Leaking Compression Tube / When to Use Plastic Ferrules

[@donjohnson3701]

The factory polyethylene supply tubing to my ice maker was leaking . The hardware guy told me to use the copper ferrule! I later learned that I needed a plastic ferrule with a copper insert. After installing, it still leaked. After putting my glasses on I learned that the plastic ferrule isn’t like the copper ferrule. It has a flat side and a tapered side. The flat side goes toward the nut and the taper goes toward the fitting. Tighten only a quarter turn-no need to crank down on it! ( they call the copper ferrule an “olive” across the pond). So to make a long story short, thanks for the great video .

Thanks Bob! The plastic ferrule recommendation saved my sanity. I had to replace a section of 3/8" plastic tubing for our reverse osmosis system under the kitchen sink. The compression fitting still leaked after 3 attempts with a metal ferrule. The 4th attempt with a plastic ferrule worked perfectly... no leaks, no further adjustment needed. I should have consulted KZbin and you at the start!

Came here because I was installing an undersink water filter that came with PEX tubing and a Metal Ferrule I tried so hard to get the ferrule onto the PEX tubing to no avail... wondering why they would have either an improper sized ferrule or just an incredibly difficult task After seeing how easy it was to slide the ferrule on in your demonstration - It's clear they: 1) gave me a metal instead of plastic ferrule 2) gave me a furrule that is much too small Thank you for clearing up my mental fog and providing me with a solution!

Can't thank you enough! Purchased an icemaker kit, contained plastic tubing with brass nuts and a metal feral inside the nut. After tightening and turning on water, it leaked like a sieve. Never would have thought of plastic ferals... thank you again!

[@pauloutdrz]

Heard an Australian guy call the ferrule an "olive". I've seen metal ferrules used with PEX HOWEVER they use an insert at the end of the PEX to make it stiffer. Similar to the plastic insert in Sharkbite or similar fittings that should remain in place when using PEX (and can be taken out if using copper).

[@jamesbinns8528]

That was exactly what I needed, and could not find anywhere else!

[@crazyleesonic]

Hey Bob, Great video, it told me what I needed to know within the first six seconds, but I stayed and watched the rest of it. I was nearly going to use a brass ferulle instead of the plastic one today. I replaced a sink in my house, and the distance between the faucet and spigot was about 22". I couldn't find any braided hoses longer than 20", and so went with the PEX. Here's an interesting plumbing story that might make you laugh. I moved to the US from the UK about 20 years ago. My first trip to Lowe's or Home Depot, I went in there and asked for a hose to connect to my stopcock. They were like "you can't use language like that in her Sir". I said "no, the things that go to the tap". "You need a tap?" they replied, "try the tool isle, we have tap and die sets there". After learning that I needed to ask for spigot and faucet, the language barrier was overcome, and I was on my way. Thanks again.

Thank you so much!!! I just installed a new dishwasher and I had a pex-type water supply line with an existing metal ferrell. Well, the long and shorrt of it was that even with the new dishwasher that came with a metal ferrell it leaked immediately!!! I will go and get some of the plastic ferrells today so hopefully fix the leaking issue so that my wife can run the dishwasher.

[@E3ECO]

Thanks! This showed me a couple of things I needed to know today: what orientation the ferrule should be in and how a plain tube fits into the connection.

[@BobsPlumbingVideos]

The tapered portion of the ferrule faces the valve or fitting. the nut sits over the flat portion of the ferrule.

[@charliecharlie9377]

I just had a massive blowout because I installed the ferrule flipped the wrong way. I tested and monitored the connection for many days without any drips or problems whatsoever. Then, one night when we were all asleep in the house it catastrophically failed. Thousands of dollars in damage that I probably won’t be repairing. My beautiful new hickory cabinets ruined. It’s amazing how much water can come from a 3/8” opening in just a few hours. Water down the street! Guys! This is from a semi-professional that made this mistake. I knew about the plastic ferrules and not to use metal on PEX. I just forgot which way to flip the ferrule. Hating myself so much for this.

