Something I've noticed when picking out parts and supplies in stores was a lack of proper instructions, so this demonstration was very helpful to me. Thank you.
Seems to be quite a few 'experts' here who say it shouldn't be used as a sealant ...... whilst they may be technical experts, the reality is that it works as a bloody good aid to sealing a joint, so in the real world I'll carry on using it. Great vid mate :- )
Wow…you posted this video 14 years ago. Well…it is still really helpful!! However, I wished I watched it before using PTFE - as I made every mistake in the book and have some minor leaking to a bottom entrytoilet outlet valve. On a bright note I get to do more practice - this time using the correct method. 😊❤
Thank you! I can cook anything but this was new territory for me in my 17 yr-old RV. Had to replace a rubber washer in a brass fitting then re-assemble it with new PTFE.
excellent video demonstration . Unfortunately there are as many 'experts' out there as there are radiator valves that have nothing better to do than critisise others . The correct amount of PTFE tape to apply on a fitting is the amount needed to adequately seal the joint . There is no 'magic' number of turns. If more than 6-8 turns of PTFE tape is needed to seal then there is something wrong with either the radiator tapping or the radiator valve tail thread or both.
@ultimatehandyman Thanks for the video but I have a further two questions please. How many times do you wrap the tape around the thread? Secondly, if the thread was wider, would you wrap a width of tape across the whole thread or just the end of the thread and would you warp it around the whole thread multiple times? thanks
I normally do between 10-15 rotations. I have installed thousands of metres of threaded pipe from ½” to 2” and never had a single leak (water/compressed air/condensate). A few months back I helped a mate install two fancy radiators at his son’s house. I put the tails in one side and he did the other side, I did my normal 10 wraps minimum, he did much less! At that point I was thinking that perhaps I use too much PTFE tape, until the water was restored and his tails leaked and needed redoing 👍
Would this work the same fore a toilet inlet valve? The end of the valve is facing towards the floor, if i eas looking up at it what way would i wrap the tape? Thanks
I have been a plumber for almost 30 years and no longer use PTFE tape now. Have you tried loctite 577 and loctite 55 , Much better than PTFE tape. Good video 👍
I have some of the Loctite, as it was recommended in a RUclips comment, some time back. I have not had chance to try it yet, but will do when I get chance. Can I ask why you prefer it over PTFE tape? Thanks for the comment
Although you say PTFE is not needed on compression joints I am considering using it in future. The olives on modern joints seem to be a much harder alloy than the old ones were, and the joints leak when tightened normally. I got over that by substituting good old fashioned olives, but have run out of them now. Without them, I find joints have to be tightened to the point where I feared stripping the threads before they become water tight. I am about to install a bathroom suite using isolating valves and flexibles. My dilemma is, should I try to temper the olives by heating to red hot with my blowlamp and plunging in water, or should just wrap them in PTFE tape?
I found this video useful, to fix a thread in my floor lamp stand to stop it moving. Nothing wrong with your accent Im from yorkshire which is the most trusted accent. Im guessing yours in Lancashire way on.
Been looking at most of your videos on here and their the best ive seen and well demonstrated!!. Top job. People wanna learn some manners, Prentencious a***hole. :) keep them coming.
Thanks. These basic techniques are the things we don't get taught, yet we kinda bluff our way through and bugger it up and get a leak!!! Thank you thank you thank you. More please. Subscribing now.
This may be a dumb question, but.. I am installing the spout on a bathtub. I have a piece of 7" pipe with one end going into the wall and the other going into the spout threads. Does it matter if I install the pipe into the wall first, then screw on the spout, or attach the 7" pipe to the spout first, then screw the whole assembly into the wall? I want to get the spout to end up in the right position, facing down for pouring the water. Thanks.
+Barry Schwam I'm not entirely sure what you intend doing, but as long as you screw the threaded parts in tight they should be fine. What you can't do is try and install a piece of threaded pipe that is threaded on both ends into a gap because as you tighten one end up the other end unscrews. I hope this helps ;-)
I know this is 2+ years old, so hopefully you've finished installing your shower arm by now, but I thought I would answer for others! To install your shower arm, first wrap the PTFE tape around the threads 5 or 6 times just like this video. I would leave the first thread on the very end exposed so it's easier to start the connection and you don't get tape into the pipe. I would not connect the shower head onto the arm yet. Next, screw the shower arm into the female thread inside the wall. You should go 4 turns if you can. If you get to 3 1/2 turns and the arm is sticking in the wrong direction, you can stick the rubber coated grip of your channellock pliers into the shower head end of the arm as leverage to complete the final turn and get the arm properly facing downward (one reason for not attaching the shower head to the arm first). Now you can attach the shower head to the arm. Use a wash cloth or something between your pliers and shower head so you don't risk scratching the finish.
Many thanks .. I think I'm now brave enough to fit an isolation valve to my shattof shower which has chosen the day before Xmas eve to catastrophically fail..
No, threadlocker is no good for leaks as far as I am aware. You can get some thread sealing paste which can be used on water/compressed air but I prefer the tape.
No, it would not hurt it- bit it is not necessary, unless the olive is damaged. Compression fittings work by compressing the olive into the fitting and it gripping the pipe, making a water tight seal, hence it's not really necessary on compression fittings. These videos might explain it a bit better- ruclips.net/video/KOxZE4zL6rE/видео.html ruclips.net/video/6PR0zTU_v30/видео.html Thanks for the comment ;-)
