Fernox LS-X Leak Sealer 50ml
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.

LSX the wonder sealer
Brilliant stuff. I use it on all non soldered copper joints and many plastic ones. It is excellent for sealing some difficult joints like flexible pipes on pond construction. Be careful to keep the cap and screw thread clean or the stuff will dry up quite quickly. A little expensive for what it is but is does the job extremely well and remains flexible. If you should need to break the joint open in the future the stuff peels off easily ready for another application before tightening the joint again.

Have used this over the years to prevent, or stop, leaks in joints in the water pumping and filtration system on our garden pond and it has always worked.
In addition it easy to remove when you disassemble. It looks very much like clear silicon sealant, but this is far more effective.

It's never let me down
I've now been using LS-X across any number of plumbing applications for years and this compound - because contact with water helps it cure - has never let me down. If I want to be doubly sure that a foam ring or neoprene washer is properly seated and secure, I always add a ring of LS-X. You can't go wrong and you save yourself an awful lot of time and repacking seals.
