Always been straight ptfe but often wondered about the loctite. Any one say why it might be better than ptfe on some application ? Thanks. Wc1

55 does allow for some adjustment when PTFE leaks.

So you can back the fitting out a bit?

 

[gmartine]

Exactly

Great, I'll give it a go. If I'm gonna try something that could cause a leak in a customers house, I need to know why I should try it. Thanks

Definitely +1 for loctite. The newer shaped containers with finger imprints are a god send.

I use it all the time and have stopped buying PTFE tape as much because this does a better job.

I use Flomasta Pipe Thread Sealant from Screwfix on outside taps to wallplate elbow connections. It's the next best thing to welding it on, it's that strong. Using this on the threads eliminates the need to line up the wall plate elbow with the tap using a wrench as it can be turned to whatever angle you want and left for an hour to set. It won't move again and is fully watertight. When replacing outside taps, I usually replace the wall plate elbow as well so the fact that the tap can't be removed isn't a problem. To use it, I coat the threads of the tap with a zig zag line all the way round with the Flomasta and apply a ring inside the wall plate elbow. Screw both of them together to whatever angle you require, wipe off the excess and sit both on a kitchen towel for an hour. It won't come apart again.

After having used loctite 55 , I must report that this product gives the impression of a perfect sealing.
The tip is that you must cross - crossing the tape on the thread.
I ended up on the loctite 55 after having failures with the use of ptfe. Especially when I used ptfe on short adds on (photo below) or parts with short thread.
I noticed that loctite 55 offers a better solution .

Ain’t used PTFE for years - normally scratch up the thread a bit to give it a bit of adhesion, another vote for loctite 55!

What do you mean by scratch up? As in like keying in with some wire wool/wet&dry/emery or something else? Have never used loctite 55 but think will give it a try after all the recommendations in this thread.

See the vid in my earlier post, loctite recommend keying quality metal threads when using 55

First got loctite 55 for dual fuel t-piece / element, which have a nasty habit of ending up in the wrong orientation otherwise. Now I use it for all rad tails, outside tap, shower outlet... etc It’s much better than ptfe!
