- Heres how to stop leaking compression fittings the culprit normally the olive/ferrule over tightening the joint will make it worse as this will crush the pipe allowing more water to escape.

I did not think this would work. I thought this was frowned upon. I thought the tape would bind up creating bigger gaps. But this technique did work. After replacing the entire stop valve, then replacing only the ferrule, the only thing that worked was this teflon tape technique. Amazing. Thanks!
You should wind the teflon tape in the same direction that the compression nut tightens.
As mentioned in this thread That's when the tape is put onto the threads of the male portion, if it's wrapped the wrong way (ie. counter-clockwise) in that case the tape will be peeled off as the nut is closed. But the tape here was wrapped behind the olive (or compression sealing ring as they sometimes call it), there's no thread there and anyhow there shouldn't be that much tape that would catch the rear end of the nut whichever way he wrapped it.
Also, though he was turning the pipe counter-clockwise (from the olive/ring end) while keeping the spool of tape static, that's the equivalent of rotating the spool clockwise around a static pipe - which is the generally accepted 'right' way of winding the tape
I recently had a problem with leaking ferrules that were connected to a washing machine water supply valves. These were new valves, new compression fittings, and new pipes. I have used these types of fittings all of my life and I am 73 years old so I have been to the plumbing rodeo before. I took great care not to over tighten them but they both still had a very small leak. I was ready to buy push on Shark Bite valves when I saw your video. I applied the Teflon tape to the ferrule and the pipe sealant to the male threads of the valve. It worked on both valves, NO LEAKS with only moderate tightening. Thank you for making the effort to produce this video as I am an old dog that just learned a new trick. I am sure that this is a common problem that owes it root cause as being poor quality fittings that are manufactured in China to very loose quality standards.
I've worked with a lot of plumbers. Not one of them would even consider using teflon tape on a compression fitting.
That was it! I had slipped into madness! I re-taped and did not tighten much past finger tight. That was my problem. I had been tightening into madness. Thank you!
For those so critical of this video: Ever consider that a lot of valve replacement is in an older home or one where the stub from the wall is barely long enough to handle the new valve? Or that reusing the ferrule is the most practical option in some cases? Also, are you saying Teflon tape will deteriorate with age and cause failure in the future? Really??
Not every plumbing project happens under ideal conditions. Trydiy offers a practical solution and some good advice, like not over tightening.
The video is correct in what it says, but it's usually better to use a push-fit polymer fitting. They have their own special needs (who doesn't) but they are more reliable. I've had cruddy stumps of tube sticking out that will never work, but a careful clean and the push fitting sealed. Those that won't seal with a flexible O-ring will definitely not seal with a hard compression ring. When that happens the only option is to cut back to good pipe and start again. Non-demountable push fit to join some new pipe is often the best as it's much smaller diameter so won't get in the way.
A friend of mine helped me with a leaky compression fitting using this video...worked perfect...thx
Thank you very much! I wasn't sure which method to try to stop my compression fitting leak and after trying your suggestion, the leak exsist no longer!
You wrapped the PTFE tape the wrong direction, it should be applied in the same direction as the nut tightens.Just had to mention it, sorry.
Well you shouldn't put Teflon tape on a compression fitting in the first place
@@lukie4ever \you shouldn't put it on a new fitting. If it's an old one and it leaks and for some reason you don't want to replace entire fitting you will get away with PTFE. But also this guy wrapped it the wrong way. Really kills me when I see video with PTFE on a new fitting, wrap it and give it quarter turn - that's a recipe for disaster. Sometimes trusting in advice found on RUclips may end badly
That's when the tape is put onto the threads of the male portion, if it's wrapped the wrong way (ie. counter-clockwise) in that case the tape will be peeled off as the nut is closed. But the tape here was wrapped behind the olive (or compression sealing ring as they sometimes call it), there's no thread there and anyhow there shouldn't be that much tape that would catch the rear end of the nut whichever way he wrapped it.

Thank you for sharing this video. I know more about compression fittings now
"are you at your wits end?"
Yes! I was going insane from my leak! On a brand new fitting. The PTFE trick around the ferrule worked for me. Although the manufacturer's instructions explicitly say not to use PTFE tape. However I think they're referring to the threads
it usually works well but you must wind it on in the direction the nut is when tightening
@@christopherboxall46 idiot
The actual seal is where the ferrule or olive is compressed between the seat of the fitting and the pipe. That is where the application of teflon tape or of pipe dope is likely to be effective.
But the purpose of the Teflon is normally as a lubricant to allow you to tighten a fitting more than you could without it, at least when used on a tapered thread like you are supposed to. So here it is lubricating between the rotating nut and non rotating olive.
what a great presentation. you covered all scenarios
bless you my friend
Thanks ! I'm going through leaky tractor fuel fitting syndrome...... will give this a go.
you are blessing... thank you for your help sir!
