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 Fernox LS-X leak sealer Used to resolve a leak between an industrial sink and mixer tap which had a damaged interface seal successfully.

Rated 5 out of 5 by from Leak sealer This is my go to sealant for all those annoying leaks which are difficult to access or require lots of dismantling to get to joint. Have even used it on external water butt taps to stop it leaking where seal has started to fail.

compression fittings and plastic

I am planning to use plastic pipe and compression fittings. Can I use the leak sealer to seal the olive over the plastic pipe?
Asked by: superflo
Hi Superflow, yes you can but with a compression fitting this really should not be necessary.

Re-applying on existing seal

Hi, I applied your product to fix a leak on a copper pipe joint but I missed a spot. Can I top up the exiting layer of LS-X or should I remove it and start from scratch?
Asked by: 9909
Hi 9909, You can do either to be honest, probably easier to peel of the existing layer, wrap a bit of PTFE around the pipe and coat with LS-X to form a flat surface. If just reapplying then blot the joint first so there is a dry contact surface.

Steam pipe joints

Is LS-X suitable for use on the olives of compression joints for pipes carrying steam?
Asked by: mptrade
Hi Mptrade, I think that I have already answered your question via the Fernox Technical site. Fernox products are used for LHW systems so we have done no testing for steam applications.

Will this work on a compressor air line joined

Asked by: Stan3333
Hi Stan3333, Sorry as it is not an area we would have tested it on I have no data for it so my advice would be no.
