Nitro Vue Flow Indicator with 1/4” Flare

The Uniweld UW-NV1 NitroVue™ Flow Indicator is a practical nitrogen flow control accessory designed to make HVAC/R nitrogen purging easier, clearer, and more controlled. Built for use during brazing and service work, the NitroVue™ helps technicians visually confirm nitrogen flow, making it easier to protect copper lines from oxidation and scale build-up while working.

The unit features a bright orange float ball and clear viewing tube, allowing technicians to quickly see when nitrogen is flowing. This helps simplify the process of setting and maintaining the correct flow rate for purging and brazing applications. The adjustable needle valve provides precise control over nitrogen flow, giving technicians better confidence during installation, repair, and maintenance work.

Designed for professional HVAC/R use, the UW-NV1 is ideal for use alongside a nitrogen regulator when purging refrigeration and air conditioning lines. Its easy-to-read flow indicator label helps simplify nitrogen setup for both purging and brazing, making it a useful tool for everyday field service.
