Nitrogen Purging Tool and Regulator Kit Quick Switching Between Modes Easily switch between three preset modes: purge, braze, and close. Each setting automatically locks in the flow rate, eliminating the need to constantly adjust the flow valve. This ensures consistent performance and saves time during HVAC service work. Precise Flow Control Equipped with a nitrogen purging regulator with an intake pressure of 50 psi and a maximum inlet pressure of 200 psi. Provides accurate and stable nitrogen flow control, achieving reliable purging and welding results while minimizing gas waste. Reduce Maintenance Costs Effectively removes refrigerants, moisture, and debris from pipelines, keeping the interior clean and dry. This helps reduce the risk of equipment failure in HVAC systems, lowering and maintenance expenses over time. Durable, Quality Construction Built from strength allmetal materials for shock resistance, wear resistance, and impact resistance. Designed for longlasting operation under demanding jobsite conditions. Compact enough to store easily in toolboxes, tool bags, or even pockets for quick access. Easy Installation Set the tool to the off position, connect a standard 1/4 inch refrigerant hose, and installation is completed in just seconds. Features an ergonomically designed knob switch for smooth, comfortable operation. Applications 1. HVAC system servicing and installation requiring clean, dry pipe interiors before brazing. 2. Refrigeration maintenance where precise nitrogen purging is essential to protect equipment. 3. Brazing operations that need stable flow control to ensure strong, reliable weld joints.