If the pipe is inserted to far in the fitting it can actually not allow the compression ring to seat properly. Push pipe in all the way tighten slightly then back pipe out just a little from the fitting “Then proceed to tighten” with a little pipe compound works every time no matter the materials. A leaking one might need the pipe trimmed back a little! Tape last resort!
looked every yt video.
tanks for yor comment and wish me lock
Finally found a video on this thank you seriously
You were on 999 subscribers, so I couldn't resist subscribing. Good video too.
Great job, clear, concise, no frills, just get the job done. Thanks!
Would it be possible to apply a liquid anaerobic sealant on the outer edge of the olive. Quite similar scenario but in a espresso machine ?
the seal is made between the pipe and front of olive . shouldn't you put the ptfe tape thickest there?
Thanks I had a leak from the compression fitting/olive. I tried the PTF tape and it got it down to a trickle. I think used the PTFE sealant and knock on wood the leak is now gone. Going to wait a day until I install the toilet because its a tight fit. Thank you for the suggestions its was great in troubleshooting the issue.
Love those knipex wrench pliers!
Hi is there anyway of stopping the leak without taking it all off. Eg putting something around the edge . My pipe is old. I’m worried if I take it off I would make it worse
Definitely helped me mate thanks
Thanks!!!!
Worked great 👍
The PTFE should be wrapped so the nut doesn’t undo the tape as you tighten the nut.
But the tape is applied behind the olive/ring - no thread there. That nugget only applies when the tape is applied to the threaded portion. There's isn't so much tape that the rear of the nut will catch and unravel it.
I have always put teflon tape on compression joints, cheap insurance. But you have to wind it on in a clockwise direction, same direction as the nut you’re tightening, or it may not work. Might want to edit your video.
I thought the tape should be winded the direction of the nut tightened. I might be wrong as I’m not a professional plumber but am learning curve also the tape should be on the front part from the olive and the compound can go on the male thread for a good seal .
Noted that the Teflon tape is wrapped in the wrong direction. When the nut is tightened the tape will undo.
It seems that many have had success this way. Maybe I will try it.
There’s also old-school hemp and boss white that’ll sort out most problems when you’re running out of options!
thank you, worked great!
A bit of very fine wire wool on this old joint first and perhaps a bit less PTFE. A 1 quarter wrench turn on the hand tight nut. Then tighten up a bit more should it drip. If you over tighten and it leaks you cant undo the damage and no amount of PTFE will sort it.
Can you use a copper compression sleeve on plastic tubbing?
Never heard of using Teflon tape in this manner. I am installing two compression fit isolation valves in a crawl space so do not want them to leak especially since I will not have any access once the job is done. In just searching for some videos on installing isolation valves (SharkBite vs compression) I came across multiple instances of plumbers using Teflon tape on the ferrule. For the most part it seems to be a practice used more in the UK, but hey why not. Can't see any harm in adding this one extra layer of protection from leaks. Cheers
Bless you! Have been battling this leak thru 3 shut offs, and 2 days...
Also there is no benefit in applying jointing compound to the thread because that is not where the seal is. The threat is only there to generate the compression force.
Think I've over tightened mine and probably crushed pipe. Leaking slightly I'll leave it until next week when everyone's back at work.
I had a problem like that. I simply mixed up some JB-Weld epoxy, and epoxy-glued the copper pipe to the fitting. I first dried out the inside of the fitting so there was no water on the surfaces, and I applied a light coating of epoxy to the inside of the fitting (just a thin layer), and then applied a nice thick layer of epoxy to the pipe ahead of the compression ring (no epoxy behind the compression ring where the compression nut will eventually be). I then pushed the epoxy-coated pipe into the fitting, and then wiped off the excess epoxy with a paper towel. I then tightened up the compression nut and waited for the epoxy to harden. When I turned on the water = no more leak. Also = no way to disassemble that fitting, it is now firmly fastened together.
I like your style with the JB weld
Why would anyone use jointing paste on a thread?
Can use that on Gas in a trailer piping
Thank you sir, this fix solved the gas leak at my pilot light connection fitting.
Holy crap, I hope you're trolling
@@woodstream6137 This was my thought too.
Turn the water on. If it leaks, turn the water off, take it off and refit it. Tighten it well. This doesn't require a video
Good video, but we're you winding the tape the wrong way to the nut?
If it was on the threaded part yes on the pipe it won't make much difference because it's being forced into the gap by the nut, but in retrospect I would probably do it counter clockwise I was concentrating too much on keeping the shot in the centre of the screen 😀
@@TryDiy oh I see cheers mate.
No disrespect but you have got this wrong mate . You should never need ptfe on a compression fitting , or jointing compound for that matter . it’s actually made for threaded fittings and that’s it , but over the years plumbers have used it around the olive as a precaution against shitty cheap compression fittings that are badly made as it seals tiny areas very well. But When using compression fittings the thread has nothing to do with sealing the actual pipe it’s used to pull the olive and pipe into the bore of the fitting , so the seal is between the olive and the bore . The thread has nothing to do with it on a compression fitting so applying paste in this situation to the thread is doing nothing it has to be around the olive
@@garethrowlands1305 at least you know what you are talking about thanks cheers Gareth.