[@E3ECO]

@@charliecharlie9377 Ouch. My condolences.

[@idmhead0160]

@@charliecharlie9377 Sorry to hear it. I really don't trust these connectors at all. I had what could have been a catastrophic event like yours a day ago. Only, luckily, it happened when I was standing right there. I was using the sprayer in the sink. The sprayer has a weight on the hose underneath the sink that pulls the hose down when you are done with it. I think maybe the weight hit the plastic tubing going to the dishwasher. I heard a massive spraying sound. Luckily, I figured out what it was pretty quickly and was able to turn off the shutoff valve within about a minute. You are right, 3/8" leak is like a fire hose. I wonder if they make a PEX crimp fitting for 3/8"? I've used crimp rings on 1/2" and 3/4" PEX and I trust that a lot more than I trust this.

My swamp cooler has been leaking for months...a guy from a reputable hvac company came out twice and it was still leaking...and a knowledgeable home depot employee told me what the problem was...a plastic tube needs a plastic ferral and don't use irritation tubing just because it fits..it may not handle the pressure...using the right parts makes all the difference.

Recently bought a house and the nylon supply tube absolutely sucks. Had my bathroom sink leaked at both hot and cold connections. Water started leaking through the roof on the bottom floor. Had to replaced them with the new stainless steel braided tubes from the store. The solid chrome plated supplied tubes on any of my other sinks are still solid after 20 years (previous owner installed them in the 90s).

The pex supplies we used to use didn’t come with plastic ferrules but we kept them on the truck. That’s all we use to use. Now the supply house don’t even carry them. We use flex connectors. I’ve had to go to Home Depot to get plastic ferrules. Though I believe on 1/2” pex and up you can use a brass ferrule

After watching this I went to the local hardware store to get my plastic ferrule replacement, asked one of the employees where they were and he tried to convince me to get a brass one, saying “I JUST re did my sink plumbing too and I used a brass one, that’s what you want to use on plastic and everything.” And I tried to gently explain what I’ve learned from you, and he was like “nope, brass is fine, trust me” and I was like “nah, I think I’m still gonna go with the plastic on plastic” but inside I thought… someday you’ll get a leak and remember this conversation haha. Thanks again for sharing your knowledge, Otherwise I know I would have been easily swayed! I found my plastic one, installed it, and by tomorrow we should officially have running water in our new campervan home! Thanks Bob!

Awesome video!! Very enlightening. Our plumber likes the copper and pec and hates the other two. With the copper pipe, do you have to replace it if it has to be replaced, because the ferrule becomes squashed.

[@BobsPlumbingVideos]

You can remove the damaged ferrule and replace it with new.

[@jonalarcon8564]

Thanks Bob you answered what i was wondering if using the metal Farrule on plastic pipe. I guess plastic to plastic metal to metal

[@JackJensenTrader]

Wonderful. I used copper ferrule on p.e.x. and it didn't (to my knowledge) damage it, but it didn't seal, despite cranking down a ton. I can't explain that, but after going back and buying both, then seeing this, I tried the plastic and about 3/4 turn past snug (I was going to keep upping it if it leaked after testing) and it was leak-free. It tried several turns with the copper and it was still spraying.

[@mr.tactown.253]

I know I'm late to the party but I had a question for you, have you tried doing only 1 complete rotation when using the metal ferrule on the plastic pipe/tube? Also, was the kind you used PEX? Because I heard PEX was really the only suitable/kind of plastic pipe/tubing that can be used with a metal ferrule. People also usually over tighten those rings as well which is another problem.

[@mr.tactown.253]

Just asking because when you mentioned using the metal ferrule, you said you were cranking down a ton and then trying again by doing several rotations, which could have been the problem, another thing that comes to mind is those little long metal pipe/tube/fitting that come included with compression fittings/adapters which are used to put inside plastic pipe to keep it from bending or something.

[@JackJensenTrader]

@@mr.tactown.253 I actually don't recall, but I'm almost certain that I didn't do the "cranking down a ton" at first. Only after it failed to seal. I should take notes on what projects I've done, because I seem to forget about them fairly quickly, including this one.

