## Overview

The RX WELD Nitrogen Purge Tool is a professional-grade HVAC regulator designed for precise nitrogen flow control during purging and brazing. Featuring a durable brass body, it supports an optimal 50 PSI inlet pressure (up to 200 PSI max) and offers three flow settings—off, purge, and braze—allowing technicians to efficiently remove moisture, refrigerant, and debris to prevent oxidation and equipment failure. Lightweight and easy to connect with standard 1/4-inch hoses, it’s the essential tool for clean, reliable copper tube preparation.

## Description

RX WELD Nitrogen Purge Tool, Hvac Nitrogen Regulator Tool, Nitrogen Regulators, Durable Brass, Red

Review: Way cheaper than supply houses try to rip you off for and the exact same product it regulates the flow post regulator seems to twerk so twerk it your worth it.
Review: Can be used to maintain test pressure of 150 pounds with a slow feed, while searching for a small leak. Instructions say 150 pounds maximum. Has three settings: off, purge (slow) and braze (faster). Purge and braze can be sped up or slowed down by regulating feed pressure to the device. I found that a slow purge requires only a low feed pressure to this device, just enough to get the pressure regulator to flow to it is enough. The braze setting has a much higher flow rate than I expected.

## Features

- 50 PSI Inlet Pressure: Designed to function optimally with a 50 PSI inlet pressure, while accommodating a maximum inlet pressure of 200 PSI, ensuring effective purging and brazing operations
- Easy to Use: Easily prep copper tubes for blowing and brazing by setting the tool to shut off and connecting standard 1/4-inch refrigerant hoses in just a few seconds
- Function: Helps nitrogen flow smoothly into tubing during purging and brazing, removes refrigerant, moisture and debris, prevents oxidation and equipment failure, and keeps tubing clean
