RU Pneumatic Tube Fittings Reducing Union Plumbing Fitting Pneumatic Air Fitting High Quality Sanmin

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 .

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 .