[@mr.tactown.253]

@@JackJensenTrader It's alright but yeah I guess maybe it could have been the missing insert that goes into the PEX pipe to keep it from bending/deforming.

[@1mw4tch1ng]

I just replaced one of my toilet 90 deg water valve the other day and decided just to replace the valve body and re-use the nut and brass compression washer/ferrule (would be hard to remove). I bought my house new all pipings is PEX tubing throughout and the plumber who installed the valves used brass ferrule that came with the valve. It's all about saving money for the plumber contractor and would cost a little more by using the correct plastic ferrule on my PEX piping, it's a one-shot installation, and does not care if the home owner will have to deal with the brass ferrule later.

[@BobsPlumbingVideos]

Dear Bob: I am reading from a BrassCraft Multi-Turn Angle valve # 27 OCR19X R1 instructions and it says "if using PEX Pipe 1- On 3/8" OD and Smaller, use plastic compression ring. 2- On larger than 3/8" OD, use brass compression ring with stainless steel tube insert. 3- To install, hand tighten, then add an additional 1-1/2 to 2-1/2 turns with a wrench". Dear Bob have you tried to use this method? have you run into trouble using it? I would like to know your opinion. I notice that most of the fittings you get new from the store are damaged. The contact fittings with the ferrule have scratches, burrs and nicks and they cause licks no matter how tight they are. I solve the problem by taping the fittings with "valve compound grinding" to make them smooth and able to make perfect contact around the fittings.

[@BobsPlumbingVideos]

My experience is with 1/4" & 3/8" sizes for witch I'll use the plastic ferrules sometimes w/ or without the brass inserts. On larger sizes I've seen guys use Teflon tape with pipe joint compound to get it to stop. Torque until the water stops. try not to over tighten if at all possible.

[@SteveRivett]

How about plastic/rubber tubing used a ferules on copper? I'm swapping an old 8" spread faucet to a new vanity and that is what I found on the little copper tubes between the spout and tap handles. The old ferrules have fallen apart so I need to figure out what to replace them with.

[@BobsPlumbingVideos]

Most modern widespread faucets have plastic tubing with pre installed plastic ferrels. They also provide a couple of extra plastic ferrules in case you decide to cut the tubing shorter. So my answer would be to use the plastic ones.

[@paullandry8301]

Very well explained - thank you. I will try to fix the leak

[@whatfreedom7]

The shut off valves come with the metal compression fitting so most people would just use what’s there not knowing any better. I bought the same pex line and mine didn’t come with anything. Now I need to go buy all the additional parts I need. Is the tapered end on the large end just a compression fitting? Would you just use a nut?

[@BobsPlumbingVideos]

The end that connects to faucet takes a brass nut and act as a compression fitting.

I've done all kinds of handy man plumbing on my own homes, but have always used copper or the hard plastic. Now I'm installing a water filter with flexible poly tubing while using copper ferrells; complete nightmare (water filter system came with no hardware or instructions, just the shell). I decided to go with the poly tubing and the sharkbite connectors, but they either didn't have the right size fittings at the local HD, or I had to go into a copper valve. Either way had to use some compression fittings with copper ferrells, which took a while to get them to stop leaking. Heading back to HD to change them out for plastic.

Hello Bob. I'm not a plumber. Just some schmuck who is forced to do his own home repairs for financial reasons. So forgive me for any critical comments or slight additions to your instructions here. But it seems to me that you omitted a few important details in places. One, is that when joining a line of any sort, whether to a valve, such as a shutoff valve, or to another fitting, or section of pipe, etc., one should make sure to insert the pipe in as far in as possible until it stops. If it is not in far enough, that too can create a leak further on down the road. This is true for all types of connections, I believe, whether made by sweating pipes, or gluing pipes, or whatever. Also, those plastic ferrules you showed us. You've probably noticed that, unlike with the metal ferrules, the plastic ones are not symmetrical. They sort of taper down from one side to the other. The fatter side is meant to go toward the nut, and the slimmer side, toward the main piece, such as the shutoff valve, or whatever. These are small concerns, I will admit. But the products are designed that way for a reason, so best we follow the rules, no? Again, not trying to sharp-shoot you: but only help out. Please correct me if I'm wrong on any of these comments, and most of all, keep up the good work, Bob. Anyone who makes videos to help the general public should be commended for adding some good to the world, which is in dire need of such kindness. So thank you, my friend.

