Tandefio 40 Sticks Brazing Rods – 15% Silver Solder for HVAC

Efficient brazing for HVAC, refrigeration, and more

Meet Tandefio's 40-sticks brazing rod set, crafted with a 15% silver alloy designed for dependable joins on copper pipes and related components. Each rod measures 0.050 inches in diameter with a 10-inch length, and the pack provides ample material to tackle multiple projects without frequent restocking. The alloy balance supports smooth flow into narrow gaps, helping you achieve consistent joints with minimal fuss.

What makes this alloy appealing is its balance of flow and strength. The silver content helps the liquid weld fluid to wet into tight gaps, creating joints that feel robust and consistent, while the comparatively moderate melting behavior can simplify the heating process. This means you may experience smoother soldering sessions with fewer interruptions for rework, especially when working in confined spaces or on small-diameter piping.

Key benefits at a glance

• 40 rods per pack to cover multiple repairs and installations
• High-quality 15% silver alloy designed for reliable brazing in copper systems
• Improved wettability and stronger joint integrity for durable connections
• Balanced temperature profile for practical heating control during brazing
• Dimensions: 0.050" diameter by 1/8" thickness and 10" length per rod

Ideal use cases

• Replacing split copper pipes in home air conditioning units
• Servicing commercial refrigeration systems and cold storage equipment
• Repairing refrigeration system accessories within filters and water lines
• General brazing tasks in HVAC projects where strong, leak-resistant joints are desired

How to get the best results

Before brazing, prepare the surfaces by removing grease, oxides, and contaminants. Clean, dry joints heat evenly, then apply the brazing rod with steady, uniform motion to fill the gap. Maintain joint gaps around 0.002 to 0.006 inches for dependable fluid flow, and monitor temperature to avoid overheating.

Notes: This alloy has a solidus near 1193°F (645°C) and a liquidus near 1472°F (800°C). Actual results may vary based on equipment and technique, so adjust heat and cleaning steps as needed. The packaging contains 40 rods to support multiple tasks without interruption.
