3in1 Quick Switch Nitrogen Flow Tool Designed for HVAC professionals who need precise and reliable nitrogen control, this versatile tool makes purging and brazing faster, easier, and more efficient. Key Features and Benefits: Quick Mode Selection Easily switch between three operation modes: Purge mode (2535 SCFH) for clearing lines before service Braze mode (36 SCFH) for lowflow protection during joining Off mode for complete shutoff when not in use Operated by a simple dial, eliminating the need for complicated flow meters or multiple valves. Precision Nitrogen Flow Control Calibrated for performance at 50 PSI inlet pressure (maximum 200 PSI) Ensures correct nitrogen delivery for both purging and brazing Helps prevent oxidation, moisture infiltration, and pipe contamination Contributes to longerlasting and more reliable HVAC systems Durable AllMetal Construction Heavyduty brass body resists wear, impact, and corrosion Designed to withstand jobsite conditions Compact enough to carry in a tool bag, toolbox, or pocket without risk of damage Time and Gas Savings Consistent, preset flows in purge and braze modes reduce waste and improve efficiency No need for repeated adjustments during a job Speeds up service and installation tasks without compromising quality Compatibility: Connects directly to any standard 1/4 inch refrigerant hose Works with standard nitrogen regulators Practical Applications: 1. HVAC line set installation – purge the system quickly before brazing to maintain clean, oxidation copper lines. 2. System maintenance – braze joints with lowflow nitrogen to prevent internal corrosion and extend service life. 3. Refrigerant line retrofitting – easily switch between purge and braze modes when working on split or packaged systems. The 3in1 Quick Switch Nitrogen Flow Tool offers dependable performance, rugged durability, and streamlined operation for professional HVAC technicians who value precision and efficiency on every job.
