Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Amazing sealant Excellent sealant, also general silicone glue. Easy to use, strong smell but excellent leak stopper

Rated 5 out of 5 by from Easy to use, works well Works a treat even in a fairly high pressure application. It looks and behaves for all the world like bathroom sealant, so I would think you could use that instead if you happen to have some spare in your caulking gun, but otherwise yeah, easy to use and works very well.

Can this be used to stop a leak on a Fernox TF1 Filter

I have a Fernox TF1 Filter, its leaking from the top despite changing the rubber O ring. Could I put a bead of this leak sealer around the top where the O ring sits, fit the lid and tighten the cap of the TF1 Filter to stop it leaking?
Asked by: Rich05uk
We would no advise using leaker sealer on any of the threaded joints on the TF-1 Filter. Ensure the seal faces are clean and that one O-ring has not been pinched or mis-sharpened on tightening. Finally ensure the correct torque has been applied to the seal, with the alignment of the lid marker.

Can this be used to seal around an immersion heater?

Asked by: Klvn
We can confirm that this can be used on the threaded joint for an immersion heater. Apply to the male thread, make the joint up, and allow at least 4 hours to cure before refilling and pressurising.

Can LS-X be used to repair a leak on a plastic water butt

Asked by: Beardman
Hi Beardman, Yes, but you will need to get the contact surface dry and leave the LS-X for 2-3 hours to cure off before putting it under pressure

Will this stop hot tub pipe from leaking

Asked by: G6rbl
Hi, Sorry for the very slow reply but I was not notified that there was a question, yes you can use LS-X for this. Dry the contact surface, apply a layer of LS-X, bind round with PTFE tape, layer again with LS-X, leave for 2-3 hours before applying pressure and you will have a permanent water proof flexible seal.