Should it be one continuous piece? I have a galvanized water pipe; I'm putting a new angle valve on it. It's about 2 inches from the bottom of the cabinet under my sink. It's very hard to get to, and the tape gets pulled together into one or two threads of the pipe. I found that if I cut 5 pieces or so, I can get it wrapped around the threads. Would rather do it in one continuous piece like you show unwinding it from the spool..
Yod12 No, it does not need to be in a continuous piece, as long as you get at least 1 3/4 of a wrap or more from each piece. You might be better off using some liquid PTFE if you can get some?
When i was a kid i can remember asking my dad who used to be an electrician what PTFE stood for?. He said "Plastic Tape For Engineers" probably because Teflon Polytetrafluoroethylene is a bit of a mouthful or he didn't actually know. But it sounds good and that's what i tell people when they wonder what it means.
A lot of people think it's called plastic tape for engineers 😂 I can't even pronounce words that begin with the letter H, never mind polytetrathingymebob Thanks for the comment 👍
@xXxchipperchopperxXx Depends. I just had one that needed around 8 - less than that, and it leaked. I hope it doesn't decide to leak anyway when I'm not home :)
Hi, what about putting the tape on a tap that is on a sink and you have to struggle to get underneath. How do you put it on correctly in this situation. Could you do a video showing that please. Or on any pipe that is close to a wall. Cheers
Hi, you don't need to use PTFE tape when connecting taps as the tap connector will have a washer in it to create the seal. You would normally only use PTFE tape on threaded components, such as the radiator tail in this demonstration. If you ever do need to use it near a wall etc. it is much more difficult to use and is easier to use if you apply a couple of lengths of the tape- but it's difficult keeping the tape straight and it often turns into string in such situations.
Hi, I have a heat meter (siemens wfq407) that leaks at the threaded joint. Every once a year the rubber gasket fails. Should I put ptfe as an extra? The water is 60 degrees celsious.
i got this with my mic arm and i wonderd what it was never seen it before in my life then i quickly relised what it was for as the screw part for connecting the mic to the arm was about 2mm to small so i searched how to use thread tape and your video came up
I am going to put teflon tape on the instant water heater output connection to the shower hose. How many rounds (turnings) of teflon tape should I put? Thank you
That was educational. Thanks. However, I would have liked to see you actually screwing something, plus you said it could unwind if you do it the wrong way - it would have been better if could demonstrate these things instead of merely talking about them. Because at the end of the day demonstration is usually 100 times more effective than words. Hence, generally your videos are great. Also maybe demonstrate what happens if you have too many/few revolutions?
Minor point. Your meant to leave a few threads clear at the end to stop PTFE getting in to the pipe. Doesn't matter in domestic water but PTFE flying round an industrial system isn't good.
I've spoken to a couple of plumbers how many times to wrap ptfe tape around a radiator valve and both have told me about 20 to 25 times but in the videos thay only say about 7 or 8 turns so the right and the wrong way can you put to much ptfe tape on
Just got a bidet that came with this stuff. I didn’t know what it was so I didn’t use it. No leaks so I’m good mate. Edit: this man still replying to comments after 9 years
Some teflon tapes are really thin compared to others. With the thick tape two rounds would be enough. I not know the specs on different tapes but there is a real noticeable difference in quality
I find 3-5 times is sufficient for most jobs. Less than 3 and I've seen fittings leak. And as Vishwan said, if you keep the tape off of the first thread it's easier to get the pieces to thread together.
when doing my basin taps i cant reach up from underneath and get the tape around the thread properly, even applying the tape first then dropping the tape threw the hole makes no difference because i still have to tighten the tap which then compresses the tape on the thread before i connect the flexi hose, what a shit.
Need help please. I went around 10 times with the PTFE tape on the threads but its still leaking from the threads. shell I go around more ? like 15 times or so.
Normally they have a rubber seal, but sometimes the seal breaks or is damaged. If the U bend is leaking from the joint, you can use this tape to seal the joint, I have done it a few times myself in the past. Thanks for the comment 👍
Problem with this tape is, when you screw it on, you go clockwise. But, when applying to a radiator and you screwed it on to far AND want to reposition it a little bit back, counterclockwise, only just a little bit, it's going to leak. When you really want to position things like this one, you better use hemp.
it depends also on the quality of the tape you use, if you a really cheap cheap tape which commonly is a very thin film it will let leaks easily, a good quality tape is kind of thick and i will not let a leak happen so easily, also sometimes i use this same technique as he explained it but just like two or three turns clockwise and later on top of that one and a half counter clockwise turn, the idea is the counter clockwise turn kind of unrolls a bit the tape inside and make a tighter fit
I would say that six is the minimum. I’d do between 6 and 10 wraps to be sure. I was on a job with a mate a few weeks back, I installed two radiator tails and he installed the other two. He had to go back to the job, as his two tails were leaking! 👍
It has been my experience to always use both. Use Teflon tape 3-5 wraps and pipe dope over that. I know this is 2 years after you asked, but this has been the best method I learned working for a plumber and doing maintenance for over 10 years.
Absolutely. But of course, there are some people on here that think that two turns are enough 😂 I always put plenty on, especially with compressed air or steam- I have never had a leak yet! Thanks for the comment 👍
+Sheri Southam Sometimes you have to remove a length of the tape from the roll and wrap it around the threads the best you can. Don't worry about it twisting as it will still create a seal.
Хобби
Always apply the tape clock-wise when the end of the pipe is facing you.
Richard Stevens lol that simple i just always thinking to make it good
Unless your fitting has reverse thread.
Something I've noticed when picking out parts and supplies in stores was a lack of proper instructions, so this demonstration was very helpful to me. Thank you.

