There is supposed to be a brass compression ring on the outside of the plastic tube that tightens and seals the fitting as you tighten the nut. There is a brass insert that goes inside the pipe to help it keep its shape.

So if this was brand new and you were assembling it, you would slip the nut over the plastic pipe first. Then you would slip the compression ring over the plastic pipe. Then you would insert the brass insert into the pipe. The compression ring slides to the tip of the pipe. Then the nut is brought up behind it and you tighten the nut down. No Teflon tape or sealant is required. But you should use 2 wrenches. One to hold the shutoff stationary while the other wrench tightens the nut.

I am concerned at the amount of Teflon tape I see on the fitting. This type fitting does not use any.

This image might help. I'm hoping there is a ferrule underneath that nut.

I see...... so I gently pulled it out and this is what I see... i guess the whole fitting failed? can i cut the tube and then use the fittings again, or just purchase a new fitting?

They are just called 1/4" compression fittings, very common!

I would also advise to replace that tubbing if it's more than a couple years old, cheap tubing can become brittle and crack and cause a leak, ask me how I know!

Try disassembling it and following the directions. When you get the nut off, clean threads off with a wire brush. If there is no brass compression ring in there when you take it apart you will need one.

I would splurge for a new inner tube and compression ring. If the nut is in decent condition, no need to replace it.

For example, but your local hardware store should have them in stock.

As mentioned, clean the threads the best you can and don't use any tape or dope on it. Just tighten about a 1/4 to 1/2 turn past tight. You should be able to pull on the tube and it not come out.

Still not sure you need to buy anything. You should be able to disassemble and reinstall it correctly.
