material (fluororesin) is coated on the thread part with the proper thickness and range, that reduces the piping work, such as coating the seal
on the thread.
Female Thread Conditions Applicable to Face Seal
1. Surface roughness of bearing surface: Rz 25 or less
2. Chamfer dimension: øD1, Seal bearing surface diameter: øD2 (Refer to the table below.)
3. Female thread inclination angle: 1 or less
4. Counterbore diameter when the female thread is counterbored.: øD3
· Models with width across flats: Body width across flats x 1.1 or more
· Models other than hexagon (Hexagon socket head male connector etc.): Body dimensions + 0.2 mm or more
The width across flats and the body dimensions differ depending on the model even when the same thread size is used.
Refer to the dimensions in the catalog.
5. If oil content or sealant is sticking to the female thread, this may cause damage of the product. Remove it before piping.
Table 1
Precautions
For products that do not satisfy the female thread conditions shown above and the piping with a piping pitch narrower than the product dimension,
use the current sealant type.
The rubber parts of the face seal cannot be replaced.
The rubber parts of the face seal may fall off by the air blow and they cannot be mounted again. Be careful not to perform the air blow.

direction
Sealant tape
Expose approx. 1
thread ridge.
1. Keep the connection part of fittings and tubing from
rotating or oscillating movement. Use Rotary
One-touch Fittings (KS or KX series) 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.
I f the bending radius is less than the minimum value, fittings may
damage, 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), and soft polyolefin tubing (TPS
series) is measured as following in accordance with JIS B 8381.
Tubing deformation ratio at the minimum bending radius is
obtained through the following formula, based on tubing diameter
and mandrel diameter by winding 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.
5. Depending on the storage or operating environment
and the period of storage or use, the surface of the
brass (C3604) may blacken. If the discoloration of
the brass is a problem, we recommend selecting
electroless nickel-plated brass instead.
Example) KQ2H06-01 NS
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 approx. 1 thread ridge
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
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 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.

1. Type of fluids
Please consu lt wit h S MC when us ing th e 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 drainage can
cause malfunction of pneumatic equipment. An air dryer or
water 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. This causes the malfunction of
pneumatic equipment.
If the drain bowl is difficult to check and remove, the installation
of a drain bowl with an auto drain option is recommended.
Refer to “SMC Air Preparation System” for further details on
compressed air quality.
4. Use clean air.

problematic.
It may result in the system failure and trouble. In such places,
use of antistatic fittings (KA series) and antistatic tubing (TA
series) 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 (KR/KRM series) and flame resistant
tubing (TRS/TRB/TRBU/TRTU series) 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.
Warning
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 m or finer.
2. Install an aftercooler, air dryer or water separator,
etc.
Compressed air containing a large amount of drainage can
cause the malfunction of pneumatic equipment. Therefore,
take appropriate measures to ensure air quality, such as by
providing an aftercooler, air dryer, or water 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

Maintenance
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, 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 +0.07 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.
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.

Precautions 3
Be sure to read this before handling products.
1. Perform maintenance inspections 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. 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.
Warning
(3) Grasp the tubing, slowly push it straight (0 to 5 ) 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.
As a guide for checking the tubing is not pulled out, refer to
the following table.
Tubing size Tensile force of tubing [N]

2) 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 d own
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 (KC series, previous KQ series, KN
series, and KM series, etc.) cannot be connected to KQ2
series 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.

2) The gasket can be reused up to 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.

Be sure to read this before handling products.
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 up to 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, wind
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.
