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.

High temp brazing without flowing Nitrogen can lead to cupric oxide buildup inside the copper tube which can clog the filter drier or strainer screen and reduce lubrication at the moving parts such as at the compressor. Acidic flux within the tubing can react with the POE oil and cause more acidic buildup and eat away at the resin separating the compressor winding wires!
