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 A must for a plumber Not cheap but it’s the same price of a half used full tube of silicone. Sets rapidly and guarantees leak free connections.

Rated 4 out of 5 by from Clueless reviewers Even though the product says it's an external leak sealer it isn't. so all the people who keep giving it bad reviews saying it won't stop a leak need to understand this. What this product is in fact is just a good jointing compound to be used when you are making a compression joint or threaded joint . And if used in that way it is very successful. I've always had some in my toolbox for the last 15 years.What you can't do with LSX is just smear it on the outside of fitting or a pipe which has a leak and expect it to work miracles. 'Because I'll tell you now it won't do that and it will be a complete waste of your time and money if that's all you're buying it for.The only annoyance with this product is the little cheap plastic cap which doesn't properly seal the tube once it's been opened and can actually split if you screw it on too hard. This means a lot of the product hardens in the tube. And you've wasted a lot of what is quite an expensive product For the size of the tube.

Rated 5 out of 5 by from Excellent product I had several leaks from new sink and trap fittings. I striped it down and used this gel on each piece. All leaks stopped. It works quickly and instantly. It's easy to remove when cured (with blade or rub with finger. This is a brilliant product. Highly recommended!

Recommended for Sealing 1" BSP Plastic Male to 1" BSP female brass adaptor

Should I use LS-X in preference (or in addition) to PTFE tape for sealing a 1" male plastic threaded (tapered) piece from 32mm plastic water pipe mains supply to a 1" BSP brass adaptor?
Asked by: Chrisa6
Hi Chrisa6, Because the joint is larger I would use a combination of LS-X and PTFE tape, make sure that all the contact surfaces are dry before applying the LS-X, then make the joint and leave for 2-3 hours to set before applying any pressure.

Will the leak sealer work on a pin hole leak on the bottom of a radiator

Asked by: DnA7
Hi DnA7, Yes but you will need to drain the radiator out, dry the contact surface, apply the LS-X and leave for about 3 hours before refilling the radiator.
