It operates optimally at 50 PSI inlet pressure (max 200 PSI) and features three flow settings—off, purge, and braze—for precise nitrogen control. This tool simplifies copper tube preparation by preventing oxidation and contamination, ensuring clean, reliable brazing and purging operations. ## Description Product description Review: Good value for the money - I bought this for my hubby. He has found it to be very useful and the durability is top notch. It was a good value, easy to use. Review: Simple and easy to use. - 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DK1H6R76 | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #42,348 in Automotive ( See Top 100 in Automotive ) #28 in Welding Gas Regulators | | Customer Reviews | 4.7 4.7 out of 5 stars (52) | | Date First Available | October 14, 2024 | | Included Components | 1 X Nitrogen Purge Tool | | Item Weight | 4.6 ounces | | Item model number | RXNPT-R | | Manufacturer | RX WELDER | | Package Dimensions | 4.22 x 2.64 x 2.05 inches | | Power Source | gas_powered | ## Images ![RX WELD Nitrogen Purge Tool, HVAC Brazing Regulator | 50 PSI inlet for smooth purging & brazing flow.
