Spring Tube Bender Manufacturer,Supplier and Exporter in India
Product Code : EL-AELE-12907
Jlab Export is a leading Spring Tube Bender Manufacturer,and suppliers in India
Spring tube benders let soft copper be bent by hand without crimping or collapsing the wall. The spring slides over the tube and supports it from outside through the whole bend. These benders are made for thin-wall copper pipe of 1/4, 5/16, 3/8, 1/2 and 5/8 in OD, and they bend it to any angle up to 180 degrees.

Tube Bending Exercises for Students
A good first exercise is a set of three bends in one tube: a right angle, an offset and a U-bend. Students mark where each bend starts, slide the right-size spring along to the mark and bend the tube slowly over the thumbs or knee. The spring is then eased off by twisting it along the tube.
The bends are checked next. Students measure the tube across each bend with a Digital Caliper in two directions, which shows how far it has gone oval. They repeat the same bends with the Ratchet Tube Bender Kit and compare the radius, the ovality and the time each method takes.
Frequently Asked Questions
Which spring goes on which tube?
Use the spring that matches the outside diameter of the tube: 1/4, 5/16, 3/8, 1/2 or 5/8 in. The tube should slide in with little play. A loose spring lets the wall flatten, and a spring for a smaller size will not go on at all.
Can it make a U-bend?
Yes. The benders take thin-wall copper round to 180 degrees without crimping, so a full U-bend can be made by hand. Form it gradually along the length of the spring rather than in one sharp pull.
What if the spring sticks after bending?
Open the bend a fraction to loosen the grip, then twist the spring as you pull it along the tube. Keeping the bend within easy reach of a tube end also makes the spring quicker to remove.
How should the tube be held while bending in the spring?
Press down on the spring near the bend with one hand and lift the tube end with the other. Work along the spring a little at a time rather than pulling at one point. That spreads the bend and keeps the wall round.
