Nitrogen flushing tool with easy 3-position control for rinse, solder, and shutdown. Precise pressure performance reduces oxidation, removes contaminants, and stabilizes soldering and flushing operations. Key benefits Fast, reliable control: Three-point position scale (rinse / solder / shutdown) lets you switch modes quickly and consistently so each operation uses the correct nitrogen rate. Saves time on the job: Standard 1/4" quick connector attaches to the outlet of a standard nitrogen pressure regulator for immediate use. When the rinse setting is off, you can attach a standard 1/4" coolant hose and continue rinsing or soldering within seconds. Protects systems and improves quality: Steady nitrogen flow displaces refrigerants and deposits, prevents oxidation during heating, and reduces the risk of equipment failure and rework. Efficient and accurate: Designed to operate with an input pressure of 50 psi and withstand up to 200 psi maximum, providing stable control while minimizing gas waste. Features and performance 3-point position scale: Clearly marked rinse, solder, and shutdown settings for repeatable nitrogen rates for each task. 1/4" connector compatibility: Directly connects to a standard nitrogen pressure regulator outlet and accepts standard 1/4" coolant hoses for fast setup. Pressure range: Intended use with 50 psi input pressure; rated to a maximum of 200 psi for robust, accurate nitrogen control. Function: Facilitates nitrogen penetration into piping during rinsing and soldering to remove contaminants and protect joints from oxidation. Practical applications Refrigeration and HVAC brazing: Purge lines during brazing to prevent oxidation in copper tubing and to remove residual refrigerant and moisture before pressure testing. Field service and maintenance: Rinse and flush pipelines to clear deposits and contaminants prior to system start-up or repair. Manufacturing and assembly: Use during soldering/welding operations where a controlled inert atmosphere is required to protect joints and maintain cleanliness. What it solves Eliminates oxidation and discoloration at joints caused by air exposure during heating. Removes trapped refrigerants and particulate deposits that can cause system inefficiency or failure. Reduces setup time and gas waste with an easy-to-use selector and standard 1/4" connector compatibility. Specifications Control: 3-position (rinse / solder / shutdown) Connector: Standard 1/4" quick-connect to regulator outlet; accepts standard 1/4" coolant hoses Pressure: Designed for 50 psi input; maximum rated pressure 200 psi Stable, accurate control for safer, cleaner flushing and soldering without unnecessary gas consumption.
