11 Bender Operation Manual
SEGMENT EXPANDERS - Segment expanders or “seg-
ment sets” come in a variety of sizes and shapes, each
performing it's own distinct function. Segment sets are
used for short pieces of tubing or when the tubing end is
minimized due to an existing bend. They can also be used
to expand tubing that is deformed in such a manner that
will not permit use of the swager expander. Segment sets
are used in conjunction with an arbor or mandrel. All seg-
ment sets are identified by grooved rings located at the
bottom as described on the following chart. There are
four different types of segment sets available; STANDARD
SEGMENT SETS, MANIFOLD FLANGE SEGMENT
SETS, BALL-JOINT SEGMENT SETS, and FLARE
SEGMENT SETS.
STANDARD SEGMENT SETS - These segment sets are
used to make straight expansions on tubing ends and are
found in all standard tooling packages.
MANIFOLD FLANGE SEGMENT SETS - These segment
sets are used to make donut-type manifold flanges on tub-
ing ends. They are available in five sizes; 1-1/4”, 1-1/2”,
2”, 2-1/4”, and 2-1/2”. All manifold segment sets are used
in conjunction with limit rings. Not included in standard
tooling packages.
BALL-JOlNT SEGMENT SETS - These segment sets are
used to make ball-joint expansions on tubing ends. They
are available in three sizes; 2”, 2-1/4” and 2-1/2”. Not
included in standard tooling packages.
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”.
Not included in standard tooling packages.
NOTE:
Keep segment sets and arbor well greased.
The ARBOR which is pulled through the center of the seg-
ment sets is available in two sizes. The HSA-114 is an
arbor used exclusively for 1-1/4” and 1-3/8” tubing while
the HSA-112 is used for tubing sizes 1-1/2” through 3”.

WARNING!
1. Always remove excess tooling from swager area
before using internal expander.
2. To avoid breaking tooling ALWAYS use proper
segment sets with appropriate tubing size.
3. NEVER stand in front of arbor when operating
internal expander.
