The whole tool
Two handles, the wheel and the hook.
1/4 · 5/16 · 3/8 in tube · Bends to 180°
3-in-1 Tube Bender
Bend small tubing by hand and it flattens or kinks at the corner. This bender wraps the tube around a grooved wheel so it keeps its round shape through the bend. The wheel has three grooves, for 1/4, 5/16 and 3/8 in tube, and angle marks up to 180 degrees. Read this first: it is for soft tube such as copper, aluminum and brass, and for thin steel tube. It is not for pipe, conduit or thick-wall steel.

Round bends, not kinked ones
Bend the tube. Keep it round.
The tube sits in a groove that matches its size, a hook holds it, and the handle walks it around the wheel. Stop at the angle mark you need: 45, 90, 135, or all the way to 180 degrees.
- Three tube sizes
- Angle marks to 180°
- Copper, aluminum, brass, thin steel
How it is built
One wheel, three grooves, one hook.
Each groove is cut for one tube size, so the tube is supported on both sides while it bends. The hook at the end of the lower handle holds the tube still, and the upper handle carries a shoe that presses the tube into the groove as you pull.
Three sizes on one tool
Grooves for 1/4, 5/16 and 3/8 in outside-diameter tube, which are 6, 8 and 10 mm. The sizes are marked on the handle.
Angle marks on the wheel
Raised marks at 0, 45, 90, 135 and 180 degrees, so you can stop a bend where you want it without a protractor.
Long handles
About 10 in of handle gives you leverage, so the bend takes a steady pull rather than a hard one.
0, R and L marks
Reference marks on the link for lining up a bend measured from the right or from the left end of the tube.
Tube materials are as the maker lists them. We have not run our own bending trials.

How to use it
Pick the groove, hook the tube, pull.
-
Choose the groove
Open the handles and find the groove that matches your tube: 1/4, 5/16 or 3/8 in.
-
Seat the tube
Lay the tube in the groove and under the hook, with your start mark at the 0 on the wheel.
-
Pull to the angle
Bring the upper handle around in one steady motion and stop at the mark you need, anywhere from 0 to 180 degrees. Open the handles and lift the tube out.
Bend slowly and evenly. A fast, hard pull is what flattens tube. Mark where the bend should start before you put the tube in, because a bend cannot be moved once it is made.
Compared with the usual options
Lever bender, spring bender, or bending by hand?
Three ways to put a bend in small tubing. Here is where this one wins and where it does not.
| Feature | This lever bender | Spring bender | By hand |
|---|---|---|---|
| Supports the tube through the bend | |||
| Angle marks to stop at | |||
| Same bend every time | |||
| Tight 180 degree return bends | Hard to do | ||
| Works in the middle of a long run already in place | Needs room for the handles | ||
| Lets you choose the bend radius |
