Parflange ECO 25
Hydraulic Flanging and Flaring Tool
Features and Advantages
Easy to Operate
The ECO 25 is capable of flanging or flaring steel and stainless
tubing with a few simple operations. And since each die has
flanging tooling on one side and flaring tooling on the other,
you only need one die to perform both functions. In addition,
because of its adjustable tube stop, the ECO 25 does not require
a different die for each wall thickness of tubing – just one die for
each tube outside diameter.
Portable
The ECO 25 has handles on three sides of the machine, making
moving it around the workplace an easy task. It can either be
set on its rubber feet or, for a more permanent location, bolted
to a work bench or cart.
90˚Flanging
The ECO 25 is capable of completing 90° flanges on steel and
stainless steel tubing from ¼” through 1½”outside diameters for
use with O-ring Face Seal tube fittings, such as Parker Seal-Lok™.
37˚Flaring
The ECO 25 is capable of completing 37° flares on steel and
stainless steel tubing from ¼” through 1½” outside diameters for
use with JIC 37˚ flared tube fittings, such as Parker Triple-Lok®.
Hydraulic Pump
The ECO 25 is easily operated using a hand hydraulic pump,
allowing it to be utilized virtually anywhere.

Tube End Preparation
Tube end preparation is one of the most critical processes in
obtaining an optimum seal of a flanged or flared tube end con-
nection. Regardless of the tube material, similar guidelines for
tube cut-off, deburring, and cleanliness can help assure the tube
to fitting connection remains leak free.
Tube Cutting
• It is critical that the tube be cut squarely within +/- 1° in order
to assure the proper tube to fitting connection. A tube end
which is not cut squarely may result in a flange or flare which
is not circular, potentially causing leakage.
• When cutting tube in preparation for flanging or flaring, a saw
which utilizes a toothed blade is recommended. This type of
tool will assure that the tube end is not hardened from exces-
sive heat or cold working of material.
Recommended
Low speed Circular Saw, Hacksaw
Not Recommended
Rotary Tube Cutter, Abrasive Saw
Tube Deburring
• Deburring the inside and outside diameter of the tube end is
necessary to assure the tube fits properly inside the flange
or flare sleeve. In addition, proper deburring of the tube end
is necessary to form a flanged or flared tube end which is
free of imperfections that may create a leak path between
the tube and fitting. Improper Cut

Step 4: Raise the tube stop and install the flanging pin into the
main spindle head of the machine. Be sure to lower
the tube stop to its original position after inserting the
pin.
Step 5: Using the LB-2000 lubricant for steel or Pro-Form 858
lubricant for stainless steel, adequately lubricate the
flanging pin as well as the inside diameter of the tube
end. It is very important to lubricate the Flanging
Pin and Inside Diameter of the tube end prior to
each flanging operation.
Step 6: Insert the bottom half of the die set (either die half can
be used) into the die cavity of the machine using the
keyways on either side to secure the die. Ensure that
the 90° Flange side of the die half is facing toward
the main spindle head of the machine (away from
the operator).
Step 7: Place a Parflange mechanical sleeve (part number
TPL) onto the end of the tube with the widest part of the
sleeve facing the end of the tube you intend to flange.
Place the sleeve and tube assembly into the bottom
half of the die set, ensuring the Parflange sleeve is
placed into the corresponding cavity in the die half.
Step 8: Insert the top half of the die set into the die cavity on
top of the other half, also ensuring that the 90° Flange
side of the die half is facing toward the main spindle
head of the machine.
Step 9: Set Tube Stop adjustment dial to recommended value
for flanging the O.D., wall thickness and material of
the tubing you are using (See Chart on page 8). Dial
settings are recommendations only and may require
adjustment to obtain desired results.

Step 10: Set Head Stop adjustment dial to recommended value
for flanging the O.D., wall thickness and material of
the tubing you are using (See Chart on page 8). Dial
settings are recommendations only and may require
adjustment to obtain desired results.
Step 11: Close swing arm against shoulder bolt.
Step 12: While keeping tube end against tube stop, rotate clamp
vise arm clockwise and securely clamp tube in die
set. Be sure to properly support long tubes during the
clamping and flanging process.
Step 13: Note: Look up the recommended flanging pressure
for the O.D., wall thickness, and tube material you are
using from the chart on page 8.
Step 14: Press and release green start button on front of machine
to start rotation of main spindle head. If head does not
rotate upon activation of motor, check electrical con-
nections and retry. Be sure to use an electrical outlet
with 110V/20A power.
Step 15: Ensure the tube is held in position and slowly actuate
the hydraulic hand pump. The flanging pin will come
forward and the tube stop will automatically rise up and
away from the tube. The pressure gauge will show a
rapid rise in pressure as the pin engages the tube end
and flanges the tube.

Step 16: When the pressure gauge reaches the recommended
flanging pressure from Step 13, de-energize the hy-
draulic power supply. This will allow the flanging pin
and spindle head to retract to their original position.
Step 17: Press the red stop button on the front of the machine
to stop rotation of the main spindle head.
Step 18: Rotate clamp vise handle counter-clockwise to loosen
clamp from die set and tube and open swing arm to
expose die halves.
Step 19: Remove the top half of the die set from the die cavity
and set aside.
Step 20: Remove flanged tube from bottom half of die.

