Rated 5 out of 5 by 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
Rated 5 out of 5 by Lifesaver Bad olive? Take it apart, cover it in this and reassemble. Works very well on heating systems up to a bar. Don't know about mains performance. Only down side is the cap which seems to let a bit of air in and harden. 21-Oct-2014
Rated 5 out of 5 by Never without No plumber should have a van without lsx. Very useful, even if the stuff will go off in the tube. 18-Oct-2014
