HYDRAULIC FLARING AND SWAGING INSTRUCTIONS
Warning!
Wear Safety Glasses
Note: Copper tube to be flared or swaged should be cut clean and square. Use a tool made to cut copper
tubing such as a commercial grade tube cutter. *The end must be deburred on the inside and outside of
the tube.
1. Open the relief valve by turning
counterclockwise. Hold the yoke
and rotate the hydraulic cylinder
until last thread on cylinder is
even with yoke
base. (Ref. Fig. 1)
2. Position the
correct size die
set and tube in
the yoke assembly.
Tube end should be even with face of die blocks for swage and even with mark on die blocks
for flare. (Ref. Fig. 2)
3. Tighten "T" Handle (rotate clockwise) to lock die blocks and tube in yoke. When swaging,insert correct
size swage adapter into adapter seat on end of piston (slotted end of adapter fits into grooved end of
piston). When flaring, insert cone shaped adapter. (Ref. Fig. 3)
4. Close relief valve by rotating clockwise. When swaging, hold yoke and rotate hydraulic cylinder clockwise
advancing adapter as close to die blocks as possible, without inserting into tube. When flaring, rotate the
hydraulic cylinder clockwise advancing the adapter to engage the tube. (Ref. Fig. 4)
5. Slowly pump handle. As piston advances, make sure adapter enters tube smoothly. Continue pumping
until resistance from pump handle is felt and large flange on swage adapter reaches face of die blocks or
cone adapter has engaged die blocks. Stop pumping, swage or flare is complete. (Ref. Fig. 5)
6. Open relief valve, DO NOT loosen "T" Handle. Hold the yoke and rotate hydraulic cylinder counter
clockwise until adapter is fully disengaged from die blocks. Loosen "T" Handle (rotate counter clockwise)
and remove die block and tube from yoke. (Ref. Fig. 6)
