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 4 out of 5 by Fernox LS-X Leak Sealer Bought this item for a small central heating leak, used in conjunction with brass capillary fittings on 22mm copper pipe, No Leaks!! When applied appeared to be very similar to normal clear silicon sealer, easy to apply and does what it says on the box. 16 Jul 2014
Rated 1 out of 5 by Not What it Says I know other people swear by this product so maybe my experience is out of kilter, but about as much use as a chocolate fireguard. Just do the job properly and don't bodge it with this stuff. 10 Jul 2014
Rated 5 out of 5 by Great stuff sealed an external leek very well, used plumbers tape and this glue in layers. would use again, keeping a tube on site now. 18 Jun 2014
