For HVAC and refrigeration pros, controlling nitrogen flow during brazing is crucial to prevent oxidation inside copper lines. This WEIDOU purge tool makes it easy with three simple modes: PURGE, BRAZE, and OFF.
Turn the dial to PURGE for high flow to clear the line, then switch to BRAZE for a controlled, lower flow during brazing. The dial clicks audibly at each setting, so you know you’re in the right mode without guessing.
It features an adjustable regulator from 50 to 200 PSI, so you can fine-tune the flow for different jobs. The 1/4\ flare fitting connects quickly to standard nitrogen tanks and hoses.
Built from solid brass and reinforced materials, it’s tough enough for daily use in the field. Compact and lightweight, it fits easily in your tool bag or truck.
Whether you’re installing AC units, repairing refrigeration lines, or doing maintenance, this tool helps you work faster, cleaner, and with better results. A must-have for any serious HVAC technician.
