Swagelok tube fittings . 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 .

Fully annealed, high‑quality (Type 304, 316 etc .) stainless steel tubing EN ISO 1127 or equivalent . Hardness 200 HV (90 HRB) or less . Approx Carbon Steel Stainless Steel...
Page 6: Tubing Installation
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: Tube OD Required straight tube length (see table)

Page 8: Vise Clamp Block
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...
Page 9: Bend Layout
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 .
Page 10 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 . 4 in . Vertex Reference mark 4 in . Vertex 45° 1 . Place a reference mark at the end of the tube from which you are beginning the measurements .
Page 11 Offset Bend Formula The purpose of an offset bend is to change the center line of the run, typically to avoid an obstruction . To determine the length of offset, select the offset angle (E) . Then, multiply the offset dimension (O) by the offset bend allowance (A) .
Page 12: Using The Bender
Using the Bender 1 . Swing the short handle up so it is above the bender die . 2 . Open the tube latch . Short handle Tube latch Bender die 3 . Place the tube in the groove of the bender die with the reference mark to the left of the tube latch .
Page 13 5 . Carefully lower the short handle until the roll dies rest gently on the tube while keeping the link straight and parallel to the long handle . Note: Premature bending may occur if the link is not straight and parallel to the long handle .
Page 14 7 . Align the bend mark with the mark on the roll support that corresponds to the bend angle . 15 30 45 60 75 90 Note: View the marks on the hand tube bender as a 0 to 90 scale when bending other angles .
Page 15: Making Bends
Making Bends Bends 90° or Less 1 . Slowly push the short handle down until the 0 on the roll support reaches the desired degree mark on the name plate . Note: Be aware of springback, described on page 19 . Name plate Roll support Short handle...
Page 16 Bends Greater than 90° The right‑angle design of the Swagelok hand tube bender offers maximum leverage when making bends . The bender’s unique design lets you continue using right angle leverage for bends greater than 90° . 1 . Slowly push the short handle down until the 0 on the roll support reaches approximately 90...
Page 17 3 . Swing the short handle up until it is slightly above perpendicular to the long handle . 4 . Retighten the short handle . This will provide continuous right‑angle leverage for the rest of the bend . Long handle Short handle 5 .
Page 18: Reverse Bends
Reverse Bends The Measure-Bend Method Sometimes a multiple bend layout will require that a bend be made in reverse . A reverse bend is made with the reference mark to the right of the tube latch . 1 . Align the bend mark with the marks on the roll support as follows: 90...
Page 19: Springback
Springback All tubing will exhibit springback after a bend has been completed . The amount of springback depends on the bend angle, bend radius, tubing material, and wall thickness . Experience will help you predict the amount of springback . Expect to allow 1 to 3° of compensation . Note : Verify the bend angle using a template, protractor or against a known angle to ensure the desired bend angle has been achieved .
Page 20: Determining Changes In Plane And Direction
Determining Changes in Plane and Direction When making multiple bends on a single piece of tube, make sure the bend is made in the correct direction . For bends in the opposite direction of the previous bend, align the tube with the raised short handle (plane A) .
Page 21: Adjustment (Gain) Calculations
Adjustment (Gain) Calculations When determining tube bend location, adjustment (gain) factors can be considered as an alternate way to achieve the desired layout . Adjustment is the difference in the length of tubing used in a radiused bend compared to the length of tubing required in a sharp bend, when measured from the beginning to the end of the bend .
