The proof is in the piping. Flowing nitrogen while brazing is a MUST in systems that use POE oils. As you can see, the oil scrubs the cupric oxide buildup off the tubing. That black scale circulates through the system as a contaminant and can cause all sorts of trouble. Watch Roman and Ty's latest video where they discuss the potentially deadly consequences (for your compressor) of not flowing nitrogen while brazing.

Reposted from @hvacknowitall1 Pipe prep and nitrogen brazing is very important for joint and system longevity. Reaming, cleaning, N2 purge. In most cases, we'll want to have refrigerant flow towards the swage, but it's understood in the real world that's not always possible. The NAVAC Inc. - HVAC Tools Division NTE11L was used to make the swage. I've ran this Ambro Controls Precision Torch Tip on a couple jobs and it's great for smaller, tight locations, cap lines, etc. First time using the Seal
