2. Specific Product Precautions (2)
(3) 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.
(4) 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.
(5) 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.
(6) To install the fitting, screw the fitting in using
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.
(7)
Use a tool with soft internal surface, such as
plastic to prevent damage to the fitting
surface.
After mounting, check that the fitting is not
damaged or deformed.
(8)
In case of top mounting, mount the fitting at
an angle so that water and detergent are not
accumulated in the fitting.
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.

Mount the fitting at an
angle to prevent water
and detergent from being
accumulated in the fitting.
