| Why Purge With Nitrogen? Nitrogen purging:  When brazing copper, it is imperative to purge with nitrogen in order to minimize or eliminate oxidation that results from heating the copper pipe.  Without purging, oxidation will occur and the oxidized flakes that result can and will break off and flow through the system, damaging bearings and fouling system filters.  All that is needed is a low pressure, low volume flow of nitrogen.  The use of dry nitrogen gas also minimizes the need to evacuate moisture from the system. |
![]() Complete Nitrogen Purge Kit, ( 0386-1370 ) The TurboTorch Nitrogen Purge Kit is designed with the professional in mind.  This kit gives you the tools to pressure check HVAC and Refrigeration lines, flush drainage lines, blow clean components, and purge lines prior ro brazing the joints from oxidation. |

Nitrogen Flow MeterThe NFM-TT Nitrogen Flow Meter allows for a controlled flow of nitrogen gas through copper lines during brazing and provides a visual confirmation of gas flow. &nbsPurging the line with nitrogen prevents oxidation and scale inside the tube which would otherwise cause contamination.
