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 Great sealer Great sealant, better and easier to use than PTFE tape. Has proven reliable and easy to apply over and over again. 27 Jan 2016
Rated 5 out of 5 by A must have Great product that has got me out of many a sticky issue. Used to seal syphon to toilet cistern - worked a treat. also used this to provide a thin invisible seal around the rear lights on a classic car. Totally invisible yet stopped a leak into the boot that I've had for years. At this price, you can't afford not to have this in your tool box. 20 Jan 2016
Rated 1 out of 5 by not easy to apply to a basic novice (basically me) this didn't stop a leak it just directed the water to another spot and wasn't great under the pressure of the water, i guess it could be user error but i would just recommend replacing whatever part is leaking asap. 31 Dec 2015

The leak is definitely coming from the plug/trap area but I didn't want to start putting loads of sealant on if you're not supposed to. Also, if the paste is suitable, do you use the same amount as silicon? It's a ground floor shower with a slimline trap.

Answer: 
Hello Denise. If you are just sealing a leak in the washer, LS-X would work fine as it is a high quality leak sealer. A small amount should be sufficient, but please refer to the instructions when applying to get the best results.

Hope this helps.

Answer: 
Hello Lyngst, you can use LS-X leak sealer, however the radiator needs to be drained and dry in order for LS-X to key to radiator. You may find it easier to use our F4 Leak Sealer 500ml or Express, as this can be added to the system via the radiator or header tank and will stop pinhole leaks.

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?

Answer: 
Hello Ocheok. Unfortunately this will not work, as LS-X needs to key to a dry surface for half an hour before curing. Instead, try either our Leak Sealer F4 500ml or Express, as this is designed to stop weeps and pinhole leaks without needing to dismantle or drain down the system.
