Flanging Information for Seal-Lok Fittings
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.
