SPARC Nitrogen Flow Indicator 1/4 SAE Flare Inlet and Outlet 50PSI 2YR USA Warranty
The SPARC Nitrogen flow indicator provides extremely low pressure, precision gas flow control for nitrogen purging applications. This is important during the brazing of copper tubing in air conditioning and refrigeration systems. The nitrogen must be flowing to displace the oxygen inside the tubing during the brazing process, thus preventing internal oxidation and the resulting scale. Scale build-up inside the tubing can cause blockage in the TXV and within the air conditioning and refrigeration system. This results in premature failure. Easy to Read Indicator SPARC's Nitrogen flow indicator uses a float ball to visually confirm the nitrogen is flowing. This is essential during the brazing of copper tubing
