Tried both today on a 3/4" T piece for the dishwasher tap. PFE kept leaking a drop occasionally (even with 7 windings) but Loctite worked perfect. Is more expensive but certainly worth it.
Best demo of how to use locktite 55 out there well done great demo
Thanks very much
That Bahco spanner is luxurious. I feel like a king whenever I use that same one.
Finally, someone who understands ptfe tape! I've never used loctite 55. I am very excited to learn!
55 is great stuff, give it a go
As a non-professional who has used PTFE tape for decades I concur: loctite 55 is absolutely phenomenal stuff and I won't use anything else for the rest of my life. Can't recommend it highly enough.
When I was an apprentice ptfe was as thick as one wrap which is used for gas. Over the years it’s gradually got so thin it’s practically useless.
Its almost like you cannot fail with loctite. Even if you do it less accurate or precise it will still work. Once in my life I had a leaking connection done with loctite, just a few drops... I was tired, I decided to redo it the next day, I put a bowl underneath the connection and went to sleep. Guess what: I sometimes still check this connection at home, but did not fix anything and the connection never leaked again (was made 4 years ago).
Thanks for your tips that I installed my garden faucet back properly. Before that it was at 30degrees and dripping.
Thanks for the tip to use Loctite 55....it made may day!
Glad to help
Very helpful video. Was getting very frustrated with tap fitting beforehand. Cheers.
Glad it helped
Great demonstration
Yer arms are gorgous m8!
The video certainly helped me out! The service guy at the DIY store didnt knew what product would allow you to adjust the connection a little.
So intuitively i bought locktite 55 (the brand is amazing) and thanks to your video i now know i have the propper stuff for the job :)
Thanks and good luck with the rest of the content.
Grtz. A Dutchy
Thanks 👍
I never knew much about the thread type.Both have their benefits on different applications. I'll be needing Locktite 55 for an outside tap.
👍
Clearly explained.
7 turns of a .075mm PTFE tape is about half a mm, which is absolutely not enough.
Been in the irrigation industry long enough to realize you're best reading the product specs of what you want to thread, in my case, on swing joints with tapered threads it specifies 1mm of material to be added to the thread, which is about 14 turns.
You don't put enough, the tape thins out and disappears, you put too much and you'll end up turning the entire tape when tightening the fitting.
Thank you for this.
Your welcome
Thanks a lot, really helped me! very clear instructions!
Your welcome 👍
great demo thanks.
Glad you found it useful
Great explanation thank you I’ll go get some chord.. What a coincidence though -I’m just doing my shower now and the very part I need is the bit you’re threading into the wall plate, what’s it called!!? My wall plate is too recessed into the wall..
Just used Loctite55 for the first time. It's the Dogs' B....... I'll be using that for threads in the future.
It is indeed 😄
Hi. Would you use the Loctite 55 for a fixed wall assembly? Up until now I have been using a combination of Hemp covered by PRFE that created a perfect seal. Moving to Loctite seams very modern, but the last thing I want is the joints to start dripping and than having to open the wall to stop the leaks.
Yes I would. However if I were you I would practice and gain confidence in the product on an accessible fitting first
Dont waste your time with PTFE. I tried at least 20 times on 1/2 thread. Then i bought Loctite 55 and it sealed perfectly from the first time!
Interesting. I am a pump technician and use thread tape or hemp & soap. I was working with some contractors and they swore by sealant cord. However, when I asked them to explain why it’s better. They didn’t know besides just saying “its better”. Good informative video. I might keep a couple of rolls in my vehicle. The biggest issue for me with thread tape is lining things up. If you have to back off a BSP thread. It often drips. I tighten everything 99%. Put everything in position and then rotate all the fittings that last 1% to line it all up.
👍 thanks for sharing
@@TheDIYGuy1 Bro do not do this, it's nice to see you replying when you have something to say but just having a generic thanks for leaving a comment is a really bad idea.
Thanks a lot I'll try to use 7 turns of PTFE I put way too much on it (around 12-15 turns)
Yeah that's a bit too much.
Loctite 55 all day long
Great video,
Thank you!
nice one, thanks.
Anytime 👍
I think we should leave the initial turn or so of the threads without tape; to avoid difficulty getting started.
Thanks for your views
if PTFE is started on thread correctly not an issue.we had same with Bosswhite and Hemp many moons ago
@@tomobrien8417 Sometimes an insane amount of PTFE tape is required now; e.g. 20 turns for radiator tails for the cheap radiators that are common now. With that many turns it becomes a problem. Next time I am going to try using ptfe paste ("pipe dope") at the same time. Bosswhite & hemp is probably better, I wouldn't be surprised.
Great video. Would you use Loctite 55 on radiator tails? How many turns would you do? Thanks!
Sure would 🙂
Locktite all day. Used on PVC swimming pool pipe connections solved lots of irritating problems, especially peristaltic chemical injection valves...
Do you think there's a minimum thread size for the 55? I've used it on 3/8" threads but i think it's tougher to apply on them compared to 1" for example.
No I think it maybe more fiddly but it should do the same job.
@@TheDIYGuy1 I find the Loctite 577 paste better on the small BSP threads like 3/8", 1/4" and 1/8" to be honest 😳
@@smitbar11 or LOCTITE 542 on fine threads works a treat
If you want the fitting apart in the future you might not mange it as Loctite 55 has a setting compound which is great for sealing leaks but not so good for splitting later.
After I watched this, and I used the 55, finally there is zero leak at the 'T' junction where I just connected the water supply for the fridge. (ice maker) :)
It really is great stuff
i always do 13 turns with PTFE on rad valves amd garden taps... Any less feels too loose. No leaks sine 2001.
