6.3 Serto installation instructions
1. Preparation
Cut the tube to length and deburr it. The tube must be straight and free from
blemishes for approximately 1,5 d from the end. The union is lubricated. Thus
lubrication with lubricating oil, MoS2, Teflon etc. is recommended for the
assembly and reassembly of bigger sized unions (thread, compression ferrule).
2. Reinforcing the tube and pushing it in
Stiffener sleeves* are required to reinforce plastic tubes and thin walled tubes
Copper from d 10 mm with s < 1,0 mm
from d 12 mm with s < 1.5 mm
Stainless from d 6 mm with s < 0.5 mm
steel from d 10 mm with s < 1.5 mm
Plastic all
Align tube and union. Insert the tube as far as the stop. Details see chapter tubes
in the appendix. www.serto.com
3. Compression, stress relieving
3.1 Screw on the union nut by hand until finger tight.
At the same time, push the tube against the fitting.
3.2 Tighten down the union nut 1% rotation using an open ended spanner.
(Making a mark will assist in correct rotation.)
3.3 Slightly release the nut once again to take the radial stress off the tube.
3.4 Checking of fit. A distinct bead or deformation must be visible on the inside of
the tube.
3.5 Screw on the union nut until finger tight again and tighten down the union nut
with + rotation for the final fit. (Hold adaptor from turning with a second
wrench.)
4. Repeated fitting of the union
When refitting the same tube union, screw the union nut back on by hand until
finger tight and tighten down the union nut with an open ended s rotation
for the final fit.
In case of repeated assembly, parts must be lubricated.
Tubes*
Tubes with a clean smooth external surface and with an outside diameter within
the tolerance ± 0.1 mm should be used.
Turnable compression ferrule
It is of no detriment to the efficiency of the connection if, after assembly, the
ferrule can be turned on the tube, or the tube in the union nut.
