Uniweld UNF3 Nitrogen Flow Indicator with 1/4" Female and Male Flare Connections

Uniweld UNF3 Nitrogen Flow Indicator with 1/4" Female and Male Flare Connections

Visually confirm proper nitrogen flow for cleaner, more reliable brazing

The Uniweld UNF3 Nitrogen Flow Indicator provides a simple and reliable way to verify nitrogen flow during copper tube brazing in HVAC/R applications. Designed with a clear graduated indicator tube, the UNF3 allows technicians to visually confirm that nitrogen is actively moving through the system, helping ensure oxygen is displaced from the tubing during the brazing process.

Maintaining nitrogen flow while brazing helps prevent internal oxidation and scale formation that can contaminate refrigeration systems, restrict refrigerant flow, and contribute to premature component failure. The UNF3 makes it easy to distinguish between actual gas flow and static pressure, giving technicians added confidence that proper purging procedures are being followed. Featuring durable brass construction with convenient 1/4" female flare inlet and 1/4" male flare outlet connections, the UNF3 is an effective addition to any HVAC/R brazing setup.
