Uniweld NV1 NitroVue Nitrogen Flow Indicator with Adjustable Valve and 1/4" Flare Fittings

Nitrogen Purging Simplified

The NitroVue™ NV1 Nitrogen Purge Flow Indicator makes it easy to properly purge and braze copper tubing in air conditioning and refrigeration systems. Its easy-to-read flow indicator label and precision adjustable valve help technicians quickly set the correct nitrogen flow rate, while the bright orange float ball provides instant visual confirmation that nitrogen is actively flowing through the system. Built with a rugged aluminum body and wide viewing windows, the NV1 allows users to easily monitor flow during both the initial purge and brazing stages.

By maintaining proper nitrogen flow, the NitroVue™ NV1 helps prevent internal oxidation and scale formation that can lead to restrictions, TXV blockages, and premature system failures. A reseatable safety blow-off protects the unit from overpressure conditions above 200 PSI, while the adjustable flow control helps conserve nitrogen usage and reduce operating costs.
