For bending tools, I started out with that Eastwood triple head bender on my first build. I didn’t feel like it worked all that well. At least for me. The handles are pretty short, so for 3/8 SS I was using for fuel lines was literally almost more than I could do to bend. I’ve since settled on these three dedicated size benders. All work very well. Ridgid provides decent benders that are better IMO than the average run-of-the-mill benders. Not Swagelok quality, but a fraction of the cost. I use a Ridgid 36097 3/8-inch, Ridgid 36117 3/16-inch, and a smaller 3/16-inch bender from InLine Tube. It does an even tighter radius when that's needed. All highly recommended. Here are pics of each and the bends they make in SS. Huge fan of the Eastwood flaring tool. Used on all my builds. Not a fan of the pinch type benders. Have one (came as a set with the Eastwood triple header) and used it once. Has a purpose I guess, but knicks up the line so not my preference.
