Just be careful here to what looks like a "Tubing Bender" at those places.
There is a difference between a Tubing Bender and a Pipe Bender.
Tubing is measured in Outside Diameter, while Pipe is measured in Inside diameter.This means 2" Pipe may have a 2-1/4" OD or better. so, as you can see the dies will not work for Tubing. You can try, but all you'll do is mar and deform the tubing as you try to bend it.
Another thing to consider is the radius of the dies of a true tubing bender. too large of a radius, and you won't get the bend as tight as you expected.
More than meets the eye.... =-]'
