Fittings are supplied assembled and finger tight . Disassembly
before use can allow the entry of dirt or other particles
1 . Insert the tubing into the fitting
Check That the tube rests firmly on the fitting shoulder and that
the nut is finger tight , At this point it is recommended that a
scribe mark be drawn on the hex of the extending onto the fitting
body . This mark will serve as an indicator for the starting point
and proper pull – up .
2 Tighten the nut
1-1/4 Turns of the nut are required for 1/4” (6mm) and higher ( See
Fig . A )
3/4 Turn of the nut is required for 3/16” (4mm) and lower ( See
Connections may be disconnected and remade repeatedly , without
loss of leak tight seal .
1. Before disconnecting , Mark the position of the nut inrelation to
the fitting body .
2. To reassemble , use a wrench to tighten nut to original position
3. Tighten slightly with wrench until a slight rise in torque is
To attain a leak free connection , the tubing must be cut squarely
. A good quality tube cutter with the appropriate blade for the
tubing material is recommended .
Do not try to reduce the time of cutting by taking deep cuts with
each turn the cutter . This will work harden the tube .
The end of the tube must be deburred to avoid damage to the fitting
and to ensure that the rube reaches the bottom of the fitting .
Do not hold the tube in a vise in the place where it will be
inserted into the fitting ( the vise will leave a mark on the tube
that may cause leaks , and might cause ovality ).
Some Recautions to be taken
1.Tubes must not be dragged on the floor .
2.Tubes must not be dragged out of a tubing rack , especially in
case of large OD tubes
If using copper tubing from a roll , hold the end of the tube and
roll the roll outwards allowing the tubing to lie on a flat surface
In applications where severe conditions and high pressure exist ,
we recommend the following installation procedures :
1. Check that the nut is finger tight
2. Insert the tube ( Up to the shoulder )
3. Rotate the nut with a wrench until the tube does not rotate freely
4. Mark position of the nut .
5. Rotate the nut 1-1/4 turns .
This method ensures that even if the tube O.D. is at the minimum
tolerance , the ferrules will be in contact with the tube for the
full 1-1/4 rotation.
In order to assure maximum fitting reliability and performance ,
great care should be given when selecting the tubing for each
Four variables must be considered when ordering tube for use with
2. Tube wall thickness
