How to install Compression Fittings on plastic tubing

How to insert Compression Fittings on plastic tubing only for water application

[alanrodgers]

Thank you very, very much. one small orientation of the plastic insert made the whole difference for me. I spent hours and hours trying to identify why it was leaking and it seems like the plastic sleeve’s tapered one should face the end of the tube.
That fixed it.
Thanks again!

This is correctly done. Note the direction of the Delrin sleeve. The tapered side towards the end of thd tube, the bulky side toward the nut. You want the Delrin to wedge into the brass fitting. Also, fully insert the tubing into the compression fitting before tightening the nut. It wasn’t clear if that was done in this example but it looked good enough.

Thank you for sharing. Short, sweet and straight to the point.

This solved my issue, my package came with the brass compress sleeve tapered identically on both ends, I needed to use the plastic one with the tapered side facing inwards. Thanks

Give this video a thumbs up bc I've been doing it wrong my whole life. Never knew what that long insert was for!! Genius!

[davidvanseters]

This was exactly the information I needed! Thanks so much

[stefanhoffman]

oh i see. All I did wrong was everything.

This was the type of instruction I was looking for. Thank you.

You can use a brass ferrule (sleeve, olive) on plastic tubing, but you must use the insert provided and not over tighten. The brass ferrule type is not tapered, but is symmetrical . The insert is pictured in the video and is the piece which is pushed INTO the plastic tubing.

Great vid! Also felt like I was in a massage with the music, so relaxed I won't beat up my water line now.

Do I need a plastic ferrule when I'm using plastic tubing? The package I bought had a brass ferrule and the tube still slides out no matter how hard I tighten it. Thanks

Thank you for your precise, concise and clear presentation.

Thank you for saving me 😊. I was missing the plastic ferrule that I had taken off from the old set up. I put it like you showed and the tubing stopped popping off.

Just a heads up, i bought a packet with that metal insert at Depot and it was slightly too big. A plumber gave me one that is a fraction smaller but fits into my water tube a lot better. Not sure what to look for on the packaging.

I plan to use this for my RO system so I wont have to drill threw the counter, thanks for the vid

Okay cool, does this part go into the fridge or the water line under the sink?

Does the brass insert need to be a glove fit? I’m doing these steps and it’s not staying connected and I swear I bought all the right sizes but something doesn’t seem to be lining up. 3/8 inside diameter tubing and 3/8 outside diameter brass insert but it seems loose

[utmhernando]

Thanks 👍 this worked for me. Definitely need 2 wrenches and I used some Teflon for a tighter seal

[DimaProk]

can you use this for softer vinyl tubing? I am trying to create leak proof connection of vinyl tubing to copper tubing.

My Brasscraft compression shutoff valves say in the online info: "On PEX 3/8 in. OD and smaller, use plastic compression sleeve. On tubing larger than 3/8 in. OD, use brass compression sleeve w/stainless steel tube insert." So I'm going by that on my Delta faucet lines.
