HYDRAULIC FLARING AND SWAGING INSTRUCTIONS
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)
FIGURE 2
Insert the tube between the die blocks
as shown.
When swaging,
position tube even
with the end of the
die blocks.
When flaring,
position tube even
with line "guide"
on die block bore.
FIGURE 3
Insert and tighten the dies and tubing
into the yoke. It is important to securely
fasten the die blocks.
Securely fasten die blocks by turning the
"T" handle clockwise.

Lubricate "T" handle threads and yoke/hydraulic
cylinder threads with EP grease as needed.
Clean internal die block threads with brush
periodically to remove any debris ensuring a tight
grip on tubing when flaring or swaging.
FIGURE 4
Hold the yoke and rotate the hydraulic
cylinder clockwise to advance swage
adapter until front of adapter is even with
die blocks. Flare adapter should be
engaged in tube.
When you rotate the
cylinder, the adapter
will travel towards the die.
FIGURE 5
With relief valve closed securely, begin
pumping the handle. Continue pumping
until the edge of the adapter meets
the die.
Securely fasten die blocks by turning the
"T" handle clockwise.
OPEN CLOSE
FIGURE 6
Hold the yoke and rotate the hydraulic
cylinder counterclockwise to remove the
adapter from the die blocks.
DO NOT loosen the "T" handle
until adapter is outside of the die blocks.
Some resistance while turning is normal.

*OIL CHECK*
Please note that oil check should only be done if there are traces of oil found suggesting
some type of leak.
Check hydraulic oil level. Hydraulic oil can be checked by unscrewing back part of hydraulic
cylinder. Rotate endcap (round textured section under pump handle) counterclockwise until sepa-
rated from main body. Hold tool vertical with rubber reservoir at top. Remove small plug from end
of reservoir. With piston in full retract position, hydraulic oil should fill reservoir. Add hydraulic oil
as needed. Use hydraulic oil with a viscosity of about 46. Replace plug and endcap.
