HANDS-FREE NITROGEN PURGING FOR CLEANER BRAZES: Designed for HVAC and refrigeration brazing, this nitrogen purge boot provides a stable, hands-free seal on copper tubing—no tape, no holding the hose, and no air leaks. Perfect for maintaining a steady low-pressure nitrogen flow during brazing to reduce oxidation inside the line

TIGHT O-RING SEAL PREVENTS AIR INFILTRATION: This nitrogen purge tool is built with multiple internal O-rings that grip copper tubing firmly to create an air-tight seal. This prevents outside air from entering the system and ensures cleaner, oxide-free brazed joints. O-rings are durable and long-lasting, but cannot be replaced due to the precision fit

STANDARD 1/4” SAE CONNECTION – FAST SETUP: MyClenkpro nitrogen purge boot features a standard 1/4" SAE fitting that connects directly to common nitrogen regulator hoses. Provides a fast, leak-resistant setup that saves time—especially helpful when working alone compared to taping or hand-holding purge lines

STEPPED DESIGN FITS MULTIPLE TUBE SIZES: MyClenkpro nitrogen purge boot works with 3/8”, 1/2”, 5/8”, 3/4”, 7/8”, and 1-1/8” OD ACR copper lines. Please note: NOT designed for direct use on 1/4” tubing. Usage Notice: Designed for refrigeration tubing; ensure tubing is deburred before use; not suitable for bent or oval tubes; keep nitrogen pressure below 20 PSIG.

INCLUDES CLEAR PROTECTIVE STORAGE CASE: Includes a clear storage case to protect the internal O-rings and 1/4" SAE fitting when not in use. Keeps the tool organized in your HVAC bag, helps prevent damage during transport, and ensures the nitrogen purge boot is always ready for the next job
