2. Place the Tubing over the Arbor and Segment Set, but
DO NOT place the end of the Tubing past the last
step on the Segment Set. (See figure 1-A)
3. Press the Valve Handle and rotate the Tubing
clockwise until the desired Flare is produced.
NOTE:
Smaller size Tubing should be gradually
worked up onto the Flare Segment Set until
the desired Flare has been produced.
USING THE MANIFOLD FLANGE SEGMENT SETS
These Segment Sets are used to make Donut-Type
Manifold Flanges on Tubing ends. They are available in
five sizes; 1-1/4”, 1-1/l2”, 2”, 2- 1/4”, and 2-1/l2”. All
Manifold Segment Sets are used in conjunction with Limit
Rings. These are not included in standard tooling
packages.
(See chart on page 12 for typical end finishing illustrations.)
To produce a Manifold Flange proceed as follows:
1. Place the proper size Segment Set over the Arbor.
(See figure 1-B)
2. Place the proper size limit ring over the end of the
Tubing.
3. Position the Tubing over the Arbor and Segment Set
until the Tubing meets the shoulder.
4. Push the limit ring forward until it also meets the
shoulder and is flush with the end of the Tubing.
(See figure 1-C)
5. Press the Valve Handle to form the flange. The
flange will be formed as the raised areas expand and
the Tubing end is contained by the limit ring.
USING THE SWAGING BOX
The Swaging Box is an expanding/flaring unit located to
the rear of the Bender, which utilizes Pipe Collars in
conjunction with bullet shaped Expander/Forming Dies to
perform a variety of Tube End finishing.
USING THE “STED” EXPANDER DIES - STED's are
referred to as “Solid Expander Dies”. Each Tool is marked
for the proper size Tubing. Some of these Dies perform
two different functions. The STED Expander Dies will
Swage/Expand the Tubing to exact inside diameters but
some can also be used for making Male Ball Expansions.
The Tooling applications are explained below.

CAUTION!
NEVER use a limit ring that is defective or cracked.
DO NOT maintain constant pressure on the limit ring by
continuing to hold the Valve Handle down once the
expansion has been made. ALWAYS wear protective
safety goggles when operating the Internal Expander.
CAUTION!
Read the following section carefully before attempting
to operate the Swaging unit. BE CAREFUL when using
the Swaging assembly due to the extreme pressure
created by the Hydraulic Cylinder. NEVER allow
untrained personnel to operate machinery.
KEEP HANDS CLEAR of all pinch points. ALWAYS
wear protective safety goggles.
