• Simple 3mode control for faster, safer work Clearly labeled dial with PURGE, BRAZE, and OFF positions lets you switch modes quickly on the job. Use PURGE to displace oxygen from the line before heating, BRAZE to hold the purge while joining, and OFF when finished. • Built to last in the field Constructed from brass and reinforced materials for corrosion resistance and impact durability. Engineered to withstand tough jobsite conditions and deliver reliable, longlasting performance. • Improves brazing results and reduces rework Maintaining a nitrogen blanket during brazing helps minimize oxidation and scale inside tubing. That protects joints, improves flow characteristics, and reduces the need for cleanup or after brazing. • Portable, lightweight design Compact profile fits easily in a service truck or toolbox. Lightweight construction makes it convenient to carry between sites and work in tight spaces without adding bulk to your kit. • Audible click for confident operation The dial produces a clear audible click when switching modes, giving instant, reassuring feedback so you know the tool is set correctly even when visibility is limited. • Clear compatibility and professional use Designed for HVAC professionals and intended for use with nitrogen purge setups common to HVAC brazing and service work. The tool supports standard field brazing and purge workflows without added complexity. Typical applications Brazing copper refrigeration or air conditioning lines: purge oxygen from the tubing to prevent oxidation while joining fittings. Field service and rooftop unit repairs: lightweight portability and robust construction make it ideal for maintenance, replacements, and emergency repairs. Retrofit and install jobs in confined spaces: small footprint and audible mode confirmation help technicians work efficiently in tight or noisy environments. What you get A durable, easytouse nitrogen purge tool that simplifies mode switching, protects joints during brazing, and fits comfortably into a technician's kit.
