Answer:
The hex head will outlast the bolt threads and wedges, as long as you use a properly fitting impact socket. I use this to occasionally stretch exhaust tubing, and it will last me almost forever. If you were to use this 10 times a day in a muffler shop, expect it to break within 1-3 months.

Answer:
Yes they have rubber rings around them. I don't think heating the pipe is necessary. Just need a decent rattle gun and keep the threat well lubricated.

Answer:
There are two black dies one is on the expander in the pic, one is in the lower left corner. You can use either one of those on the expander by themselves, for the smallest of pipe sizes.
The silver dies are to be used in conjunction with the black dies to expand the larger of the pipe sizes.

Answer:
I don't know about this particular tool, but I've had stainless tubing of around 16ga, 2.25" ERW expanded at muffler shops on their hydraulic machines for a slip fit onto itself. No problem at all, no heating needed either. Now, bending it is something else.

Answer:
I don't recall - but I use my Greenly hydraulic conduit punch pump with it, the threads/bolt is the same. It threads right on the pump makes it work smooth as silk.

Also remember there is a limit to how much you can stretch… see more I don't recall - but I use my Greenly hydraulic conduit punch pump with it, the threads/bolt is the same.

Answer:
I do not think so. It says on the instructions 2 7/16 inch. I did not need to go that big, so I have not tried it.
