4. SWAGING TOOL

5. PINCHING TOOLS

6. PRESSURE GAUGE

7. COMPOUND GAUGE

8. THEMOMETER

FLARING TOOLIt is used for making of different sizes of flares copper tubes

TUBE CUTTER

Small diameter annealed (soft) copper tubes are used in most

refrigeration work. Tube cutter are used to cut these tubes. It consist of ‘v’ block against which the tube rests and an adjustable round blade of carbon steel which cut the tube. Some tube cutters are equipped with a reamer for removing the burr at the cutting end of the tube.

Its size depends upon the maximum diameter Of the tube which it can cut

Pipe bending tool

There are external coil bending tool s where the external spring is designed to be used near the end of tubes

A lever type tube bender is used to form bends neatly and accurately without buckling the tubing. These tools will form bends up to 180o in the continuous operation .the forming wheel is calibrated to show the degree of bend attained.
