Thanks for the video Allen! I've used Loctite 55 before (on mostly brass fittings) and was happy with the results. Haven't had a chance to use 577 yet, but it looks interesting.

I'm doing all the plumbing from scratch on a house I bought at auction. This stuff saved me. Before I was redoing connections that moved when I tightened something further up the line that jarred a connection. Since I used both of these products no leaks, and I'm using plastic and copper combos all over the place. Amazing stuff.

Hi Alan, thanks for this review. I haven’t tried either of those products but will definitely give them a try now I’ve seen your review

577 is brilliant as a refrigeration sealant. I use it on systems up to 40bar and pipes up tp 110 degrees c. Never had a leak on a thread fitting using it

Do you also apply PTFE besides 577 or do you use it on bare metal?

Hey Allen, great videos! I have a question about using liquid sealants or more to the point, what do you do if you need to re-work the fitting, say if you want to replace a rad tail. Do you need to clean the old sealant out of the internal rad threads (and if so how) or can you just apply fresh sealant to the new tail and screw it home?

Thanks for the Video, I currently use the 577 for compressed air fittings its great

Loctite has a comprehensive range of adhesives, sealants and threadlocking for use across the full range of engineering applications. You do have to use their product selector charts carefully and follow the instructions assiduously for bullet proof performance. Their technical help desk are really helpful too!👍

Thanks for the video. Ar tha from Sheffield?

Alan, I do maintenance for a group of care homes, most building are over 20 years old, the water turn off's under sinks and toilets are all brass, I hate going near them, if you even look at them there leaking, its got to the stage most times ill isolate the water in the roof space, Im going to start swapping these out what valve would you recommend..? I plan on using one with a thumb turn as it may be less prone to problems in the future.?. whats the difference between a full bore valve in comparison to normal one-there expensive-..?. What make of TMV would you recommend for this type of application, one that can be easily taken apart and cleaned once a year.. Thanks in advance.

the 55 is great stuff, never used the 577. Where I am we have codes which prevent the use of the 55 for iron pipe for gas. Its also impossible to fine, have to special order online in limited supply. But the 55 is aces when you cant get the pipes to seal up, instead of tring to wrap candle wick.

Love the way google subtitles say it can be used "sexually" at 1:36!! thanks for the video.

Hi Alan whats the curing time from applying to putting water in on a sealed system , chears.

"That goes there" isn't a great help when the camera is zoomed out so much that you can't tell what that is

can you recomend one good for the oil pan plug? i have on pan with stripped treads and i try this one 577 and dont hold strong and leak... i buy now for giv a try the hight temperature 567. If you know better please share. thanks

Bought some 577 on the basis of having seen a few videos including this one. One thing I am not totally sure on is does it work on parallel threads.? I have a couple of rads on which I need extending tails which come with parallel threads. I find that even wound fully into the rad there is a bit of movement of the tail.

Hi never used it but was thinking of using it to fit out a HWC 28mm brass fittings.Will it do it?

Allen Hart. It sets hard but can be dismantled easily, I’ve done it. In fact, it’s worth mentioning that once set, the 577 can’t be moved or the seal will break. The 55 can move easily, about a quarter turn apparently but I’ve not tried it.

I had no problems disassembling some fittings sealed with Loctite 55 a few days ago. Also as Andrew said, you can adjust the position a bit after installing. I've done that in the past for radiators in our house and had no leaks then (6 years ago). Also used this stuff on a 2" thread on a wood boiler.

So with the 577 used on rad tails how long do you have to leave it before you can subject it to water pressure? Thanks Allen. Great vids

Dušan Barlík - Seems quite common that many don’t appreciate the difference between the two, but simply treat everything as BSP. Look on Screwfix website and they are just as bad and as for Toolstation, you get nothing more than the title i.e. the tech info is simply the part number. The only way to get more info is to look at the reviews, which is crazy. Maybe i am making sweeping statements here and tarring all with the same brush, but the way it’s done seems more based on, use this compound with that joint as they’re all 1/2” and so it’ll work...and it obviously does. But as an engineer in a different discipline, i am used to having detailed technical information to-hand and not used to having to fudge stuff to get it to work.

@@AllenHart999 on their website it says that low pressure is instant, but it takes 24 hours for full pressure? I'm assuming that's mains pressure of 4+ bar?

I use LOXEAL liquid sealant class 2 (w/o numbers) too. I guess it's the same methacrylate stuff loctite uses and others , it's cheaper than loctite and works the same. Teflon +0.20mm+ tape is not working with 1" bsp straight brass fittings , every one leaked on me, a little bump or rotating force and it leaks. Loxeal holds the fittings tight, resist vibrations and it works all the time. Only drawback is that sometimes you need a huge turning force to the sealant to yeld with 1" and above, but heat is my friend ;) . Using 250mm KNIPEX pliers wrench.

I have only seen leaky yet almost impossible to unscrew connections with Loctite 55, done by plumbers who use it solely based on recommendation in the store, cause that's "the new pro stuff". Tried to redo them myself, well...done with teflon tape or paste+tow in the end. Also speaks a lot about your expertise as a plumber if you use anything else than 2 layers of teflon tape or a specialty compound dope/sealant on a platic to metal thread. Unless it was done previously with Loctite 55 - then you sure as hell need to pack it with 20+ layers of teflon, like it was metal to metal but never that Loctite crap. Or just get a new plastic fitting in that case and do it properly. I understand that there are connections where either tow or tape are inappropriate but there is still choice other than this painful rope.
