TurnPro indexing tube benders are available in sizes to bend
1/4, 3/8, and 1/2 in. and 6, 8, 10, and 12 mm OD tubing. The
size of the tube bender is indicated on the face of the tube
bender near the alignment marks.
Selecng Tubing
Leak-ght connecons require high-quality tubing which
meets requirements for material hardness, roundness/
ovality, and wall thickness. The tables #1, 2, and 3 contain
suggested specicaons for fraconal and metric tubing.
Tubing Hardness
Read this manual before using the
TurnPro Tube Bender.
Tube Bender Components
TurnPro Indexing Handle Tube Benders provide consistent,
high-quality bends in stainless steel, carbon steel, nickel al-
loys, and other tubing materials used with SSP tube ngs.
The components of the tube bender are named in Figure #1.

Metric Tubing Wall Thickness
Tubing Installaon
When bending tubing, it is important to allow a sucient
length of straight tubing between the shoulder of the tube
ng and the bend. ( See Figure 2)
Tables #4 and #5 specify the minimum required lengths for
straight tubing leading into a tube ng for each tubing OD
and bend radius.

In this secon, you will learn methods to plan, measure, and
mark tubing.
Sequenal Bending Method
In this method, users measure, mark, then bend each leg of
the fabricaon in a sequence unl the project is completed.
The steps are:
1. Add the lengths or all secon together to calculate the
overall length of tubing required for the job.
2. Mark the starng point (reference mark) for your project.
Hint: Remember to make all marks completely around the
tube.
3. Measure from the reference mark to the vertex of the
rst bend. The vertex is the point where the center lines
of the two legs of the angle meet. (See Figure 3)
4. Bend the tube using the direcons on page 9.
Table #4
Table #5

5. Using the vertex of this bend as the reference market for
the next bend, repeat steps 3 and 4 to complete the next
bend.
6. For addional bends, use the vertex of the previous bend
as the reference mark, repeat steps 3 and 4 for the next
bend.
Example
A 90° bend 4 inches from the reference mark followed by a
45° bend with 4 inches between bends .
Example Steps (see Figure #3 above)
1. Place a reference mark at the start of the tube.
2. Make the bend mark 4 inches from the reference mark.
3. Bend the tube 90° (See the instrucons on page 9).
4. Make a second bend mark 4 in . from the center line of
the rst leg.
5. Mark a point on the reference mark indicang the outside
of the bend. (See Figure #4)
6. Using the direcons on page 11, bend the tubing 45°.

Tip
Mark the outside of the
bend to make the next bend
easier to align.

Laying Out Oset Bends
Oset bends change the centerline of the tubing run to
avoid an obstrucon.
To determine the distand between bend marks in an oset:
1. Determine the oset angle and locate it in table #6.
2. Mulply the oset bend allowance from table #6 by the
oset amount.
3. Use the oset calculaon as the distance between the
marks.

Example
Calucate the vertexes for the diagram below for 1/4 in. tube
bender with a 9/16 in. bend radius.
Figure #7
Figure #6
Example
Oset bend angle (E) 45°
Oset Dimension (O) 3.50 in .
3.5 x1 .414 = 4.94 in. or approximately 5 in.
Adjustment (Gain) Method
The Adjustment or Gain Method measures and marks the
enre layout for a project prior to bending using adjustment
or gain factors. Gain is the amount that tubing stretches as it
bends. See the adjustment tables to determine the amount
of gain for each tube OD, bend radius and bend angle.
8
Adjust Method Example Steps (refer to Figure #7)
1. Mark the tubing for the rst vertex
P1= 3 in.
2. Calculate the second vertex mark by adding the second
leg to the rst then subtracng gain factor for the rst
bend. Use Table #7 and 8 to nd the gain factor. At the
top of the table locate the tube OD and bend radius, then
read down to the bend angle to nd the gain factor.
P2 = P1 + 3.5 in. – 5/16 in. adjustment = 6 3/16 in.
3. Follow the same procedure to caluclate and mark the
second bend.
P3 = P2 + 3 in. – 5/16 in. adjustment = 8 7/8 in.
8 7/8 in. is the total length of tube needed.
