Videos like this benefit both pros and amateurs alike. Many of us were taught the wrong habits from old timers who never looked at torque specs for example
Ty, lubrication should never be applied to the backside of the flare or the threads. Lubrication on the flare backside and the threads reduces a feature called nut factor or k-factor, which is essentially the level of friction between the rotating parts to the non-rotating parts. The MFR torque specs are for dry threads that have a higher nut factor. Lubrication will cause an over-torque condition. The backside of the flare is NOT a functional seal area so lubricant adds nothing but over-torque risk. I appreciate you guys pointing out that torque wrenches are only calibrated in one direction unless otherwise identified. That direction is clockwise, with the top side of the tool. In the case of click-type wrenches that side is the side that has the MFR logo. This can get confusing in the field when the piping is in the vertical orientation. Click-types can add more confusion since one side of the wrench has imperial torque values and the opposite side has metric values.
Will the Eccentric flaring tool work just as well with aluminum tubing as it does with copper lines? Do you or would you, have the same high confidence in a leak free connection as you do with copper lines? I have a refrigerator where the suction line leaked and have to run a new copper line down the back of the refrigerator. I would like to use the Eccentric flaring tool along with a union to join the copper line with the aluminum EVAP line. I would like to have 100% confidence that it will do the job. For me, in theory, it should work because I have used aluminum gaskets when working with automobile engines. Any ideas? Ty thanks for another great video. The information I have gained about AC from your videos is unparalleled.

That is a great question, I do not know, let me check
Greetings port elizabeth South Africa
Copper gaskets are still very much a thing, still used on vehicles and other things