Short of purchasing an expensive ferrule removal tool you can use a very fine hacksaw blade 32 teeth per inch. Make a cut diagonally straight down but DO NOT go all the way!!! Score it so you can get a thin blade screwdriver and split the ferrule open without damaging the pipe. I've not seen plastic ferrules in either 1/2" or 3/4" sizes and if the pipe is schedule 40 P.V.C. the metal ferrule should not damage the pipe.

The instructions that come with the Delta faucets suck. The diagram in the instructions does not represent the supply lines. The plastic ferrules are associated the extendable handheld line. The bag the plastic ferrules comes in shows a diagram of the line going to the angle stops. Thank you for such a clear and informative video. I've been a plumber since 78. Experience is very valuable. I used the factory termination on the supply lines. I was left wondering what the plastic ferrules were used for. Oftentimes when you use plastic ferrules there are brass inserts that go inside the tubes.

Hi. My wife's toilet was leaking so I decided to replace the old line with a stainless steel one, along with a Brasscraft 1/2in Nom compression 3/8 1/4 turn valve with a stainless steel line. Few days later, I find a small, small leak. Removed everything, and thought, okay, so I should use the old nut and compression ring, so I ordered a Superior Tool Olive puller and was about to start, until I stumbled upon your video. Seems the homeowners prior to us (maybe even builder) placed a brass ferrule on the PVC line. How or what would you suggest the route for removal, and from there replace with a "Polyethylene Compression Ring"? Thanks.

I simply use a very fine tooth hacksaw blade 32 teeth per inch or a Lenox mini hack saw (google) and cut across the ferrule until almost thru. (not completely thru). Then with a very fine blade screwdriver placed where you were cutting, split the ferrule. You don’t want to score the supply tube. If you cut it, you’ll have no choice but to replace the supply.

great great educational videos for plumbing newbies like myself. keep it up.

Thank You, Hanan. Glad to be of assistance. Regards, Bob.

I work in an apartment complex and every angle stop in every unit has metal ferrules on pex pipe but they have an insert in the copper, I'm new to this profession as was wondering why they did this and do those inserts help with the ferrule cutting into the pex?

[@BobsPlumbingVideos]

I've personally never seen "inserts" that would prevent the metal ferrule from cutting into the p.e.x. at least not here in N.Y.C.

[@gloiban]

BobsPlumbingVideos thanks Bob

[@adamross1878]

I think the inserts he is talking about are stiffeners. They keep the end of the pex from bending, but don't stop a metal ferrule from cutting into the supply.

[@Dactylonian]

What about the brass insert? Is that not needed? Context is plastic tubing, plastic ferrule, and brass nut.

[@BobsPlumbingVideos]

it is needed, still would not use a brass ferrule on a plastic supply. Only plastic!

[@790Lexx]

Larry Stapleton 0 seconds ago Bob, do you need a brass insert into the PEX tubing for the plastic ferrule to anvil and press down onto the PEX?

[@BobsPlumbingVideos]

You’re supposed to use the brass insert with the plastic ferrule, although I’ve left it out more than one time.

[@crazyasjxion3340]

👍Thanks great information Bob! Had a small hole on my pex and just need to replace it.

[@BobsPlumbingVideos]

You're welcome and thanks for checking out my video! Happy Plumbing, Bob.

One of the best instructional videos I've ever seen. I've got 1/4" polyetheylene for an RO system. It requires using it with a compression fitting. I definitely understand the plastic ferrule, what about the "insert" for the tube? My kit was supposed to come with a plastic insert but didn't. My local hardware store has only brass inserts? Can I use a brass insert and a plastic ferrule, with a polyethylene flexible line?