This is the first video I have seen that actually shows the correct method. Well done.
First time home buyer and a female.... thanks easy to understand and worked well!
Glad it helped
Thanks for the comment
Tip... try not to get ptfe on the first thread... it makes it easier to start coupling up.
Thanks for the comment ;-)
Ooh. Nice!
first thread from the shank or the loose end? which end?
The tip end where you will screw in. From the video, the right end.
Thank you good Sir!
Thanks !!I managed to fix my tap with your help.

yes correct but you really dont need that much just on or two wraps and its good
Nice reminder thank you !

think its sorted. i used a newer tail i had from another valve. seems a bit deaper. and this one has a rubber seal for the valve
Glad you have sorted it ;-)
Ok lasted longer then normal but still doing it after 15 rounds . Only slight. Doing my head in now

Yes, it's worth a try ;-)
thanks!
Good point about it being wound the correct way so it doesn't undo when screwing into the hole.
Thanks for the comment
You only need 2 to 3 windings on NPT thread, it's tapered so no need for so many windings
hoogmolen lol i counted 7. im a newbie and just did one.
Ya after he did more than 3 turns I cringed
Except all fittings in the UK are straight cut BSP threads. We don't use NPT. You need more than 3 to get a good seal on BSP.
@@98dizzard not all... there is plenty of tapered fitting used.
It also depends on the condition of the fitting.

