Product Description

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 .
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 .
