9. Lift the valve handle up until the arbor extends and
the segment set is released.
10. Check the finished expansion end by placing it over
the end of tubing of the corresponding size. The
expansion should allow the tubing to fit snugly.
11. The expansion can be made to fit looser by turning
the buttress canister counter-clockwise or tighter by
turning the buttress canister clockwise.
USING THE BALLJOlNT SEGMENT SETS - Ball-joint
segment sets are used to make ball-joint expansions
on shorter tubing ends. They are available in three sizes;
2”, 2-1/4” and 2-1/2”. These are not included in standard
tooling packages. (See chart on page 12 for typical end
finishing illustrations.)
Ball-type expansions can be made quick and easily using
ball segment sets on the internal expander as explained
below.
1. Slide the proper size ball-joint segment set over the
arbor. (See figure 1-A)
2. Place the tubing over the ball segment set until the
tubing end is flush with the shoulder.
3. Adjust the buttress canister until the grooved line on
the canister is lined up with the grooved line on the
pointer.
4. Depress the valve handle to form the ball on the end
of the tubing. Be careful not to distort the end of the
tubing. (See figure 2-A)
5. To make a female ball expansion, place the tubing
over the arbor and segment set until the tubing is
positioned midway at the grooved area. Depress the
valve handle to flare the end of the tubing to match
with the mating male ball joint. (See figure 3-A)
USING THE FLARE SEGMENT SETS - These segment
sets are used to make 45 degree flares on tubing ends.
Three different sets are available that work on tubing
sizes 1-1/2” - 2-1/2”. These are not included in standard
tooling packages. (See chart on page 12 for typical end
finishing illustrations.)
To produce a flare, proceed as follows.
1. Slide the proper size flare segment set over the arbor.
(See figure 1-B)

HELPFUL TIP...
Cut off sections of tubing in all sizes approximately 3” in
length and weld them to a bracket similar to the one
shown below. Attach to your bender and use it to check
your expansions.
