M&L, XPRO Gripaloc Liquid PTFE Thread Locker & Sealant - 50ml | The Revolutionary Thread Sealing Liquid, Squeeze bottle and Non-Drip technology allows precise application.

Best liquid PTFE there is. Prefer it over the Rapid Blue Stuff. Much thicker and easier to apply. Make sure you shake it before use and tap base of bottle on hard surface to clean the nozzle after use.

This is so easy to use. The amount times I have had check a system find it leaks then re-apply PTFE to a joint and do it again, follow the instructions and you are good to go no unsightly tape showing either

Bit disappointed looks like it came half empty in the container

They good product and easier than tape ,Very good service Thanks

Excellent product already ordered another as a spare

A great product as I’ve used it before from another supplier but unfortunately the bottle arrived almost empty. The bottle seemed to be sealed so clearly a malfunction when filling.Contacted seller before Christmas but unfortunately still haven’t received a response. Poor show.

Needs a good shake before use and the bottle is massive for only 50ml.Once shaken into the tip of the bottle application is easy, looks a lot like mustard, and does stain.Once screwed together I wiped away the excess and left it to sit a while before pressuring the system again, so far no leaks from the radiator.Takes the guesswork out of using Teflon tape. Although I would imagine on removal there is a mess to clean up, same as when using normal thread lock.I also used a bit on compression joints, worked well and again no leaks at all.I think this is a great product for maybe the home DIY person who has a few radiators to fit.If you can put mustard onto a hotdog you can put this onto a fitting and get it to seal up.

Tried to install a radiator with this, left for 20 minutes each time but sprung a leak on 3 seperate occasions. In the end i used ptfe tape and absolutely no problems.Wouldnt recommend at all
