MAKING STRAIGHT EXPANSIONS
Follow these steps to produce straight expansions using
the STEP expander dies. (See chart on page 12 for
typical end finishing illustrations.)
1. Retract the swager cylinder completely by lifting the
valve handle up.
2. Install the required STED for the appropriate tubing
size on the ST-1 adapter attached to the end of the
cylinder shaft.
3. Install the required HAC adapter collar around the
tubing and position within the swager clamp blocks.
The hinge should be positioned on the top side and
the smaller tapered edge of the collar should be
towards the cylinder shaft.
4. Leave at least three inches of tubing extended
beyond the inside edge of the adapter collar.
(See figure 1-A)
5. To secure the tubing firmly, snug the collar back into
the clamp blocks by gently pushing back on the collar
assembly.
6. Slowly, while depressing the valve handle down,
move the shaft forward until the expander die enters
the tubing. Be sure that the tool is centered with the
tubing. Continue moving the cylinder forward until
the expansion is formed. (See figure 2-A)
NOTE:
NEVER run the expander die into the tubing
more than 1/4” from the end of the die. NEVER
completely bury the die into the tubing.
7. After the tubing has been expanded, retract the die
by lifting up on the control handle.
8. Separate the collar from the tubing. Remove tooling
and return to the storage area.
USING THE STED EXPANDER DIES OR
THE B-2I2 TO MAKE MALE BALL EXPANSIONS
IMPORTANT NOTE:
When making male ball expansions it is
necessary to first install the pipe flange or clamp
around the tube prior to finishing the ends.
To make a male ball expansion using the STED
expander dies or B-212, proceed as follows. (See chart
on page 12 for typical end finishing illustrations.)
NOTE:
The “B” symbol stamped on the STED expander
dies identifies the tool required for making male ball
expansions. The “E” symbol identifies the tool required
for making straight expansions.
Some STED expander dies do not show a “E” or “B”
symbol. These are used for making straight
expansions only. The B-212 tool is used for making
male ball expansions on 2-1/2” tubing only.
1. Retract the swager cylinder completely by lifting the
valve handle up.
2. Install the required STED for the appropriate tubing
size or B-212 on the ST-1 adapter attached to the
end of the cylinder shaft.
3. Install the required HAC adapter collar around the
tubing and position within the swager clamp blocks.
4. Leave at least three inches of tubing extended
beyond the inside edge of the adapter collar.
5. Snug the collar back into the clamp blocks by gently
pushing back on the collar assembly.
6. Slowly, while depressing the valve handle down,
move the shaft forward until the tool enters the
tubing. Be sure that the tool is centered with the
tubing.
7. Slowly, bring the tool forward until it meets the marking
ring etched around the circumference of the tool. Do
not go beyond the grooved marking ring.
8. After the tubing has been expanded, retract the die
by lifting up on the control handle.
9. DO NOT remove tubing from the collar.
10. Install the DOMlNG DIE on the ST-1 adapter attached
to the end of the cylinder shaft. (See figure 3-A)

CAUTION!
BE SAFE. DO NOT rush any procedure. ALWAYS
operate the swager unit SLOWLY and CAUTIOUSLY.
KEEP HANDS CLEAR from all pinch points.
ALWAYS wear protective safety goggles.
