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 | |---------------|-------| | Manufacturer | RX WELDER | | Package Dimensions | 10.72 x 6.71 x 5.21 cm; 132 g | | Item model number | RXNPT-R | | Power Source | gas_powered | | Included Components | 1 X Nitrogen Purge Tool | | Batteries included? | No | | Batteries Required? | No | | Item Weight | 132 g | ## Images ![RX WELD Nitrogen Purge Tool, Hvac Nitrogen Regulator Durable Brass, Red - Image 1](https://m.media-amazon.com/images/I/7187DIUHXDL.jpg) ![RX WELD Nitrogen Purge Tool, Hvac Nitrogen Regulator Durable Brass, Red - Image 2](https://m.media-amazon.com/images/I/61Q18dSke9L.jpg) ![RX WELD Nitrogen Purge Tool, Hvac Nitrogen Regulator Durable Brass, Red - Image 3](https://m.media-amazon.com/images/I/71ZwQWWNbDL.jpg) ![RX WELD Nitrogen Purge Tool, Hvac Nitrogen Regulator Durable Brass, Red - Image 4](https://m.media-amazon.com/images/I/71dzkBjCpCL.jpg) ![RX WELD Nitrogen Purge Tool, Hvac Nitrogen Regulator Durable Brass, Red - Image 5](https://m.media-amazon.com/images/I/71HOVOh2sNL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good value for the money *by A***R on 16 May 2026* I bought this for my hubby.
