How to remove compression ferrules from copper pipe


In order to replace drywall behind sink, I'll need to get the nuts and ferrules off the 1/2" copper pipe. How do you get these compression ferrules off?

Grab the nut with pliers and wriggle it as you pull. If the ferrule is not embedded too deep- should work.
Or you go out and buy a ferrule puller

How to remove compression ferrules from copper pipe


I've never been able to get one off and still have a useable surface.
I just cut it off behind the farrel with my ossilating saw and clean it up with a file.

Joecaption has got it right.

Once the ferrule is tightened if it is done correctly it will become part of the tube or pipe that it is secured to. Even if you were to somehow cut the ferrule off you would find that the tube where it was is deformed and will not accept another ferrule without leaking.

You are going to hide the hole with an escutcheon---so leave the nut and use a split plastic escutcheon.

I don't like spelling escutcheon---so I'll leave now --I can spell and the spell check wants things close or it won't correct me----

Cut the pipe 3 inches away and add a coupling.

Are the "press-on" fittings reliable?

Lowes does not carry those, they carry another brand. I'm thinking about using them to cap a water hammer arrestor that I'm shortening- they work on air filled pipes, right?

Is this the ped sink? If the drywall is cut below the tee- why not unsweat the tee and replace it with a 90 and new stub out? Now you don't have to worry about the nuts or lowering the chamber. Plus, you could move the stubs closer together and be hidden behind the pedestal?

Where do you buy a ferrule pulled at?
You a plumber?
Never seen someone pull one off. If it was install right the only way is to cut it off.

Plumbing since the mid 80's- learned to crawl on an 18 story motel project.
I have used pullers several times- almost always been able to reuse the stub out.
First time I bought the tool was about 10 years ago- remodeled a Motel 6 and had only a handful of stops that we couldn't get off with pliers and they were too close to cut.

Yes, he's a plumber---and Yes there is a puller designed to remove the ferrule --and Yes--the pipe is often dimpled by the old ferrule--making that unusable for installing a new one in the same spot
