Introduction
Swagelok®hand tube benders provide consistent,
high‑quality bends in tubing made from most materials
used with Swagelok tube ttings.
Read this manual before using the hand tube bender.
Tubing Data
■ The Swagelok hand tube bender bends 1/8,
1/4, 5/16, 3/8, and 1/2 in., and 3, 6, 8, 10, and 12
mm outside diameter tubing in a variety of wall
thicknesses.
■ Tubing should be free of scratches and suitable for
bending.

Tubing Installation
Properly selected tubing, combined with quality
Swagelok tube fittings, can provide leak‑tight
systems.
When installing fittings near tube bends, there must
be a sufficient length of straight tubing to allow the
tube to be bottomed in the Swagelok tube fitting:

Vise Clamp Block
The Swagelok hand tube bender features a vise
clamp block which allows the bender to be clamped
in a vise. This feature is helpful when bending tube of
a hard material or heavy wall thickness, or long pieces
of tubing that need to be supported.

Bend Layout
This bender can be used to form single, offset, and
other bends. This section contains information for
measuring and marking the tube prior to bending.
Note: Make all marks 360° around the tube.
The Measure-Bend Method
1. Estimate the overall length of tubing required by
adding the length of all the sections together.
2. Place a reference mark at the end of the tube
from which you are beginning the measurement.
3. Measure from the reference mark and make a
bend mark on the tube at a distance equal to
the desired bend length. This mark indicates the
vertex of the bend.
4. See Using the Bender, page 12, to bend the
tube.
5. For additional bends, use the vertex of the
previous bend as the reference mark, repeat
steps 3 and 4 for the next bend. (The vertex
is where the center lines of the two legs of the
angle intersect.)
An example appears on the next page.

Example of the measure‑bend method:
A 90° bend 4 inches from the reference mark followed
by a 45° bend with 4 inches between bends.
1. Place a reference mark at the end of the tube
from which you are beginning the measurements.
2. Measure 4 in. from the reference mark and make
a bend mark to indicate the rst desired bend
length.
3. Bend the tube 90° as described in Using the
Bender, page 12.
4. Make a second bend mark 4 in. from the vertex
of the 90° bend, away from the reference mark.
5. Place a directional mark over the bend mark
to indicate the outside, or heel, of the 45° bend.
This will help ensure the bend is made in the
intended direction.
6. Bend the tube 45° as described in Using the
Bender, page 12.
