- www.intaplumb.co.uk A free lesson brought to you from Intaplumb Erith, a leading provider in plumbing, heating, gas and renewable energy qualifications. This lesson covers the basics of compression fittings, including where would be suitable to use them, and the best way to install them.
Great explanation of olives. My plumber couldn't explain why he needed one. She just said that he does, because that's how things work.
Clear and simple help - thanks. I've now fixed my leaking pipe and saved myself the cost of an emergency plumber!
When ever I need some tips for a home repair you seem to have already made an informative video about the job. Lucky me!
Just saved me an evening of stress and worry , and few hundered quid, Thank you mate
Thank you for a clear and well-informed quality tutorial.
Exactly what I needed tonight. Thank you! Never thought about putting the tape on the sleeve! Of course now I will call them olives instead! Sounds quite proper.
Professionally done video; very helpful. The only comment I have is with respect to the direction in which the PTFE tape is being applied. It should be applied in the same direction as that in which the compression nut is tightened. As presently shown, the tape would tend to unravel as you tighten the compression nut. Other than that, the video is great.
Thanks Peter, great video: clear, concise and gives the plumbingly challenged like me confidence to give it a go.

Bob on that advice for an amateur like me, brilliant, many thanks! (hope your pipework is straighter than that tie!)
Hahahahaha
Right!!! :)
Thank you for straightening your tie👔, love it.
Thanks for the clear & to the point tutorial
Many thanks for taking the time and effort to make this informative video.
That's where I'm going wrong, I've been tightening as much as I could. Brilliant thanks 😊
As long as the pipe is square into the body of the fitting and it's tightened just nice and snuggly then you don't need PTFE or any type of jointing compound. Just to let you know that this guy doesn't seem to know what he's talking about as he wound the PTFE tape onto the pipe backwards. The tape the should always be wound in the same direction that the nut tightens (clockwise) as if it's wound the wrong way round then it will just unravel as the nut is tightened. I only use tape when I am fitting new and old fittings together. If you have an old pipe with the olive embedded then it's best to tape it before fitting it to a new fitting.
@@truthseeker7794 thanks for the advice, I'm always happy to learn.
@@truthseeker7794 Old pipe with olive embedded can be tightened without tape and still be tight.
@@disastershaman Yes in the case of an embedded olive I would just wrap a few turns of PTFE around the olive and on the half inch of pipe that will be pushed into the fitting. Just to make sure, but usually I wouldn't use tape on a new fitting.
@@truthseeker7794 "he wound the PTFE tape onto the pipe backwards." Sir you are right. That, is not good, considering 900k views.
Love how his tie doesn’t follow the rules
And his shirt lol
And hammer 😂
Maybe the floor is not level, his tie is the plum Bob
😂
Thank you sir, this was very educational and helpful to me. Much appreciated!
So that's where I've been going wrong! Very clear and straightforward tutorial. Than you very much.
Thank you sir. You are a hero and saved me $140 Singapore dollars
finally a precision instructor. I looked at way too many videos that were unable to say the amount to tighten with any details besides do it right or yer a#$ out.
Nice video. These two drainage compression fittings are the last two fittings before I turn my water on. Hoping for no leaks and this info is the last info I need to complete the project. Thank you... Cheers!
Very useful! I was nervous about using compression fittings for the fact that they might leak later but I see how this would be a very effective
Thank you, that gonna help me a lot when dealing with my basement sink piping.
finally. simple. clear. thank you!
Very hepful, I had to connect my gas hose to a cooker on my boat, and they didn't send a fitting with it, so I didn't know what or how to do it. Thanks for the stern explanation.
a cool name for this channel "The Gentleman Plumber" 👍👍
Very useful and clearly explained, also the details! Finally, I understood the concept :) - thanks from worlds northernmost town, Hammerfest
I personally cringed at the Teflon tape maneuver but I’m no plumber (maritime mechanic) and we all have our tricks that we find work for us. Thank you for a good video
Yep. We all have our tricks that work! Great statement!
PTFE is tried and tested for decades. Its amazing stuff
Some plumbers use other lubricant but PTFE tape doesn't leave a residue as
Awesome video lesson! 100% correct. Thanks.
90% DON'T use ptfe tape...
Thank you for such an informative video. :) Helped me so much.
...nobody else losing their mind about the hammers turned wrong way and two files swapped to wrong positions... just me then OCD. Great explanation and demonstration though. Cheers.
i seen the hammers lol
oh, I am glad I am seeing how I fudged up this one and how it really works.
Excellent video thanks for posting
Awesome video, very useful!
Nice selection of hammers👍
Just what I needed! . Thank you
Very good video well presented
WHEN do you expect to see the return of the following items ;
1 long spirit level 😓
1 short spirit level
😓
4 various screwdrivers
😓 😓 😓 😓
1 insulated screwdriver 😓
Just a casual observation, as retired M & E contracting company C.E.O I notice these things. 😊
Thank you for saving the day! Off to fix the rad.
best tutorial of this in alll over youtube!!! good job man.. thanks
Pauljr89 559 you are joking surely pal ?
thank you. your video are so helpful.
I usually go with a half turn- get the nut on and hand tight, take a sharpie and mark the body of the fitting and mark the nut on the other side, then as you tighten you can see when the nut comes around and lines up it's done. No second guessing or wondering how much it's been turned. 1/4 turn is barely compressed at all. And lately I've added a smear of LS-X to the olive/pipe where it enters the fitting as a belt and braces for any imperfections in either the pipe or fitting....
