Do you need pipe dope for brass to brass?
Yes, it is still a pipe thread. The pipe dope is there to fill in the gaps in the thread. It is impossible to machine the treads close enough in pipe to not need something in the threads to make a seal.

In pipe fitting sizes such as -4AN what does AN stand for?
AN stands for Army Navy. The AN fittings have a 37 degree conical end which is what makes the seal.
What are ferrules used for in plumbing?
A ferrule is used on a compression type joint. Care should be taken to properly tighten the nut, but typically it goes between the nut and a fitting. You should use plastic ferrules on plastic pipe but also be sure to use a brass or stainless sleeve inside the open end of the pipe so you don't crush it and it maintains therigidity of the pipe. You should use a brass ferrule on copper pipe which are stronger and give a better squeeze on the pipe sealing the joint. Usually hand tight plus a 1/2 turn is good to start with. water test the fitting and if it leaks you can always shut it back off and tighten more. One rule of plumbing is tight is tight, too tight is broke! There is no need to apply pipe sealant, pipe dope, or Teflon tape to the threads of the compression nut. None of these things will hurt, but they won't help either, since the seal depends ONLY on how well the ferrule is compressed against the pipe and the taper of the fitting. If the fitting leaks, it is because something is wrong. You could have over- or under-tightened the nut, the ferrule might have been damaged, the taper might have a nick in it, etc.
What is pipe grooving?
Pipe grooved at end of pipe with grooving machine. Butt grooved pipe or fitting together and slip rubber seal onto end of each grooved joint, apply light coating of grease made for grooved piping on rubber seal. Coat split coupling for joint with grease also and put coupling around joint and clamp together tightly.
What is flare copper pipe?
When soft copper tubing is used the end is flared so that it can seal against the fittings. A flaring tool is used to spread the end of the tubing so that it looks like a small funnel. When you tighten the nut onto a fitting it compresses the copper against the flare on the fitting and makes a seal. It is a dry seal, no pipe dope should be used on a flare fitting. This is almost always on a gas line of some sort, air, natural gas, propane or some other gas. It can be used for liquids, but generally isn't.
How do you tighten a loose pipe fitting?
Turning a screw, opening a jar or bottle, operating a faucet, and adjusting a plumbing fitting all function on the same principle. Turning to the left loosens the plumbing fitting; turning to the right tightens it. Remembering this simple rhyme can prevent a bad seal and stripped fittings.

How do you clean pipe thread compound TFE paste off of pipe threads?
It is spread on the threads of pipe before being screwed into a fitting so that the threads will make a seal. Since pipe threads are not machined to fit together perfectly the paste makes up the difference and is compressed between the grooves on the two halves.
How do I stop water leak connecting plastic line to metal shut off?
This is a compression fitting and sometimes the plastic line deforms and does not seal. You can use an insert inside the line and either a plastic or brass feral on the outside. The insert is a small brass tube that fits inside the plastic tubing. This keeps the line straight so that the feral will seal all the way around.
Tape for plumbing fixtures?
Plumber's Tape is a non-adhesive strip of plastic that is wrapped around the threads of a pipe before attaching it to a fitting. The extra material in the threads makes for a more watertight seal.
Does a compression fitting have to be replaced on copper pipe to hook up a dishwasher and if so how do you get the old one off?
Compression fittings unscrew. Inside you will find an 'olive' (a thin copper ring) which is compressed onto the pipe to create a seal when the outer nut is tightened up. If you wish to replace the compression fitting then you may need to use a junior hacksaw to saw through & remove the olive - be careful not to cut into the pipe unless you wish to replace it too. As for the dishwasher I would guess that you could use the same fitting unless it is leaking. If it is leaking then replace the olive as above.
What is U Seal in pipe fitting?
It appears to just be another type of O-ring. I think it's because they have the shape of an inverted bicycle tyre, with a u-shaped ridge dipping in all around the outside.