Fair, everyone has their own little methods 👍
I wonder if I can just twist up some thread tape to get a similar effect as the thread? I will definitely try that. I've never seen it on sale here but would buy some in a heartbeat since it seems great for very large fittings, especially above 1" (probably sucks on tiny fittings like 1/8 though).
Not really because the Loctite is polyamide and not ptfe.
@@VladoT Huh, should have guessed it was a bit more special. Kinda sounds like it's ptfe coated nylon thread, so I could just wind ptfe tape onto dental floss right?
jk, I'll find some actual stuff lol :)
55 for me every time except as you say on an old olive where PTFE is the best
Thanks for your comments
Which one is better for air compressors for an air tight seal please ?
Loctite 55 or a liquid thread sealant if it's not likely to need undoing again.
Does the 55 for pcp air Rifles with 4500psi 300bar tanks ect 🤔
If its is a permanent fixture use 577 or 542.
I hate the way bsp fittings have to be sealed with ptfe. I've done radiators and pneumatic systems. It's often a frustrating process that doesn't seems to tighten until you have he whole roll on. Will be trying this loctite 55
Give it a go, it's great on bsp
55 is far superior. We stopped using ptfe ages ago at work because of leaks and ptfe isn’t any good on bigger pipes. When on the rebuild after the Flixborough disaster in 1978 our company installed about a mile of 4” compressed air using ptfe and it leaked everywhere. The whole lot had to be stripped again and revealed with BOSS White and hemp.
Is the Loctite 55 just PTFE but in a cord format? Could you mimic Loctite 55 by just twisting some PTFE tape instead of lying it nice and flat?
No this is a different product
Will it work on 300 psi car clutch threads...? Clutch hose....
Not really. Should be copper washers or tapered fittings. If it leaks you need to polish the sealing surfaces.
Can you use this tape on internal drinking water taps.
Yes you can.
@@TheDIYGuy1 sorry to be a pain is ok to use items like la-co slic-tite compound and wicks potable jointing compound on the same.
it's impossible to work with PTFE, today I had to install a bathroom sink at home, which needed two 1/2 inch valves, it didn't work at all with PTFE, it kept dripped down the side, even though I wrapped it 7 and even 12 times. After 7 revolutions, you can simply screw in the valve with your hand, no tools are needed, so it's bad, 7 times is really too little, and I used thicker, more expensive PTFE... it's good that I had linen at home, it worked with flax from the first time, there was no water leakage.
This looks good but won't work the way I wrap my joints. I put the pipe in, slide the olive to the joint then wrap the lot in PTFE, thread and olive and pipe. Then the nut goes over the whole kaboosh and seals everything in - can't do it with thin string 🤷♂️
You dont use ptfe tape or loctite if your using an olive. That is what the olive is for, to seal the connection.
@@tommygrimes7921 That's what everybody says online, and all fine in theory, but if you've ever tried to refit an old compression joint or fit a new joint to an old thread you'll know that it can be no end of trouble trying to get the fitting watertight. A few turns of teflon over the olive is so much better than finding a slow drip under a cupboard 2 days later.
You don't use string for olives. He says it's not suitable in the video.
I don't understand what you are doing with your compression fittings. The way they work is they compress the olive on to the pipe, that seals the olive to the pipe and the olive seals to the fitting. The thread and the nut are not part of the seal (they just mechanically press the olive into the fitting).
If it leaks and they often do because the olives are poor quaility or on an old fitting that you've disturbed then you wrap the olive with PTFE overlapping the pipe on the fitting side and then you assemble it. You don't need any PTFE on the nut side at all and none on the threads as it is not part of the seal. If you don't have any PTFE between the olive and the fitting then you haven't fixed the point where they leak and you are relying on a seal with the nut on the threads and the back of the olive neither of which is designed to be water tight.
When you have PTFE between the olive and the fitting it doesn't get shredded as you do it up as the two parts don't rotate as you do them up so it is less likely to leak.
I dont know about bpt but 7 turn us way to much on npt
Does this product have an expiration date? I have had this product for 3 years and I don't know if it has expired or not.
I don't believe it has an expiration date
first time i saw the 55 a rep was demonstrating it and he said it it was important to rough the threads a little with grips or a file before use it says on the instructions also
The Loctite leaflet suggests you only need to roughen up the threads on chrome & stainless steel fittings.
@@vegn_brit5176 99 % of radiators tails are chrome and need roughening i just think its needs mentioning and again i spoke to loctite and they agree
A plumber told me it was necessary to file the threads on brass fitting as well. This prevents the PFTE String/tape from slipping.
55 is made of hemp?
It's good stuff
I am very happy with both, do not use 55 for glycol, carefully read instructions for other fluids!
Buy blue monster ptfe tape. Do 4 wraps and you will never have a leak.
I've really wanted to like loctite 55 but shit just leaks.
Don't use loctite 55 on solar installations. It breaks down and leaks but it's good for dom h and c water.
Ptfe tape is crap. Will definitely try to locktite. The fact that you can position your connection better is perfect.
Loctite is great stuff
Or hemp an plumbers mait
👍
You shouldn’t use Loctite 55 or ordinary ptfe on Oxygen pipe. Loctite 55 is very good unless you want to split it in the future because it has a setting compound in it.
👍
Take off the Butchers Apron on your arm
👍
Random/Negligent way of wrapping, a big NO. The random wrapping is wrong. The first wrap should not cross the screw threads at all and the direction is against the rotation. Then, if possible, another run, or as many as needed to obtain a little and CONSTANT opposition while rotating. If in the video that negligent wrapping works, it is simply luck. Do not play gambles with gas or water.
u talk too much
😂👍
