Very minor boiler leakages.

use 290 , wick-in 68.72.74.113/PRODUCTS/290.htm

I had leak on my mud ring, on a 5" hunslet, copper boiler..(the leak)Intially it worked for about 3 mths, then would'nt seal after that, last about 4hrs under steam, then let go, did that a couple months in a row, then ended up removing bolier anyways, and putting a layer of soft solder, took a few goes, as it would leak near by, (after pressure testing with water), reheat, reapply, test, leak a little over there, reheat, test etc.....but got there in the end, no more leaking

(a quick stop measure, put a little pepper, teaspoon in the boiler, this got me through a convention weekend, when I was 2000km away from home)

Mustard is very good too. We also used to use it years ago to cure radiator leaks in the old wrecks that we used to drive.Put it in, steam up, blow down.

this is probably what you are after, unless this is where you got the idea from in the first place.

In my humble opinion Loctite may work provided the area treated and the hole is absolutely clean otherwise forget it .

I've just noticed this and I have this problem. I'm planningto clean off the residual flux using an ultrasonic cleaner and was going to then reheat in the affected areas - but Loctite 290 sounds a great deal easier!

I hope I have not caused any problems with the thread, but having got at least one answer that met with my request I made an attempt to close the thread down. Finding of course it does not work quite that easily.

However I do realise that cleanliness is one of the main criteria, as with everything, any attempts to try this would be probably as a last resort after a lot more investigation in the areas surrounding the initial problem. The ideas of using any form of repair that demands substantial reheat is out of the question as many of us will have found to our dismay, you end up chasing a small leak all around the boiler making everything possibly worse.

I will chew things over and then decide just what to do, by the way it is not my own boiler, it belongs to one of our own club members, thanks to all.
