Note 1) For soft nylon tubing, water cannot be used.
Note 2) Avoid using in a vacuum holding application such as a leak tester, since there is leakage.
Note 3) Check the operating pressure range and operating temperature range of the tubing.
Note 4) It is recommended that you use the inner sleeve in the following conditions (Except ø1/8"):
• When using in an environment where the fluid temperature changes drastically.
• When using at a high temperature.

Note 4) It is recommended that you use the inner sleeve in the following conditions:
• When using in an environment where the fluid temperature changes drastically.
• When using at a high temperature.

Specific Product Precautions
Be sure to read before handling. Refer to front matter 56 for Safety Instructions,
pages 13 to 16 for Fittings and Tubing Precautions.
Selection
Caution
Installation and Removal of Tubing
Caution
1. 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.
2. 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.
3. The particle generation of the KQB2 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 KQB2 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.
Mounting
Caution
1. 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.

KQ2
1. Installation of tubing
1) Grease is not used for the KQB2 series, therefore a greater KQB2
insertion force is required when the tube is installed. In KS
particular, polyurethane tubing may fold when inserted due KX
to its softness. Hold the end of the tubing, and insert it all
the way in slowly and securely. Refer to dimension “M” in KM
the dimension drawings for guidance on the insertion depth
of tubing.
KF
2. Removal of tubing
1) 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 M
One-touch fitting again due to an enlarged O.D. Dispose of H/DL
the tubing and replace it with a new one.

Proper Tightening Torque of Fittings
KK
Caution
1. Tighten fittings with sealant using the proper tightening torques in the table below. As a rule, they
should be tightened 2 to 3 turns with a tool after
first tightening by hand.
If tightened using a torque exceeding the proper torque level,
this may cause the fitting to break.
In particular, for the product with the stud, the stud may come
off.

Otherwise, air leakage or breaking can occur due to a pulling

3. The elbow union, branch tee, and long elbow union
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.
4. 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.
