SPARC Nitrogen Flow Indicator 1/4 SAE Flare Inlet and Outlet 50PSI LIFETIME USA Warranty -> Nitrogen Flow Indicator with 1/4 SAE Flare Inlet and Outlet, 50PSI, Lifetime Warranty

The SPARC Nitrogen flow indicator offers precise gas flow control for nitrogen purging applications at extremely low pressure, which is crucial for brazing copper tubing in air conditioning and refrigeration systems. Maintaining flow of nitrogen during brazing is essential to displace oxygen inside the tubing, preventing internal oxidation and the resulting scale that can cause blockage in the system. SPARC's Nitrogen flow indicator features a float ball to visually confirm the nitrogen flow, allowing technicians to flush copper lines at 25-35 CFH and then reduce flow to 3-4 CFH during brazing, conserving nitrogen effectively. The product has a maximum inlet pressure of 50 PSI and must be connected to a nitrogen regulator with a 1/4" male flare outlet connection for gas pressure control. It is compatible with UNIWELD RHP400, RHP500, RHP750, and similar style regulators.

With a 0-75CFH flow output at 50 PSI, the SPARC Nitrogen Flow indicator has a 1/4" SAE female flare inlet connection and a 1/4" SAE male flare outlet connection. The indicator's ability to provide extremely low flow with high precision gas control makes it safe to use, and it is equipped with an over-pressure safety relief rupture disk for added customer safety. The product comes with a lifetime warranty and dedicated support from industry veterans in Denver, Colorado.
