Loctite 55

[rocketmanbkk]

I used this for the first time yesterday on a compression that wouldn't seal.

Spot on

Excellent

I've got some, never used it though. You have to rough up the threads with your pump pliers first according to the instructions, never fancied doing that.

 

[rocketmanbkk]

Really, I don't do that!

Never heard that one, never had a problem myself. (Not saying your wrong mind).

I think it says you should rough up the thread but I never have and haven't had any problems. Its good stuff.

 

[rocketmanbkk]

Just slapped it on bit, it really does bite.

I had a rad tail extension a couple of weeks ago that was an absolute bugger to seal, I considered the loctite, but ended up with 22 (yes 22!) wraps of PTFE, I went up in 5s from my usual 12 wraps until it held.
I think the thread roughing is to hold the loctite and stop it sliding out as you tighten the fitting. Will have a looksee at the loctite site, I'm sure there's a video.

No video, but it's right there on the website, step one - do the unthinkable to yoru fitting mg_smile:

22 I usually put 18 on as standard and I had one batch of cheap reads & valves that all leaked until I put between 36 & 45 wraps, used about 10 rolls of ptfe on that job

Do you mean a male or female iron rocket and your putting the 55 on screwed fittings, if its just a compression fitting i wouldnt be putting loctite 55 on anything.

My starting point is normally 18-20 wraps aswell if i ever use PTFE

 

[Scott_D]

I find one wrap / gas ptfe is much better
Locktite 55 is good, I rough up bigger threads with a hacksaw blade

 

[rpm]

I used to carefully place the 55 cord in the threads not wrap it like a birds nest as shown in that video.

 

[Ch4 plumbing]

Used loads of 55, never roughed up the thread and never had a problem.

Mind you I use it exclusively on LCS not rad tails ect

 

[plumbdoctor]

Any of you used the liquid stuff I nearly passed out when they told me how much it was ! Never brought it.

 

[rpm]

Never used it myself.

 

[ShaunCorbs]

577 plumb ? If so its good very good

 

[Chalked]

It is expensive. But very good for difficult jobs when you need yo line a fitting up.
I use it for making valves onto chrome towel rails. Put a small amount on the start of the thread and screw in hand tight. Leave for a couple of hours and that's it! I tend to do them the day before. So far no problems.

Shaun beat me to it Loctite 577 on everything threaded I have used it since they made it is very good also better than the previous 572

I've hit the liquid too but never used it.

I like RPM just put it on the thread. Worked a treat.

I didn't have a choice. I just wouldn't seal. It was either loctite or ptfe or an adjustable through the window!

I would argue (not me normaly) Loctite 577 is faultless

Never have a couple of hours to wait so tape or cord for me then.

If its just compression get a decent tub of jointing compound for the future.

I'm fascinated by how good this 577 stuff is but as rpm just said I can't really think of a use for it. I use PTFE on everything and have no issues. If something leaks with ptfe it needs redoing not trying something else.

No don't do with pump pliers ... You will need a normal hacksaw blade and scratch the thread so the it gets rough to get a better hold.

Loctite is best stuff , you do not need much and it seals perfectly

You can use it for anything no everything it's good for steel and brass threads ... Good for gas pipes

 

[Roger Welton]

577 is great, just a bit pricey, and the small pots don't last long.

 

[SafeGasInstall]

excellent gear that , i don't use ptfe anymore
