We created this page to help you design and manufacture bent tube! Let us know what else you would like to see a calculator for!

Bend In The Middle Calculator

Bend In The Middle Calculator - Clamp Block Distance

Bend in the Middle Calculator

This will tell you how to put a bend in the center of a piece of tubing! No math skills required. Forms are pre-filled with the exact numbers from our sample image so you can see where to plug in your numbers. This form outputs in decimal, so keep a fraction chart handy if you're going to use a tape measure to lay out your tube.

Leg Length

How long will the straight parts be? Look at the picture to see what this means. If you have a piece of tube/pipe a certain length and want to bend it in the middle (and you don't care what the leg lengths are, as long as they match), just type in numbers here until your "cut length" below is the length of the chunk-o-pipe sitting on your floor. Easy!

CLR (Center Line Radius - "Bend Size")

3.5", 4.5", and 6.0" Are Common

Degrees Of Bend

HIDDEN - Bend Offset

Cut Length (How Long to Cut Your Tubing)

Note: This assumes NO Tube Stretch

Clamp Block Distance From End of Tube. Blank = Choose a common CLR!

Note: Assumes a 0.6% Tube Stretch. If you have a negative number here, a longer "leg length" is needed!

Bend Start (From End of Tube)

This is helpful if you are using a bender from JD2, Protools, Baileigh, etc.
