Hello to all engineers,what is your opinion with regard to using loctite 55 as thread sealant?

very good also 577

I have still not used this product,and I am curious about its ability to seal the components - parts.
Usually I prefer loxeal 55-14 with no worries at all.

Do you use it in place of ptfe tape?

 

[greekengineer]

If you watch online videos,the company suggests that loctite 55 should be used alone without any additional substance.
That is my worry,can this product offer a viable and permanent solution ?

 

[Pickwickpick]

Didn't mean whether it was used with ptfe, was wandering what context it would be used in.

 

[king of pipes]

Use it alot in place of ptfe good for cylinder fittings rad tails still get ptfe though . Kop

Really like the couple of different types of loctite I've used for various things on the bike and and on the Bedford, looks like found new use for it then!

 

[Welder]

Loved it. Far better than straight PTFE

 

[townfanjon]

Ace stuff , havnt used PTFE for years

Use it and the tape for different applications, used the liquid 577 then known simply as threadlock on metal threads but the joints must be clean and oil free for it to cure.

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

 

[ShaunCorbs]

It's the best

I have found it to be more reliable than PTFE on radiator tails especially and also more reliable on fittings in the sizes above 3/4". I'm not sure why it works better but it does in my experience!

55 does allow for some adjustment when PTFE leaks.

 

[WC1]

So you can back the fitting out a bit?

 

[gmartine]

Exactly

 

[WC1]

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

 

[DXCross]

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

[apcdave]

it's great ..... you won't regret trying this stuff... seriously the best

 

[Last Plumber]

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.
