Likewise, people ask, 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.
Additionally, how much pressure can a flare fitting hold? POL and Gas Fittings have a maximum working pressure of 250psi.
Keeping this in view, how tight should brake line fittings be?
Brake lines fittings need to be tight, but as others mentioned, too tight and you will pull the threads right out of an aluminum caliper. The critical part is getting the copper crush washers to seal. As you are tightening the bolt, the washers deform slightly, creating a seal.
How does a flare fitting work?
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.
