Similarly, why is thread sealing compound not used on flare connections? WARNING - Do not use pipe thread sealant or Teflon® tape on any flare ends because you will not obtain a leak-free seal. Keep flare end of fitting and flare seat of connector nut free of grease, oil, pipe thread sealant and Teflon® tape. -Never loosen a connection after tightening-this may cause a leak.

Also question is, what actually seals the connection in a flare connection?

During assembly, a flare nut is used to secure the flared tubing's tapered end to the also tapered fitting, producing a pressure-resistant, leak-tight seal. The tool used to flare tubing consists of a die that grips the tube and a mandrel that is forced into the end of the tube to form the flare by cold working.

Can you over tighten a flare fitting?

Fourth, don't over-tighten the flare fitting, as this can cause leaks. Daikin offers preset flare torque wrenches that will allow you to properly tighten the flare fitting without over-tightening them. Always use a backup wrench when tightening any flare fitting.
