Pipe dope and/or teflon tape
Not necessary, but recommended along with pipe thread compound.
You do not need tape on any flared fitting, brake or regular. The brake line and the fittings are different size and thread type than regular copper line and fittings. You can't mix them.
Many fittings, except unions, require the use of teflon tape.
Yes, otherwise you will have leaks
Typically, 3 to 5 wraps of Teflon tape should be used when sealing pipe fittings.
Teflon tape should be wrapped in a clockwise direction around the threads of a pipe or fitting to ensure a tight seal.
Pipe dope better solution than tape.
The best method for sealing pipe joints is using Teflon tape.

With a wrench
No, teflon tape (and pipe dope, for that matter) should never be used on flare fittings. They are designed to seal without tape or dope, and may actually leak if tape or dope is used.
If you are running natural gas or propane, gas teflon tape. Otherwise, any white teflon plumbers tape is fine.
Both Teflon tape and pipe dope are effective methods for sealing pipe joints. Teflon tape is easier to use and less messy, while pipe dope provides a more secure seal. The best method depends on the specific application and personal preference.
Plumbers tape and Teflon tape are both used to seal pipe joints, but they have different compositions. Plumbers tape is made of a thin metal strip, while Teflon tape is made of a thin, flexible material. Teflon tape is more effective for sealing pipe joints because it is more flexible and can conform to the shape of the joint better, creating a tighter seal.
Pipe joint compound or Teflon tape
Pipe thread sealant and Teflon tape are both used to seal pipe threads, but they work in different ways. Pipe thread sealant is a liquid compound that hardens to create a seal, while Teflon tape is a thin, flexible tape that is wrapped around the threads to create a seal. In general, Teflon tape is more effective for sealing pipe threads because it provides a tighter seal and is less likely to leak.
