Tubing Connection and Removal
Installing of tube
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.
0.5mm between the tubing end and the
barb end.
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.
Sleeve
Gap (approx. 0.5mm)
There should not be any gap.
Note) When installing the tubing, the sleeve
must be attached. Operation without
attaching the sleeve may cause
tubing disconnection.
Removing of tube
Withdraw the sleeve straight along the
tubing. Use a tool such as long-nose pliers
if it is difficult to pull out by hand.
1. Withdraw the tubing straight.
2. When reusing the tubing, cut off the
previously installed portion of the tubing to
avoid possible leakage and/or
disconnection of the tubing.
