Ok, that's what I was after. No flux. Do you sand it clean like you would copper for soldering?

I have brazed lots of things with fluxed bronze rods. I've repaired frozen and broken water pumps this way. Just never messed with refrigeration lines. And never used silver solder. I have a tube of it that may be very old, but it's still silver solder so it should work.

Anything else I need to know before plugging the hole?

you only need to clean the pipe if it's really oxidized or if there is some tape residue. if you aren't sure you can use some sand screen on it. I looked at our local tractor supply store and the have some 1\8" brazing rod called weld-it, made by Hobart so if you can find a Hobart dealer you should be able to get it. this stuff is in a flat rod and not in a roll because the silver content makes it to rigid to roll up. If you have something that rolls up you might want to check the silver content. the stuff you get in the flat rod has a high silver content. if you use the rod and get a good weld the copper pipe will give out before the weld.

Thanks,

I think I have enough ammo to give it a try. First on another piece of copper to get used to the heat needed etc. Then I think I can get the job done.

We are probably going to have to change out the reversing valve, but I think I'll let him handle that one.
