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

Fabulous product so much better and easier to use than ptfe tape highly recommended 👍

Sets firm quickly so unnecessary to tighten a joint

Great stuff but not a lot in the pot and if you’re a DIYer watch out for the pot sealing up in between uses. Be careful trying to open it back up again. Fitted a few radiators with this without any leaks. Pricey, but prevents rework.

This liquid ptfe is brilliant. I had a new radiator and new valves and just couldn't get the trv end to seal. Checked online and saw this. Read reviews and they all said how good this was. Bought it, loved it. Recommend to anybody.

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.

Really disappointed with this order. I’m sure the product itself is really good but it came in a box with other products in the same order and had leaked over them (don’t know how as the lid was on tight enough) and there’s literally like a quarter of the actual product in the bottle (as a guess, could be even less) I’m returning as this stuff ain’t exactly cheap and you get hardly anything in there? surely that’s not right?

I used it on radiator tail, valve fittings. Spreading onto the threads was easy and leaves a clean finnish.

This is one of the best plumbing products ever invented! Despite being very difficult to remove any fittings you've used this on, it has yet to fail.
