PTFE Tape or Loctite 55 | How to use PTFE tape and Loctite 55

I am very happy with both, do not use 55 for glycol, carefully read instructions for other fluids!

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).

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!

That Bahco spanner is luxurious. I feel like a king whenever I use that same one.

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.

Don't use loctite 55 on solar installations. It breaks down and leaks but it's good for dom h and c water.

i always do 13 turns with PTFE on rad valves amd garden taps... Any less feels too loose. No leaks sine 2001.

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.

Very helpful video. Was getting very frustrated with tap fitting beforehand. Cheers.

I've really wanted to like loctite 55 but shit just leaks.

Which one is better for air compressors for an air tight seal please ?

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

Thanks for the tip to use Loctite 55....it made may day!

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.

Loctite 55 all day long
Great video,

Will it work on 300 psi car clutch threads...? Clutch hose....

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.

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.

55 is made of hemp?

Ptfe tape is crap. Will definitely try to locktite. The fact that you can position your connection better is perfect.

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?

Great video. Would you use Loctite 55 on radiator tails? How many turns would you do? Thanks!

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

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.

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.

Thanks a lot I'll try to use 7 turns of PTFE I put way too much on it (around 12-15 turns)

nice one, thanks.

Finally, someone who understands ptfe tape! I've never used loctite 55. I am very excited to learn!

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) :)

I dont know about bpt but 7 turn us way to much on npt

Can you use this tape on internal drinking water taps.

Thanks a lot, really helped me! very clear instructions!

Just used Loctite55 for the first time. It's the Dogs' B....... I'll be using that for threads in the future.

Unde ai invatat meserie?

Or hemp an plumbers mait

55 for me every time except as you say on an old olive where PTFE is the best

great demo thanks.

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 🤷‍♂️

Best demo of how to use locktite 55 out there well done great demo

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.

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

Does the 55 for pcp air Rifles with 4500psi 300bar tanks ect 🤔

Thank you for this.

I think we should leave the initial turn or so of the threads without tape; to avoid difficulty getting started.
