Brass design Made from robust brass with a red finish, this nitrogen flushing tool is built for longevity and delivers performance compared to typical flow meters. Efficient flushing options Provides effective nitrogen flushing that swiftly clears dust and debris. Easily toggle between rinse, solder, and shutoff modes for nitrogen delivery. Fast setup Connect a standard 14 hose to the shutoff tool kit in seconds, streamlining your rinsing and soldering processes for maximum efficiency. Comfortable and compact Ergonomically designed for ease of use; the compact size fits conveniently in your toolbox, making it portable and easy to handle on the job. Use scenarios Electronics assembly and : Before soldering, flush connectors and pads to remove dust and debris; switch to rinse for cleaning, use solder mode for controlled nitrogen delivery during heating, and shut off flow when finished. PCB maintenance and rework: Use nitrogen during soldering steps to minimize oxidation and improve joint quality; switch between modes as needed to optimize flow and control. Field work in tight spaces: The tool's compact, portable design fits in a toolbox or pouch, enabling quick nitrogen flushing in confined areas.
