"Used it to seal around replacement washer leading from cold water tank. The original hole I think had been drilled a little too large, but the gel was easy to apply and set quite quickly. No leaks so far! Remember to put the cap back on promptly"
"i always keep a tube or 3 in the van excellent product and has not failed yet on stopping weeping joints on old compression fittings however a pro to a con is that its very quick to cure which is good for sealing the leak but also ends up curing in the tube if you dont get the cap on quickly"
"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."
