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 BALL JOINT 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 quickly 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. Press 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. Press 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 includ-
ed 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.

HELPFUL TIP
Make an expansion gauge to quickly check your
expansions. Cut off sections of Tubing in all sizes
approximately 3” in length. Weld them to a bracket similar
to the one shown below and attach to your Bender.
