Good video. However, a brass connector to compression on a copper pipe works good. Brass to a plastic tubing works ok, but you must use a metal insert into the plastic tubing. Without that support, it will always leak. I would also attach the copper tubing to the wall and also the plastic tubing. If these are not held down, someone could tear them off by accident.

For polyethylene tubing, use polyethylene ferrule. Don't use brass (a.k.a. olive), it will cut into the poly tubing- brass is for copper tubing. Also, no plumbers tape on threads. (a mistake I've made). -When using those push together things: if/when it does leak, take it apart and re-cut the end of the tube with a proper tubing cutter, don't re-insert without cutting off that 14 inch of buggered up tubing. Also, when using compression fittings on poly, the brass sleeves are important to keep the poly tubing from collapsing. It looks like the sleeve is integrated into the barbed adaptors. Thanks again!

The compression water fittings assembled dry will tend to leak, assembled with a teflon pipe dope or even a wrap of teflon tape will help prevent leaks

Teflon (or PTFE as we call it in UK) seems to work quite well when it comes to sealing the olive (ferrule, cone etc). I presume by pipe dope you mean joining compound?

basically i'd do the exact opposite you've done. those push-fit fittings are made for plastic tubes. they will eventually fail on metal tubes since they can't grip as well on them.. The compression fittings never leak, unless you install them like a plumber that thinks more torque is more betterer. crushing them is what makes them leak almost everytime. screwed to contact then a light snug is all that's needed with these but everyone insists on cranking them to hell then wonder why they piss water everywhere :p

I was having such a hard time installing the traditional brass fittings to connect the two lines together. I was going to buy more of the same, but asked if they had what you are recommending and they did. It was so simple to install. I can't believe how much time I tried with the old way. Thank you! I did overpay for it at Ace at about $6.99 for one and the link that I just now clicked on that you provide gives you a 10 pack for $6.99. I might have to just buy the pack to have them on hand. Thanks this was very helpful!

Thanks for posting the video. It was a headache for myself until I learned when connecting to poly tubing we must have a insert in the pipe to prevent leaks so the compression fitting, ferrule can really clamp down strong.

Tons of value on every single videos, thank you

OMG, I have been trying to figure out a problem I have adding drip irrigation to my Tower Garden. I just happened across your channel and found the answer in this Podcast. LOL What is the most amazing is you live in my home town!! Go figure... Thank you very much for your channel, I am now subscribed.

The the plastic one you pointed to was leaking because it was done wrong. You can't use compression fittings on plastic tube without the copper inserts that go inside to stabilize them!

Cheap plastic push on connectors do leak over time especially when they are outside. Barbed fittings reduce the ID of the tubing, but they work. Brass ferrule fittings work great. On cooper the tube needs to be clean and you should use a little vegetable oil on the ferrule. It also helps to anneal the copper a bit with a propane torch and let it cool naturally. On the plastic part just use vegetable oil and only finger tight plus about a half turn, then turn on the water and tighten until it stops dripping if it’s dripping at all. Ferrule fittings work just fine and do not deteriorate like plastic in the weather. They been around forever. I absolutely do not trust cheap push to connect fittings for water in a home. If that fitting breaks that 1/4” line could do a lot of water damage.

Good video ! Yea, totally agree on the brass coupling they seem to leak after a period of time. Also agree on the poly fitting. I have used them for 10 years now & they do work well. No leaks so far on a water filter job using poly fittings after 10 years. Was there a couple days ago & still doing well.

Problem with compression fittings on plastic pipe is people tend to give them the same amount of torque as they would when doing up a joint on copper pipe work. Compression fittings can be used on plastic pipe no problem, but you need to nip them up enough so that it the olive doesn’t grip the pipe properly or gets squashed into the plastic itself. Generally speaking, compression fittings should be done up with a bit of PTFE tape (Teflon as you guys call it) around the olive or smear on some jointing compound as doing them up dry can be risky.

Cool. Thanks.

New video idea - am I the first person to ever think abt opening some ductwork in my attic to get some cold air in the attic when it is 130 deg in my attic? Is there an open / close fitting that I could install in my ductwork to temp push a/c into my attic when I need it?

GASP!!!!! Right up front he didn't debur the inside of the 1/4" -pipe- TUBE after cutting it..... again, *GASP!* 👍😁👍🤣 All joking aside, I like these connectors and I'll have to order some, but the right size for our under counter filter. I like keeping stuff in my kit. Because, we all know full well, leaks always start, Sunday mornings at !:27 AM. True story. 👍😁👍

Would you make a video about heat pumps?

I've been trying to figure out what I want to do with this mobile home that has copper water lines, bottom is 3/8 in and the top goes into a 1/2 in with a plastic insert part that pushes against the flare pipe when tightened to create a seal. Its leaking right under the 1/2 nut at the pipe flare dipping down the pipe its not like a fast drip its just a slow drip but yeah its annoying lol. I know when I went to a plumber shop they told me to use 3/8 compression fittings on the pipe and then just hook up a water supply line to it. I don't see a 1/2'' barbed adapter but I do see 3/8 in push to connect I might need to do some more research.

The compression fitting might start leaking if you hit/bend it severely, but not otherwise. My house has had them under all sinks for years and they don't leak. They've been used for decades everywhere.

How do I know if this is legal to use this where I live?

What about larger pipe, such as the half inch copper pipe used for water supply lines to bathroom and kitchen sinks, which feed into shutoff valves below the sink? Are you making the same recommendation against using compression-fitted shutoff valves?

Gotta use plastic compression rings on plastic. They leak frequently on you because the metal digs into the pipe and can’t actually compress.

If you do not put an insert into the end of the 1/4" plastic tubing, yes they will leak, but with the insert, they will not.

And those that leak always lack an insert. If you are skipping the insert, you are asking for fitting failure, and the solution to that problem is to install the fitting with all the components needed and torqued properly. Then sit back and wait to see what happens. Correctly installed compression fittings will not leak and will outlive virtually everyone reading this post.

You showed the barbed fitting with no pipe, then the barbed fitting with the plastic tube connected and finished, but you didn't actually show the plastic being connected, which is the most important part 🤔.

Never use a brass compression ferro on plastic pipe. They make platstic ferro's for that. Slip fittings also have a lock ring you should be using.

Does the manufacturer recommend a clamp to secure the tube on the barb fitting? I know on larger barbs, you usually use some kind of clamp. I'd probably be tempted to grab a tiny hose clamp from the parts bin for that guy just for some extra insurance.

@@diyhvacguy McMaster Carr has almost any fitting or clamp you would ever need. Those barbed fitting are often used for pneumatic controls like actuators and dampers. They usually carry air pressure. I never see them leaking when used with the correct tubing. They should be fine for water, but once again if it’s water and it does leak there could be a major problem. If that tube is in the sun it could get so hot it builds pressure, softens, and blows that tube right off that barb. With air you hear a hissing noise and fix the leak. With water you could be calling your liability insurance company to repair water damage or calling a lawyer when the customer sues. Just saying.
