Hi all,
The thread has gone (i managed to overtighten it!) on my UFH manifold. The male fitting is fine. The female had a burr, created by the overtightening, which I removed. This now leaves a small (very small) leak.
I would like to just solder the two surfaces to fill the hole. I will never need to take the two apart.
I was thinking of having a go using a blow torch, solder and flux, but before I mess things up (even more) I thought I would ask the question here.
Regards,

What happens if you tin the threaded surface of the female fitting with a bit of solder? I'd have thought it might build it up just enough to seal it.
=================== It would also be a good idea to try 'tinning' a test area of the fitting (away from the threads) to see if it will actually accept solder. As far as I know some brassware (such as taps) can contain aluminium which may prevent solder sticking.

If we are talking about a threaded conector, then a few turns of PTFE tape should do the trick.

Or possibly Fernox LS-X; I used this alone on all my recent pipework and it worked a treato. (I never was much good at PTFE tape)

If it won't solder try using flux--propane torch and a small strip of roofing lead.
Most brasses solder very well. Flux - yes. Lead? Hmm. Prefer ordinary plumbers solder r 60/40 tine lead.
BUT I am not sure this is teh way to go.
IF the thread is mechanically sound, its probably better to use some sort f mastic or the PTFE as others have suggested. Solder is mechanically very weak and can tear.
There is some sort of Loctite goo that can be used to do this sort of thing.
Brass solders perfectly.
Thanks to all that have replied. There is a loctite 55 pipe sealing cord available.
I think I will have a go with the loctite. If that doesn't work I may try some two part epoxy. If that fails then I will try soldering.
I have to admit I have never been a fan of PTFE tape...
If the mechanical connection is strong, but it just leaks, I'd go for Fernox as Mike said. Brilliant stuff.
