Tubing Connection and Removal
Connection of tubing
1. Cut the tubing perpendicularly allowing
additional length.
2. Insert the tubing into the sleeve.

3. Insert the tubing slowly into the fittings.
Make sure to secure a gap of approx. 0.5
mm between the tubing end and the barb
end.
Gap (approx. 0.5 mm)

Attaching the sleeve
achieves a larage retaining
force.
Detaching it allows easy
removal of the tube.

How to Order
Note) When installing the tubing, the sleeve
must be attached. Operation without
attaching the sleeve may cause tubing
disconnection.
There should not be any gap.

4. Insert the sleeve slowly. Make sure not to
allow any gap between the sleeve end
side and the body end side. (Please refer
to the illustration below.)
If you feel any strong resistance and
cannot push the sleeve completely to the
end side, this may be caused due to
jamming. Remove and repeat again by
starting from step 1 making sure to
secure a gap in the step 3.

Removal of tubing
1. Withdraw the sleeve straight along the
tubing. Use a tool such as long-nose
pliers if it is difficult to pull out by hand.
2. Withdraw the tubing straight.
3. When reusing the tubing, cut off the
previously installed portion of the tubing
to avoid possible leakage and/or
disconnection of the tubing.

Tightening of M3/M5 Threads
Caution
1. Tighten by hand, and give it an additional turn
with a wrench.
Please check the number of tightening
revolutions using the table below.
If tightened excessively, thread portion may be
damaged and gasket may be deformed. This
will cause air leakage. On the contrary, if
tightened insufficiently, thread may loosen
causing air leakage.

Thread
Use of Tube with Hose Nipple
Caution
1. Cut the tube perpendicularly to the tube
axis to a little longer than required length.
(Use tube cutter “TK-1”, “TK-2” or “TK-3”.)
2. Pass the tube through the cap nut.
3. Push the tube until it comes to the end of
the barb portion, or it may cause air
leakage or hose releasing.
4. Tighten the cap nut firmly by hand on the
fitting.
