Review: Excellent simple expander. Get the job done. - I used the expander to expand a 3/4" HVAC copper tube for fitting. The two ends of the tool have different sizes. One size is slightly bigger than other. Use the small side to expand the tube. The expansion is not done by a single press. Need multiple pressings and turn 90 degree each time. It makes the opening wider and wider. When one side is done. Flip the tool use other slightly bigger size to expand the opening again. Repeat the multiple expansion steps. Then, get the 3/4" fitting to other 3/4" tube :) It takes time, but works !! I've encountered an AC coil inlet size slightly smaller than the tube. Use the expander to expand it. Snug fit, excellent !
Review: Sturdy and works well! - I have used this a few times now with great success. Yes, you must rotate the pipe while swaging to maintain a round cross-sectional shape. And, those who complain about split pipe are probably attemtpting to swage hardened (tempered) copper tubing used for water lines. Swaging must be done on soft copper. An end (say ~ 2 inches) of hardened copper can be annealed (softened) by heating with an ordinary propane torch to a cherry red color and then quenching in water. Be aware that "working" copper (via bending, hammering, swaging, etc. also "work hardens" (tempers) the material. However, merely swaging the end of a copper tube does not constitute enough "work hardening" to cause breakage. If the tube is rigid, as for water, it has been hardened and will need to be annealed before swaging to prevent splitting while swaging. That is not a big deal; just heat the end to be swaged with an ordinary propane torch and then dip in room temperature water to quench. After that process, the end to be swaged will be "annealed" and soft enough to swage. After swaging it will be ready to solder. For those unable to finesse the "rotating while expanding" part of the process to achieve an acceptably concentric tube end, I suggest using a tube flaring and swaging kit, many such kits also available here on desertcart. (I have one from Wostore that is very nice, is economical, and does both swaging and flaring. In that case, you lock your tubing into an appropriately-sized hole in a steel swaging bar, install an appropriate-sized swaging die into a swivel connector on a steel yoke (yoke is a type of clamp that locks onto the swaging bar) and then turn a handle to screw the swaging die into the inside diameter of the copper tubing to expand it. The latter method obviously takes many more steps and is thus much slower than using the swaging tool of this listing, but the die makes a perfectly symmetrical expansion without artistic finesse from the user. I believe that most of the problems expressed by frustrated reviewees stem from attempting to swage tempered (hardened) copper without annealing. The video by the seller is not helpul at all and probably adds to the confusion. He appears to be doing the process at breakneck speed to impress would-be buyers with how quickly swaging can be done using his tool. However, the undesirable result is that one can hardly see that he is rotating the tube while he works to maintain a symmetrical expansion. He probably receives many returns as a result, when a purchaser simply inserts the tool into a piece of tubing, squeezes the handle and is disappointed with the asymmetrical result. If the tubing is tempered, both an asymmetrical and split cross section can result. So much confusion due to poor communication, so little time...

## Questions & Answers

**Q: Can this tool be used to reshape an out of round copper pipe?**
A: I have not used it that way, but presume it would. You may want to try a technique that uses an adjustable wrench set to the pipe OD and rotate it around the warped section. Hope this helps.

**Q: Came with any case or cover?**
A: Just the package it came in no case or cover it does a fine job

**Q: What kind of copper can it expand. Does it do more than soft copper such as L copper?? Thanks**
A: Yes but it’s a bit hard. But if you are just soldering instead of brazing, stick to couplings and reducers.

**Q: Need to go from 1/2 inch to 3/4 inch inside diameter for copper pipe to fit in kohler fitting. Is this what I need?**
A: this tool will do the job but it will be less expensive just to buy a 1/2 to 3/4 copper fitting.

Works pretty good for expanding tubing but you wont have a great jump in size
