Nitrogen Flow Indicator With Adjustable Valve And Bright Orange Float Ball For Precise Low Flow Control Easy Read Label And Purge Copper Lines At Twenty Plus SCFH Then Dial In Three To Five SCFH For Brazing
✔️ Low-flow nitrogen purge from 20+ SCFH to 3-5 SCFH braze
The NV1 NitroVue Nitrogen Flow Indicator delivers precise low-flow nitrogen purging for brazing copper tubing in HVAC&R systems. This single-unit, easy-to-read device pairs with a regulator for steady delivery pressure during brazing, ensuring oxygen displacement and reducing oxidation and scale inside tubing.
✅ Model NV1 NitroVue nitrogen flow indicator with precision adjustable valve for low-flow purging during copper brazing in HVAC&R.
✅ Bright orange float ball visually confirms flow and stages: purge at 20+ SCFH, braze at 3-5 SCFH.
✅ Connects to nitrogen regulator with delivery pressure set at 60 psi to control flow.
✅ Overpressure protection via reseatable safety blow-off that opens at 200 psi.
✅ Color: silver; aids oxygen displacement to prevent oxidation and scale in tubing.