Thank you for posting this video. I appreciate it.
thanks! I know what I need now!!! home depot waste of six trips! wow! 3 min video, priceless!
Thank-you, useful video. Pity someone people make abusive comments.
Thank you, i might get paid now!
informative tutorial!
VERY professional and helpful. Thanks!
Well done! Thank you for your excellent tutorial.
thankyou that was very helpful.
Awesome, this helped me a lot, thanks man
Really helpful, thanks for making the video.
Thank you very much!! Very helpful especially about not over tightening.
Very clear and very easy to understand, thanks very much, great help
I have been using these compression fittings for more then 20 years and tightened them as far far as I could and NEVER had a leak. (Only when I forgot to tighten them it leaked..)
Very good instruction. Thank you.
Job today.. had a 4 inch water mains pipe in a factory, it had been blocked of with a ball valve.
The ball valve blew off with the olive not leaving a mark on the copper pipe. There was ptfe tape around the olive and we removed the ptfe and fitted it all back with the bigger pipe wrench, As tight as we could. Now I'm worried because you say don't over tighten..... 😬
Great tutorial. Thanks.
Great lesson, thanks.
Nice explanation Thank You!
Found that really helpful, thank you.
This is the first video that gives an easy rule to apply how far to tighten the nut: hand tight, then a quarter turn with pliers, tighten further if there is a leak.
Good clear explanation!
That was realy useful. Many thanks.
Thanks. Well presented.
Thank you. Very much appreciated.
Thanks. Good video.
Thank you for your helpful video
Awesome 👍🏼 Now I am a TH-cam expert 🔧
thank you, very helpful, learned something :)
Very helpful, thanks
If you line up your joints properly you will never need PTFE. If they are at an angle a bit of PTFE is good to stop any seepage.
If they are at an angle, something is wrong... Ptfe tape is messing things up.. Just like using Silicone caulk when a drainage pipe is leaking.
Great advice 👍 thanks
must admit i lost track a bit wondering what tool hanging on the wall behind would be suitable to top my hubby with.
I thought that was their wallpaper
Thanks for the tutorial!
Great video and demonstration thanks very much. Would tightening it too much, not enough to cause a major leak, lead to a reduced flow rate through the pipe please?
My experience is that you can NOT tighten it too much. The leaks that come up are a result of not tighten it enough or improper alignment.
You never need to put PTFE on an olive. Just a light smear of a lubricant such as a light grease or Vaseline to allow the mating surfaces of the nut and olive to bed into each other.
Or use WD40...
PTFE is teflon based which also is a lubricant
I am just wondering if his tie is acting like a plumb line . Is he standing vertical or incline ?
Thank you, very helpful.
hello Peter, I believe that you have placed the ptfe tape on, in the wrong direction, it should be wound on in the same direction as the " capnut " goes on, otherwise it will have a tendency to unwind when you screw the " capnut " on.
your cockney accent has a very clear pronunciation of words, unlike my cockney accent, indistinctly so that the words run into one another. slurring words like a drunk.
Yep.
Good video - Thanks. The PTFE tape wrapped round the olive is a good tip as well !
Ptfe tape should NEVER be used on olives !
@@stephendunning4423 Hi Steve - hear hear! This is a real problem with many Idiot Tube videos these days - so much incorrect information put out and, unfortunately, the masses believe it!
Can i solder it as well
Thanks..really helpful
Tighten the compression nut 1/2 turn!
I tighten them till they squeak.
thanks very much very helpful
Thank you, really really helpful
Is this also usable for propane gas pipe
Excellent! Thanks
Excellent thanks
thanks much i now know exactly what i did wrong and can finish up the mess i got myself into .
I plan to custom build a modular air compression system for my shop, and I'm coming to find that compression fittings is necessary if I want to build a copper coil heat sink.
Life saver!👍🏼
@ 3.30 - shouldn't the PTFE tape be wound onto the pipe in the same direction that the NUT will be tightened - i.e. CLOCKWISE?
What about no ptfe tape, it shouldn't be on compression fittings in the first place
@@lukie4ever A professional plumber describes the procedure as "belts & braces." He stated that in all his many years of doing so, he'd never experienced a single leaky connection. For the sake of 50-75 mm of PTFE tape, it sounds worth it.
@@fontybits I'm a plumber as well and i just want to say just replace the fitting, that is a much more reliable way of doing it
@@lukie4ever Hi Lukie. Hear, hear - agreed.
Has the PTFE been wrapped the wrong way?
100%
Does that work on gas?
With water Yes using Teflon tape would be ok but not as much as in the video and apply in the CORRECT manner so when tightened the tape doesn't come loose. when on a Natural Gas application Never use tape or ptfe paste (Pipe Dope) on flared fittings.
hi frend, i want to installation of heat and cold water supply for shower and hwb so what can i do please trey to tell step by step
I was just checking around for clips which would help me consolidate some college learning. It's a good video but I'm currently half was through a two hour a week course which is run over ten weeks and know this is wrong. PTFE is not way forward but a skim of Water Hawk is right.
City and Guilds?
thank you thats brilliant
Good vid - thanks
great, thanks a lot !!!
Lo Vv .
1/4 turn on your tie would be perfect
What's the best way to remove a olive from plastic shower entry pipe, cut or pull?
Better over tighting the nut than under tighting
