Fernox LS-X Leak Sealer 50ml is rated 4.6 out of 5 by 234.
Rated 5 out of 5 by from Lifesaver Used this product on an over tightened shower valve that had a slow weep. Tried ptfe, then more ptfe with no luck. Ls x worked first time. Will probably use it on any compression joint in future

Rated 5 out of 5 by from Saves time. More expensive than ptfe tape but much quicker and easier to use. Used it regularly in the last 10 years. Stops having to put a small fortune in the swear box.

Rated 4 out of 5 by from Good product. ..but Works well, but please Fernox do something about that awful cap which despite careful replacement will split in your toolbox and make contents useless. Especially relevant to DIY users with occasional use. 2 3/4 tubes thrown away.

Rated 5 out of 5 by from Great Product Brilliant for sealing weeping joints. Also great for those joints that end up getting hidden in stud walls / under the floor - no worries about it weeping un-noticed.

Rated 4 out of 5 by from Great leak sealer This product stopped a leak on a hot tank outlet union at 2.5 bar when all else failed.

Rated 4 out of 5 by from Excellent Product Very Good. Perfect for stopping those little drips under the bathroom sink. Also used it to apply on PVC press fit joints and PVC threaded connections. This product cures but never actually hardens which make it easy to disconnect at a later date whilst providing a watertight seil. Only issue is it is a bit pricy for a small tube but maybe worth it as no leaks to worry about.
