Fernox LS-X Leak Sealer 50ml 4.7 5 103 103
Fernox Leak Sealer This product performs excellently for jointing BSP fittings as well as sealing 'old' weaping joints. A must have for all tool boxes! It is silicone based but the fittings are watertight immediately so you do not need to allow time for the paste to cure. NOT FOR USE ON GAS FITTINGS. 12 Oct 2011
Good product Expensive for 50ml of product, quite viscous in use and therefore a little awkward to work with - but performance is excellent. 11 Jul 2015
Perfect for leak free basins Ideal for sealing all types of sanitary ware. Seals wastes in metal sinks really well because it stays flexible. Any excess can be easily cleaned off with Big Wipes. 20 Jun 2015
Weeping immersion heater After three go's at fixing a weeping immersion heater that had been seeping for many years looking at the limescale around it, and thoroughly cleaning it each time, using a new gasket and only a little PTFE tape on the thread to lubricate, I finally decided to try LS-X. Drained it down again, a thin smear around both sides of the gasket (using the thin brown hard fibre type this time as opposed to the thicker softer ones} and after a week not a drop. Perfect seal, no dampness at all around the boss which is something I couldn't achieve before. So I am sold on LS-X . I am an old SEEBOARD electrician and in the 60's we used to fit loads of immersions using the brown fibre gasket and Boss White in those days, but as is said elsewhere difficult to get out again. 14 Jun 2015

I have a weeping joint where the central heating pipe connects to the radiator. I don't really want to drain the pipework down to dismantle the joint. Will this product work by wiping it over the leak?
