    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 .
    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 .
