SPARC Nitrogen Flow Indicator 1/4" Flare Inlet and Outlet 50PSI 2YR USA Warranty
SPARC Nitrogen Flow Indicator 1/4" 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 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, 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 resulting in premature failure. The Nitrogen Flow Indicator uses a float ball to visually confirm the nitrogen is flowing and allows the technician to first flush the copper lines at 25-35 CFH and then reduce the flow to 3-4 CFH during the brazing process thus conserving and saving nitrogen. If the ball does not rise in the tube there is no flow of nitrogen only static pressure and oxygen is not being displaced. The maximum inlet pressure is 50 PSI and must be connected to a Nitrogen Regulator with 1/4 inch male flare outlet connection (SPARC SP00021 – Sold Separately) to control the nitrogen gas pressure. Is compatible with UNIWELD RHP400, RHP500, RHP750 regulators as well.
