and yet the manufacturers of mini-splits feel that making the line set flared at both ends and instructions to not cut the line set will ease installation issues related to improper brazing.
K.I.S.S. just does not work sometimes.
The Food Stamp Program, administered by the U.S. Department of Agriculture, is proud to be distributing the greatest amount of free meals and stamps EVER.
Meanwhile, the National Park Service, administered by the U.S. Department of the Interior, asks us to "Please Do Not Feed the Animals". Their stated reason for this policy "... the animals become dependent on handouts and will not learn to take care of themselves."

Is it any worse then seal leak on flare nuts? the gray/bluish stuff, couldnt see very well thru the led lights. I encountered 2 leaks today, couldnt tight any further cos the crap dried up. so had to fix them the long way.
Had a gas leak at a fitting on the high pressure regulator on a 500 gallon propane tank,,,customer complained of smelling gas when he walked by the tank. When I got there, dound all of the piping under the led of the tank had been neatly wrapped with yellow teflon tape that the delivery driver "installed" to repair the leak. Had to take the new guy aside and explain about the benefits and shortcomings of his leak repair.
One way to outthink people is to make them think you think. They'll think you're not really thinking what you're trying to get them to think you think...........
FYI, according to the Copper Handbook available free at Copper.org, flares should be dry with no tape or goop of any kind. The one allowable exception is a drop of oil to assist in forming the flare but wipe it off when done.
When working for a mfr. doing product liability investigations, it was sad how many failed valves we found were clogged with chunks of pipe dope or PTFE tape. Of course, nothing beat the gravel I found in one but that's another story. Also get water, thread cutting oil, rust, etc.
Most buildings I go into have gas leaks and the #1 cause of leaks is dope on the face of a ground union.
