• HANDS-FREE BRAZING: Nitrogen purging creates a stable seal on copper tubing, helping reduce oxidation during heating and cooling repairs without tape or manual hose holding
• AIRTIGHT O-RINGS: Internal O-rings grip tubing firmly to block outside air, supporting cleaner joints and steady gas flow for refrigeration brazing tasks
• QUICK 1/4IN CONNECTION: Fits common regulator hoses for fast setup and leak-resistant operation, helping Hold low-pressure nitrogen during single-tech servicing
• STEPPED TUBING FIT: Designed for 3/8in to 1-1/8in tubing sizes except 1/4in, for refrigeration lines with smooth deburred pipe ends
• PROTECTIVE STORAGE CASE: Includes a clear case to shield seals and fittings during transport, keeping Blowing tools organised and ready for the next heating job

Features: Hands-Free Nitrogen Purging for Cleaner Brazing：Engineered for heating and cooling systems and refrigeration brazing – creating a stable, hands-free seal on copper tubing without tape, holding hoses, or gas leaks. Maintains a steady low-pressure nitrogen flow during brazing – reducing internal oxidation for cleaner joints. Tight O-Ring Seal Prevents Air Infiltration：Features multiple internal O-rings that clamp firmly onto copper tubing – forming an airtight seal that blocks external air from entering the system. This keeps brazed joints clean and oxidation-free. The O-rings are long-lasting but are not replaceable due to their precision-fit design. Standard 1/4" standard Connection – Quick Installation：Equipped with a standard 1/4" standard fitting – connecting directly to common nitrogen regulator hoses. The quick, leak-free setup saves time, especially for single-person operation – eliminating the hassle of tape or handheld purging. Stepped Design for Multiple Tubing Sizes：Fits 3/8", 1/2", 5/8", 3/4", 7/8", and 1-1/8" outer diameter ACR copper tubing. Note: Not for 1/4" tubing. For refrigeration tubing only – for ensure tubing is deburred before use; not for bent or oval tubing. Keep nitrogen pressure below 20 PSIG for safe operation. Protective Storage Case Included：Comes with a clear storage case that protects internal O-rings and the 1/4" standard fitting when not in use. Keeps the tool organized in your heating and cooling systems kit, avoids damage during transport, and keeps the nitrogen purge sleeve ready for the next job.