[@BobsPlumbingVideos]

Absolutely, you can use it. Most kit are supplied with the brass version. Thanks for checking out the video! Regards, Bob.

Excellent video!!!

I have a chrome supply line at the toilet. I loosened the nut that has the furrel in it now its leaking after I tighten it. It wasn't leaking before. Any ideas how to stop it? Thanks

[@BobsPlumbingVideos]

You may want to wrap some teflon tape over and around the ferrule one or two turns, then try to tighten. If that doesn't work, I would cut the ferrule off with a very fine (32 teeth per inch) metal mini saw blade and use a brand new ferrule.

[@fancy8365]

What do I use if new faucets lines do not reach the water supply cut off? It came with the metal braided tubing.

[@BobsPlumbingVideos]

These will extend you an additional 12" -12" Braided Stainless Steel Hose Faucet Supply Connector (3/8" x 3/8" Compression) - amzn.to/3dBmQs9. Remove and disregard the nut and ferrule from one end, connect to the lines coming from the faucet. Connect the other end to the supply valve. They come longer (20") as well.

[@jman24961]

Can I use the same valve that came with a metal ferrule and substitute a plastic one or do I need a special valve that accepts the plastic ferrule?

[@BobsPlumbingVideos]

You can use the same valve, just substitute a plastic ferrule.

Hello, I have 1/4" grey pex risers for the bathroom faucets. I changed the fixtures a year ago and reused the pex but had to bend it some. Now I'm a bit concerned and considering replacing with SS braided supplies. The pex is likely 15 yrs old. Also had an unrelated frozen pipe burst so have some extra "hydro phobia".... You think it's okay to bend the Grey risers? Hoping the original installers used plastic ferrules for the connection to the shutoff too. Thanks for your great videos!

[@BobsPlumbingVideos]

You can certainly put mild bends in p.e.x. without any issues. Even at 15 years it shouldn't be an issue, but for piece of mind new stainless steel risers can't hurt. Nothing is safe from freezing. Thanks for checking out the video! Regards, Bob.

[@justtisha]

For the rigid bullnose supply lines, what size nut do you need? Or can you use multiple sizes? A toilet had the 7/8" but faucets have the 1/2" connection and the stores only sell one side of the bullnose supply lines. And what sort of fitting do you need the bullnose to fit into? I'm thinking I might want to have a riser terminate into a half inch copper but I don't know what fitting to use for the copper. Do you use any washers with the bullnose before you put on the nut?

[@BobsPlumbingVideos]

Not sure of the term "bullnose supply line" can you send a photo. Send to - [e-mail].

[@justtisha]

@@BobsPlumbingVideos it must be a local term. It's the same as the chrome plated copper line you had in your hand. The little tag at home Depot said bullnose but online it says "faucet riser with compression sleeve"

[@bartholomewdelaronde3712]

what do i do if its leaking from the orange gasket on the solid tube? can that be replaced?

[@mikemccarver2734]

Bob, which was does the plastic ferrule go? Does the tapered end go towards the fitting? Your video showed both ways. Also, what about the little insert that goes inside the plastic tube to keep it from collapsing from the compression?

[@BobsPlumbingVideos]

The brass insert goes inside the tube you're connecting, the tapered end of the ferrule faces toward the fitting you're connecting to.

[@iamdave84]

Oh, that's what that insert is for?! I'm on here looking for a video on hooking up ¼" tubing for a fridge and I think my shut off valve has one of those.

[@comesthru]

Mose hot cold bidets come with a 6 ft long hot water hose. Is there any way to shorten it? a 6 ft hose takes far too much space under the sink.

[@BobsPlumbingVideos]

Braided hoses?

[@bradkilgore3088]

How to remove brass ferrule? Great video, not sure if you monitor this any more but I have 1/2” pex supply line for toilet leaking. It has a brass ferrule, that I cannot remove. I purchased a ferrule puller that screws on, but the adapter will not fit inside the pex, it has a metal insert. Any suggestions on how I can remove do I can replace with a new plastic ferrule?

