I am removing a sink and trying to cap off the copper supply line. I have easy access to where it branches off, and it uses a compression tee there. I think the cleanest thing would be to just undo it's branch from the compression fitting and put what I've seen called a "compression cap" on the threaded connection there.
I understand that a a normal compression fitting uses the ferrule to seal. But, how do these end caps work when there's no pipe underneath them? Do I need to use tape or dope? Do I put a washer under there?
Thanks
