"Always have a bit of this on your van. It has got me out of trouble many on times on weeping compression joints and other things . Remember to put the top back on straight away because it goes off very quick."
"I swear by this stuff. I wouldn't attach a brass compression fitting without first smearing a bit on the pipe and i've never had a bad joint yet. I've also used it along with ptfe tape to attach every rad valve in my house when I changed the rads with no probs. Its safe for aquatic use too so fine for drinking water pipes as well as central heating pipes. I even used it to seal a crack on a plastic fish tank a couple of years ago and the fish is still going strong."
"I had read all the reviews about this and thought I had better buy some, as a 1st time woman DIYer I highly recommend it, its easy to use and yes it stops the leaks a wonderful product that everyone should keep in their tool box."
"i am replacing a new radiator,which is wider than the old one and bent the compression bit of the valve,causing very tiny leaking. was thinking need to cut the olive off and put on a male compression connector. but.....ls-x helped nd sorted out everything,saved a lot of trouble. this is my first review on housing working stuff.Really helpful product."
"I had a new rad spigot that would not seal despite miles of ptfe tape. Tried it twice and still leaked. Took spigot out, dried it, liberal amount of LS-X on threads and smeared round exterior as well. Left for 12 hours and joint is fine. I'd recommend and will def be using it from now on. Anyone want some ptfe tape?"
"Have been using this instead of ptfe for a few years now and its always gives a ood seal without making threads difficult to undo and reuse, it can get a little messy but cleans off your hands fairly easy."
"This is an excellent product, i've been using it for years on many jobs and keep finding more uses for it. Firstly, i, like many others have sometimes had trouble making good joints with PTFE tape and having to dismantle a joint just to rewind tape is time consuming and annoying, I have NEVER had a failure from a joint whilst using this product, that alone makes it value for money. Secondly. Some people have noted that the cap can be a bit fragile, cracking or breaking completely when tightened, if air gets in you're going to lose the whole tube, I have found that an old tooth paste cap works well as a replacement, in fact i've reused the same replacement cap for some time now. Finally, I recently needed to slide a tight rubber sleeve on to a soil pipe and had run out of silicone spray, I used the Fernox LS-X as a lube which then set to help seal the joint. Simples"
"i always carry a tube of this sealant in my tool box as it has been a god send in mending not only water leaks from pipe joints etc, but for many other jobs as well, it's flexible so will give just enough as not to give way, yet solid enough when dried to hold all sorts of thing in place, as it can be used just like glue for many jobs to numerous to say here, just try it your-selves and see,"
"Found this sealant a number of years ago. Very effective when used in conjunction with compression fittings -do not use with PTFE tape. Good for sealing waste plugs into the bottom of baths and sinks etc."
