LOCTITE 577 HOW TO USE
Unlike the loctite 55 this can only be used on metal so ok only metal fittings the 55 can be used on plastic to metal or metal to metal so the 577 is only for metal ok so this will give you a lock as well as a seal for any fitting that you want to lock its very good so if you did something like an outside tap you could move it to the correct position if you need to get the alignment correct its also very good for that very good little accordion pack that's not the one i want to use this is the one i want to use pull the nozzle up and use the little pump applicator so its very easy to apply so you saw how easy that is but its a quick product and it stays put as well so if you apply it to a fitting its not going to run around the fitting and drip on the carpet or drip onto fresh grout so to apply you apply a little bead to the leading edge of the male thread now for that size thread that's enough bring the two together and as you wind the two together you will see how it pulls the product all the way around ok so now you do it up so with threads like that we are trying to fill up all the gaps this product which is a liquid plastic and when you get metal contact it turns to a hard plastic so you do that up and get it to where you want it and then you can get your pipe grips and do it up or just leave it like that to cure ok so you have taken the air away and the metal contact that will now cure so anything that's left outside the joint just wipe off and it leaves you with a really neat finish around the joint so if its on a modern shower fitting or a stainless steel radiator or a designer radiator and you don't want to see the pipe sealing cord you can use this and it will leave you a very nice neat fitting so 577 hot water cold water potable water it will do lpg it will do gas you will need to leave it to cure before you can pressurised system Loctite 577 how to use and apply

[@bramhagyani5018]

Can it be used for 1"BSP plug for 300bar WP hydraulic system with VG46 oil & 60 deg C temperature?

[@covinhas87]

I've been to an lpg shop to buy some fittings to do my lpg application, also I ask the guy for some sealant for the threads and he sold me some loctite 242. I was in a rush, didn't question the guy but now I'm afraid as I never heard about 242 for sealing. Is it safe to use 242 for lpg fittings or I must use 577???

[@kdir8727]

been using this ever since on motorcycle fuel quick connectors thread, one side aluminuim otherside Nikkel Brass, and lives in Fuel !

Pek çok soruyu yanıtladığımdan emin değilim. Mümkün olduğunda tercüme etmeye çalışıyorum. İzlediğiniz için teşekkürler

[@Razz60]

Allen can use this 577 on the thread of imersion heater on the heating element thread?

[@ArksE8]

The liquid ptfe from screwfix is really good aswell. Costs £6

[@ubcnme1]

Can Loctite be used on for example the pipe fitting is stainless steel and the female side is aluminum can it be used..

[@saraweshwaranbashkaran4499]

Can I use this for air conditioner flare fitting?

[@WaschyNumber1]

Does it work for hpa 4500psi 300bar air applications? 🤔

[@leeedwards3783]

Has anyone used this on potable water and hot and cold? I have been told it is only suitable for potable water upto 23c if used with an activator?

[@alekhyakonisi4916]

How much it is required for curing after applying loctite 577

[@1966human]

Ah yes but will it stand up to fuel as in fittings to a mechanical fuel pump

[@joefowler9600]

Hi Allen, i fitted a towel rad and valves a few months ago, that my client bought online (cheap)😫 Continuously getting a drip from the tails, ive tried ptfe wraps right upto 20 wraps, ive tried loctite 55 again multiple times with no luck. Ive now changed the tails, but started to drip again, i really dont want to have to change the radiator. Im thinking about trying loctite 577, but worried that it wont seal and i wont be able to dismantle the tail afterwards. Have you ever had to remove a tail after 577 has been used and just how good is 577 at filling out the thread? Thanks

[@AllenHart999]

I have never had 55 leak on any fitting tbh so i am not sure. Maybe the rad is cracked?

[@losteden]

good product but dont work with oil, i use it in oil pan plug and leaked, i buy now the hight temp 567 and is good

[@learnprogress6618]

Hi , so I can use the 577 on the Concealed grohe grohtherm Thermostatic Valve for the shower 🧼 and bury that in the bathroom wall and be sure their is no leak as long as both connections are metal ?

[@josephkurian5419]

Where available this one

[@davefordham14]

So how long does Locktite 577 take to cure? In other words, before letting air or gas into the pipes after sealing and tightening, how long do you wait. Seems like a very important question which wasn't answered in the video. Anyway, I think to be on the safe side I'll leave it 24 hours plus. That should do it.

[@igorchuchro4991]

did you get to know ?

[@trifiananto2021]

About 2-3 days

[@andrewportess8434]

1hr per 1bar pressure

[@ballababy00023]

you get an instant seal for moderate pressures.

[@mikauzer2926]

It says it's slow curing at low temperatures? Could you confirm what they regard as low temperature? Many thanks.

[@AllenHart999]

No idea. I have never had one leak yet though. Thanks.

[@mikauzer2926]

Did some digging, thought I'd let you know. It's range is -55 / +150c

[@AllenHart999]

@@mikauzer2926 Thanks.

[@markstricklands]

Anyone know if this works for air? I've got a air bag system in a truck suspension that Teflon tape isn't sealing, just wondering if this might be the fix?

[@billroach2393]

I'm about to use this stuff in an air application too....max 150psi. How did you end up getting on with your truck suspension please?

[@KSTURNIP]

Hi Allen. Can I use this Loctite 577 for 6 Inch diameter, SS-304 Pipe and Fitting?

[@AllenHart999]

Not sure you would need to double check with manufacturers. Sorry.

[@KSTURNIP]

@@AllenHart999 Thanks a lot for your kind attention.

[@alinawafali6228]

I used for two inch copper threaded fitting it's work

[@D.Mulder]

I used this stuff on my waterpump fittings (the brass fittings) for my irrigation system. The weird thing is, it didn't cured. I can still turn the fittings by hand. The other weird thing is....it doesn't leak. How long does it take to dry out complete? Or should it not get hard like glue?

[@AllenHart999]

The metal to metal bit will dry. The bit on the outside just needs cleaning off. Thanks.

[@D.Mulder]

@@AllenHart999 Thanks,, i did that today on a few couplings. It worked for those, i will check my other fittings soon.

[@AlabamaTree]

I used some 577 on an LPG threaded fitting yesterday. I came back to it today and the excess sealant outside of the thread is still as it came out of the tube.... is this correct?

[@AllenHart999]

Yes you wipe it off,

[@AlabamaTree]

Allen Hart - Thanks, I’ve wiped it off now but I was expecting it to cure, but I guess it’s only in the threads that it cures.

[@oddhelgeb8560]

He applys only partial onmele treads. instructions sais both mail and female treads 360 to be applyed !??

[@jerryz673]

Hi Sir, can I use it with the loctite 55 together?

[@mohdzainuddinsenin5792]

Hi. Is the pipe need to be dry off first before applying 577?

[@AllenHart999]

Yes

[@zm23f]

Dry and oil-free.

[@borisapantelic7186]

How long does it take to cure?

[@AllenHart999]

I normally leave it at least 10/15 mins before I fill the system up. 👍

[@Hussain-ch3pr]

Can fittings be undone later on?

[@AllenHart999]

No.Well maybe, Not easy though

[@lensen639]

If you heat it up, its no problem.

[@kristianvendramin]

Loxeal 58-11 is better

[@AllenHart999]

Why do you say that ? Thanks.
