I reuse/reassemble these things as necessary. To ease future disassembly issues and to make successful assembly happier, I thumb on a smidge of Teflon pipe dope (both to aid the seal and to lubricate the nut). Of course, you cannot slip the old compression ring off and reuse it elsewhere; it will have been reduced in diameter and pressed into the tubing.

"flaring tool $15"

Not if you get a good one from the refrigeration guys.

No body wants a leak , but the refrigeration guys REALLY don't as they will have to come back and service the system .

I've been using Rector 5 on everything even though hydraulic supply told me it wasn't necessary on flared. They said it wouldn't hurt so...why not? It's sitting right there so too easy.

My whole boats fresh water system uses them, and pretty much ok. Problems happen when the copper tubing gets corroded, you try to tighten too much and the fittings can distort, it will drip. I also have used rectorseal T plus 2 teflon thread sealant, and it is really pretty good stuff, although it needs to be used on dry fittings, if wet it doesn't like to stick to the metal. That stuff also works fantastic on rubber hoses, keeps them from sticking to metal, it really works well.

One nice thing, copper pipes kill bacteria and virus, it purifies your water.

In comparison brass is hard and copper is soft. When tightening the flare nut, the flare in the copper is forced to conform to the brass flare fitting. Making a tight seal. I'm 70 and been reusing flare fittings for about 55 years without problems.

If they leak and pop off the answer is yes