Step 21: Inspect flange to ensure proper surface finish. Mea-
sure the flange diameter and compare to values in
chart below.
Adjusting the ECO 25 to compensate for
over/undersized flange diameters
If the flange diameter of your ECO 25 tube assembly is not
within the diameter specifications listed, please complete the
following steps:
• First, check to make sure that the correct flanging pin and die
set are being used for the outside diameter, wall thickness,
and material tubing you are using. Keep in mind that each
Die Set can be used with every wall thickness of that size
tubing and also with both carbon and stainless steel tubing.
However, the flanging pins are specific to the outside diameter,
wall thickness, and material of the tubing.
• Once the tooling and tubing have been verified, the correct
method of increasing or decreasing the diameter of the tube
flange is to alter the Head Stop adjustment dial (do not change
the Tube Stop adjustment dial setting).
• To increase the diameter of a tube flange, adjust the Head Stop
adjustment dial Clockwise (dial setting number will increase)
a small amount and repeat the flanging process. If the desired
result is not achieved, repeat adjustment process as needed
until the proper sized flange is made.
• To decrease the diameter of a tube flange, adjust the Head
Stop adjustment dial Counter Clockwise (dial setting number
will decrease) a small amount and repeat the flanging process.
If the desired result is not achieved, repeat adjustment process
as needed until the proper sized flange is made.

Step 1: Measure the tube O.D. and wall thickness for proper
die and pin selection.
Dual Function Die Set
Step 2: Select the die set and flaring pin matching the tube
O.D. and wall thickness of your tube from the chart on
page 7. The die set is stamped with the tube O.D. and
the pin is stamped with both the tube O.D. and wall
thickness.
Step 3: Open the swing arm to expose die cavity and main
spindle head.

Step 4: Raise the tube stop and install the flaring pin into the
main spindle head of the machine. Be sure to lower
the tube stop to its original position after inserting the
pin.
Step 5: Using the LB-2000 lubricant, adequately lubricate the
flaring pin as well as the inside diameter of the tube
end. It is very important to lubricate the Flaring Pin
and Inside Diameter of the tube end prior to each
flaring operation.
Step 6: Insert the bottom half of the die set (either die half can
be used) into the die cavity of the machine using the
keyways on either side to secure the die. Ensure that
the 37° Flare side of the die half is facing toward
the main spindle head of the machine (away from
the operator).
Step 7: Insert the top half of the die set into the die cavity on
top of the other half, also ensuring that the 37° Flare
side of the die half is facing toward the main spindle
head of the machine.
Step 8: Rotate the Tube Stop adjustment dial clockwise until
it cannot be adjusted any further (dial should read ap-
proximately 0150). At this point, the tube stop should be
in contact with the back side of the die set, but please
ensure it is not pressing against the die set too tightly,
as this can damage the machine. The aim is to line
up the tube end flush with the back side of the die set.
This process will be the same for every size and wall
thickness of tubing used.
Step 9: Rotate the Head Stop adjustment dial clockwise until
it cannot be adjusted any further (dial should read
approximately 0275 but it may be slightly higher or
lower). The aim is to get the head stop out of the way
of the spindle head travel, as it is not necessary for
the flaring process. This process will be the same for
every size and wall thickness of tubing used.

Step 10: Insert the tube through the die set until it touches the
tube stop. You may have to raise the upper die half
slightly to allow the tube to fully insert through the die
set.
Step 11: Close swing arm against shoulder bolt.
Step 12: While keeping the tube end against the tube stop, rotate
clamp vise arm clockwise and securely clamp tube in
die set. Be sure to properly support long tubes during
the clamping and flaring process.
Step 13: Note: Look up the recommended flaring pressure for
the O.D., wall thickness, and tube material you are
using from the chart on page 15.
Step 14: Press and release green start button on front of machine
to start rotation of main spindle head. If head does
not rotate upon activation of motor, check electrical
connections and retry. Be sure to use an electrical
socket with 110V/20A power.
Step 15: Ensure the tube is held in position and energize the
hydraulic power supply. The flaring pin will come forward
and the tube stop will automatically rise up and away
from the tube end. The pressure gauge will show a
rapid rise as the pin engages the tube end and flares
the tube.

Step 16: When the pressure gauge reaches the recommended
flaring pressure from Step 13, de-energize the hydraulic
power supply. This will allow the flaring pin and spindle
head to retract to their original position.
Step 17: Press the red stop button on the front of the machine
to stop rotation of the main spindle head.
Step 18: Rotate clamp vise handle counter-clockwise to loosen
clamp from die set and tube and open swing arm to
expose die halves.
Step 19: Remove the top half of the die set from the die cavity
and set aside.
Step 20: Remove flared tube from bottom half of die set

Adjusting the ECO 25 to compensate for
over/undersized flare diameters
If the flare diameter of your ECO 25 tube assembly is not within
the diameter specifications listed, please complete the follow-
ing steps:
• First, check to make sure that the correct flaring pin and die
set are being used for the outside diameter, wall thickness,
and material tubing you are using. Keep in mind that each
Die Set can be used with every wall thickness of that size
tubing and also with both carbon and stainless steel tubing.
However, the flaring pins are specific to the outside diameter
and wall thickness of the tubing.
• Once the tooling and tubing have been verified, the correct
method of increasing or decreasing the diameter of the tube flare
is to alter the flaring pressure used during the flaring process.
• To increase the diameter of a tube flare, repeat the flaring
process as before, but utilize a slightly higher flaring pressure
than noted in the charge on page 15. Continue this process until
the flare diameter is within the specifications listed to the right.
• To decrease the diameter of a tube flare, repeat the flaring
process as before, but utilize a slightly lower flaring pressure
than noted in the chart on page 15. Continue this process until
the flare diameter is within the specifications listed to the right.
