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 cutting
Two different methods can be used to cut tubes :
1 . Tube Cuter
2 . Hacksaw
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 .
Hacksaw Cutting
In order to cut the tube with a hacksaw and get square ends , the tube must be cut with guide blocks
This method of cutting necessitates deburring of the tube ends.
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 .
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
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 .
