HCG Hex Coupling Stainless Steel 316L Tube Fitting Plumbing Fitting High Quality Sanmin
Tube Fittings Description
The tube fitting is a mechanism used both to seal and to grip
tubing . The mechanical advantage and geometry of this kind of
fitting produces a leak – tight assembly .
To assemble , simply insert the tube into the complete assembly
until the tube bottoms – out against the shoulder of the fitting
body . The two ferrules are driven forward between the nut and
fitting body using the mechanical force created by rotating the nut
clockwise . The Back ferrule is driven against the tapered rear of
the front ferrule is driven by force into the tapered mouth of the
body .
The rear ferrule is swaged radially inwards on the tube while
lifting the front ferrule out to form a full – faced seal on the
tapered surface of the body .
The 1-1/4 Turn of the nut from the hand tight position assures
consistent drive of the sealing members . This ensures an effective
seal against high pressure as well as ultra high vacuum conditions
.
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 ).
Tube Handling
Scratches on the tube might cause leaks . it is , therefore ,
important to handle the tube carefully to reduce the risk of leaks
.
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
.
High Safety
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
application
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 .
