CAUTION!
The connection between nylon tubing and fir-tree
must under no circumstances be secured by
hose clips or by clamping sleeves.
Nylon tube pliers
4 Assembly instructions
4.1 Cutting nylon tubing to
length
The nylon tube must be cut
off square. A saw may not be
used for this purpose as the
possible formation of burrs will
jeopardise the sealing capabi-
lity of the connection. For cut-
ting nylon tubing to the cor-
rect length, we recommend
the use of the VOSS cutting
pliers shown on the right,
which ensure that the tubing
is cut squarely and cleanly.
Subsequent treatment of the
cut surface such as deburring
is no longer necessary then.
4.2 Insertion of the fir-tree
in nylon tubing
The following has to be
observed when pressing the
fir-tree into the nylon tube:
- Insertion procedure must be
carried out at room tempera-
ture
- Nylon tube may not be
heated
- Fir-tree must be undamaged
as the connection to the
nylon tubing will otherwise
not be tight
- Fir-tree must be clean and
free of any grease

4.2.1 Insertion of the
fir-tree with the nylon
tube collet
Insert the nylon tube into the
opened pliers in such a way
that the end of the tube
extends approx. 2 mm for
brass plugs and approx.
6 mm for nylon plugs from
the side of the pliers without
serration. Fix the nylon tube
into place with the grip
mechanism. The clamping
force exerted may be varied
by means of the adjusting
screw.
Press the fir-tree as far as
possible into the end of the
tube manually. Then drive the
plug into the polyamide tube
with the aid of a plastic ham-
mer until the fir-tree is fully
covered by the tube. The plug
has to be protected by a plas-
tic cap.
