RA Type Reducing Adaptor 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

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