Can ptfe tape be used with garden hose connectors (the click-in-place ones)?
Yes, but it might not do much. Normally if they leak, it's because the O ring is worn or perished 👍
Can you use PTFE tape on a leaky pipe that's dripping?
If it's leaking from a compression fitting, or threaded joint you can. But if it's just a hole in a pipe, PTFE will not work on it's own.
Mission complete, liked and subd👍👍👍
Thanks for the comment and sub 👍
how many times around do you wind it...
+Teina Toru
I normally wind it around about 4-5 times minimum.
Thanks for the comment
That guy did it 6 times and a half. So a bit more than neccessary.
3 is enough.
Some teflon tapes are really thin compared to others. With the thick tape two rounds would be enough. I not know the specs on different tapes but there is a real noticeable difference in quality
I find 3-5 times is sufficient for most jobs. Less than 3 and I've seen fittings leak. And as Vishwan said, if you keep the tape off of the first thread it's easier to get the pieces to thread together.

You don’t need ptfe tape on taps, as they are a parallel thread. The sealing washer will seal it.

Need help please.
I went around 10 times with the PTFE tape on the threads but its still leaking from the threads.
shell I go around more ? like 15 times or so.
Ten times should be enough to be honest, but trying more will not cause any harm.
Navneet Murti
u need help because u use that tape...it's total bullshit.. use the floss string or flax
Gam eR thanks mate its been sorted now
Navneet Murti ...Nice...don't use that BS. i work as a plumber in SWE...nobody sane uses that and for good reasons :)
damn should have watched this before i applied the PTFE tape... cant remember which way i did it!
If it's tight it will be fine, putting it on the right way just prevents it from coming unwound when tightening the component.
Can/should
can/should this be used for a plastic u bend?
Normally they have a rubber seal, but sometimes the seal breaks or is damaged.
If the U bend is leaking from the joint, you can use this tape to seal the joint, I have done it a few times myself in the past.
Thanks for the comment 👍
Problem with this tape is, when you screw it on, you go clockwise. But, when applying to a radiator and you screwed it on to far AND want to reposition it a little bit back, counterclockwise, only just a little bit, it's going to leak. When you really want to position things like this one, you better use hemp.
It's for a radiator tail, there should be no need to go counter clockwise- you just apply the tape and tighten it up as much as required.
it depends also on the quality of the tape you use, if you a really cheap cheap tape which commonly is a very thin film it will let leaks easily, a good quality tape is kind of thick and i will not let a leak happen so easily, also sometimes i use this same technique as he explained it but just like two or three turns clockwise and later on top of that one and a half counter clockwise turn, the idea is the counter clockwise turn kind of unrolls a bit the tape inside and make a tighter fit
also if you want things perfectly positioned, then you could go with a high temperature and pressure thread sealant
You mention no need PTFE on a Compression Joint at 0.32. What is a compression joint?

You went around 6 times. Is that your average? or do you recommend more or less depending on the material.
I would say that six is the minimum. I’d do between 6 and 10 wraps to be sure. I was on a job with a mate a few weeks back, I installed two radiator tails and he installed the other two. He had to go back to the job, as his two tails were leaking! 👍

***** Hey Chez, can you show me how to do this with PTFE cord?
Never used it to be honest. I have only ever used PTFE tape, I have never used the cord or the liquid PTFE sorry.
Can I use pipe-dope instead ?

It has been my experience to always use both. Use Teflon tape 3-5 wraps and pipe dope over that. I know this is 2 years after you asked, but this has been the best method I learned working for a plumber and doing maintenance for over 10 years.
How much should you use? Twice as much as you think! I do 16 turns on a rad tail.
Absolutely. But of course, there are some people on here that think that two turns are enough 😂
I always put plenty on, especially with compressed air or steam- I have never had a leak yet!
Thanks for the comment 👍
Very helpful thanks.
Correct way of wrapping
👍
Very helpful - but how do you apply it to pipes that are fixed to the wall, without the tape twisting?

Sometimes you have to remove a length of the tape from the roll and wrap it around the threads the best you can.
Don't worry about it twisting as it will still create a seal.
+Ultimate Handyman Thanks :-)

Who gives this video a thumbs down? And seriously folks. IF THIS HELPED YOU GIVE IT A THUMBS UP!!! It’s free and takes less than a second!
Haters gonna hate ;-)
Thanks for the comment
better if you use the whole roll?
no
Should have stated which direction to apply the tape. My guess is to follow the thread as stated below
If you hold the item in your left hand and apply the tape, like I did- the taps is always the correct way ;-)
Will this handle High heat without melting ?
PTFE tape can normally cope with temperatures up to about 250 degrees Celsius.
Thanks for the comment 👍
Are both sides of teflon tape same?
Yes, they are both the same ;-)
