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 .
