pre-soldered copper fittings

Does anyone have any experience with pre-soldered copper fittings? Do they work properly, are they as strong?

Do a Search in the archives for previous questions/answers about these.

I don't see it. I did a search and saw mention of pre-soldered fittings but no actual reply. (They were mentioned relating to resoldering and using something called "just for copper.") If anyone has feedback on these it would be greatly appreciated.

They work but if you overheat them they will require the roll of solder close by. If you use the proper heat they work fine. Never use a turn brush inside of those fittings; they say not to but I beg to differ since aging copper will tarnish inside of them, requiring the turn brush. I never pull away from the etched in stone rules of correct soldering of copper.

Our Home Depot has pretty much switched over to them, so I tried them when I replaced the old plumbing in my house a few months ago. I was *very* pleased with them. They flow with less heat than conventional solder. Put a turbo torch on it for a few seconds and a nice wet band of solder appears around all joints in a flash. I did not have to touch up any of them. I do use plenty of flux, I like Oatey, although my wife works for Oatey
