RHCG Reducing Hex Couling Stainless Steel 316L Tube Fitting
Plumbing Fitting High Quality Sanmin
Installation Instructions
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
Fig.B )
Reassembly Instruction
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
felt .
Tube Cutter
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 .
Warning
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
Copper Tubing
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
.
Inspection Tubing
Use : This is a “ No- Go ” Gauge and should be used as follows :
Make up to fitting according to the following instructions : 1/4
inch ( 6mm ) , 3/8 inch , 1/2 inch ( 12mm ) – make up 1-1/4 turns
from finger tight . Check gap between nut and body , using the
appropriate sized gauge . If the gauge slides easily into the gap ,
tighten the nut further until gauge can not enter the gap
Tube Selection
Four variables must be considered when ordering tube for use with
fittings :
1. Material
2. Tube wall thickness
3. Tube surface finish
4. Tube hardness
Tubing should comply with standard ASTM A213 or ASTM A269 , be
seamless , and fully annealed .
The tube must be red of scratches and suitable for bending and
flaring .