[@BobsPlumbingVideos]

I just use a mini hack saw by Lennox or a 32 teeth per inch hack saw blade. Cut at approx 45 degree angle thru the ferrule, but stop before hitting the pex. Use a thin blade screw driver and pry the ferrule open. Replace with a plastic ferrule. If you’re not to sure on how to go about it, I would just use a new braided stainless steel supply tube and be done with it.

[@bradkilgore3088]

BobsPlumbingVideos thanks very much for replying. This is coming out of the wall so I cannot easily replace. I will try cutting it off and get a plastic ferrule. Thanks again

[@melissanative1799]

@@BobsPlumbingVideos Wouldn't you still need to remove the tube before replacing it with steel tube?

[@digitalsnot]

10:32 - that’s the info i’m looking for. i don’t know why delta can’t spell this out as clear as you did. their directions for shortening their pex is joke. thanks a bunch

[@tac73]

Don't you need a brass compression insert for plastic/PEX tubing?

[@BobsPlumbingVideos]

The correct answer is "yes". Use them if you have them!

[@6thDAY]

Just wondering, when do you want/not want to use a brass insert and just a plastic ferrule instead, for plastic tubing?

[@BobsPlumbingVideos]

I generally use the brass insert on plastic 1/4" ice maker supply lines, but truth be told for ice makers I prefer 1/4" copper tubing . For sink supply lines I'll use the plastic ferrule alone..

[@handyman7635]

With all the earthquakes lately..... Get rid of solid pipe connections. Steel braided and pex is best in my opinion. Hard pipe is tough! But one quick shake.... Major damage.

[@BobsPlumbingVideos]

Good point for my California friends👍

[@Guyhakverdi]

Great video Bob! Could you also make a video about fittings that are used in Pex floor radiant heating systems?

[@BobsPlumbingVideos]

On the production list! Thanks for asking Guy, regards. Bob.

[@PankajAhirwar]

Where can I buy plastic ferrule, I cannot find in any big box store or online ?

[@707SonomaComa]

Would you recommend a chrome plated copper supply line over the stainless steel supply line for a toilet? What would the advantage be? I live in California and there a earth quakes here. Would flexible be a better choice? The stainless steel lines look real bad over time because you cannot clean them.

[@BobsPlumbingVideos]

For earthquake purposes I guess the braided stainless steel makes sense!

[@jessicabarton3852]

It is my understanding that the plastic ferrule, when properly tightened should just slightly crease the outer diameter of the pex tubing. This is what ensures the pex supply line doesn't pop out of the nut on the valve connection...Is this correct?

[@BobsPlumbingVideos]

That is correct, but if you use the brass ferrule and overtighten it, it will penetrate the pex. Thanks for checking out the video Jessica, Much appreciated, Bob.

[@mikefennema5561]

My favorite is the PEX risers. They are inexpensive and I have never had one leak. When I replace a faucet or toilet ball cock I always repace the PEX. I tighten the nuts between one and 1-1/4 turn after finger tight.

[@594bolt]

I just installed braided supply lines and now the water has a rubber taste to it. Going back to poly.

[@omlettedufromage8588]

found this while replicating a fuel line... 1/4 steel tubing with a brass compression ring swaged at the very end... what is the crimping tool called for this?

[@BobsPlumbingVideos]

I watch plumberparts.co.uk and see that he also calls them olives! I haven't seen copper ones here in the states only brass and they have a tendency to cut into the p.e.x. Thanks for checking out the video.Regards, Bob.

[@somethingelse4878]

In the UK its a compression olive ;-) I have just DIY fit a electric shower 230v 8.5kw uk and the last shower had a copper olive, the manual says use a olive But the shower inlet pipe is plastic what do I do? Also the old plastic inlet pipe has a stuck olive should I cut it or pull it off I don't want to crack it or scratch it The shower inlet is plastic not the 15mm water inlet pipe that's copper with chrome

[@BobsPlumbingVideos]

In my opinion, if it’s plastic I would use a plastic ferrule. I just wouldn’t want to chance cutting into the plastic with a brass ferrule.
