Just for Copper is a solderless bonding agent that permits the bonding of copper-to-copper and copper-to-brass without the use of solder or heat. This comes in especially handy when you have a joint located where you are not comfortable using a torch. Dry-fit your pipes, mark the joints, sand inside & out, apply a proper amount of compound, press together, twist, and you are finished. Works like a charm, even on those joints you couldn't get to hold solder.

I was surprised by this product. I've plumbed several houses, a volunteer crew leader with Habitat for Humanity, and so on. You name it, I've done a little of everything. My nephew and I were running new copper for his second bath and there was a joint that wouldn't take solder. He went to the local True Value for a compression fitting and the clerk suggested he try this bond. He brought it back and it worked. We then put in a new outdoor faucet for my mother. We were concerned with using a torch in an area that was cramped and had electric lines running through it. Using this bond took care of that concern and it worked great. Of course, the product isn't fool proof (i.e. human error), so here are some tips on how to use it.