Can the copper ring be used for propane connect for fireplace? Of course different tape.
Don't you put the tape on the thread side
The annoying thing is when I isolate water supply both inside and out, water pisses out!
Take off the olive? How do you do that after it's been compressed onto the pipe?
They sell a tool for removing that without damaging pipe.
Get adjustable and hit it outwards.
Or cut it off using a hack saw
Very very carefully....

Wait a minute...the entire purpose of that ring is to seat both sides and not leak when you first tighten it by hand, give it a 1/2 extra turn, turn on the water and if it leaks, give it an extra turn until it stops leaking.
If you reopen that fitting, you have to replace that ring on the inside.
You should not need tape or dope. That is how it is designed.
Someone that understands
So if you can’t fix it with ptfe tape because the pipes been bent, you take it off and use a push fit fitting, which you can only use if the pipes not been bent???
Great advice, must get your number so I know not to call you if I have an emergency.....
YOU WOUND THE TAPE IN THE OPPOSITE DIRECTION
Where do I start...?...
It's worked for me. P.S. I had to look up "belt and braces." Hilarious!
willlewis90 “Belt & Suspenders” in regular American english. 🇺🇸
I have seen them worn...together...
Here we are again PTFE was wound in the wrong direction,a common mistake and why on earth would you apply PTFE or any other type of sealer to the threaded part of the fitting,it's the olive leaking not the threads.
What you needed to solve this leak was to toss the old misshapenned ferrule and use a new ferrule. As designed, ferrules are designed to be an one use item.
Bodge, they don’t leak if installed properly
Just use polymer push fittings. The design life is 50 years (probably longer than the copper will last) and they'll keep going long after that. They cost a bit more than cheap Chinese brass compressions but it's job done and dusted.
Nice fix thanks! Don’t worry about all the armchair DIY blokes saying ‘ooh you wound it round the wrong way it’s supposed to go round clockwise in the northern hemisphere on Tuesdays…’
That’s a diy bodge
Your putting it on wrong has to go in the direction of the thread , it’s has undone itself
It's not wrong your wrong. It won't unravel because it gets compressed. Your confused with tapping a thread
i cannot be leave the guy wrapped it the wrong way ???.
PTFE tape is for sealing threads. Use joint compound for mating surfaces.
Both work in this context and with PTFE you don't have to worry about potable water regulations.
Wrapped in the wrong direction... Good...!
Your wrong. What you said only applies to tapping a thread. Not an olive
@@christopherboxall46 you're wrong.. The nut still screws on in a clockwise direction. Taking the tape with it. Come on use your common sense.
Winding the ptfe tape in the wrong direction.
I have installed hundreds of compression fittings , there is no need to use ptfe tape, if the parts are cleaned properly, the olive will seal perfectly,
You never put the tape on behind the olive. In front and on the olive. Embarrassing
Wow... clearly not understanding how a compression fitting works
Sometimes you pull off the old compression fitting with the tool and there is not enough space left to make a cut on the pipe. Had to use this method to seal a new toilet shutoff valve. Wish the compression nut didn't leak after I removed the old one but don't have the money to pay a plumber to come out and extend the brass pipe. This will have to do.
@@brianc9036 ooof, thats rough.
Thread tape wrong direction and I'm an electrician 🙄
Teflon tape lol
Tape the wrong direction !!!
it don't matter because it wasn't taped on the threads
I’m not a professional plumber 👨🔧 👩🔧 but really...truly speaking; when connecting compression fittings; you shouldn’t have to use special plumbing tape or compound solution. When fitting the Olive onto the copper pipe....there is a knack to it; when tightening the compression nut. But personally i much prefer using push fit...fittings.
I’m supposed to be refitting my kitchen out; but not being a professional plumber.....I’ve got this awful feeling that it’s not going to be finished this year anytime soon😞☹️😒

You are embarrassing yourself. Teflon is a lubricant for MIP pipe threads. That tape will kink and cause leaks this will cause more troubles than help.
Mark Harmon I don’t agree , where did you read that in a book
@@heatservicebwcuk1545 I am sorry. I have noticed that many others have had success with this technique. Many of the failures I have encountered were due to sloppy use of Teflon tape on compression fitting threads. The tape somitimes laps onto the olive causing a discontinuity.
Mark Harmon ptfe tape around the thread does nothing to help the seal. A couple of wraps around the olive is harmless , however , jointing compound is always my preferred option.
Thanks
BWC
You're talking bollox
You are right Mark. The only thing I use on the ring before tightening the nut is a little pipe dope.
Why not just do it right 🤦
If you don't know what you are doing don't try to teach others. This comment is from a real plumber
