ESAB Victor 0386-1397 Viper A45 High Silver Brazing Alloy

The ESAB Victor Viper A45 High Silver Brazing Alloy (MPN: 0386-1397) is a premium 45% silver brazing filler metal engineered for strong, reliable, and leak-tight joints across a wide range of base metals. Trusted by HVAC technicians, plumbers, refrigeration specialists, and industrial fabricators, the Viper A45 delivers excellent flow characteristics and consistently high joint strength in demanding applications.

Key Features:

• 45% Silver Content – High silver composition provides superior tensile strength and ductility in brazed joints
• Excellent Fluidity – Flows smoothly and uniformly at brazing temperatures for complete joint fill and minimal voids
• Wide Base Metal Compatibility – Suitable for brazing copper, brass, bronze, steel, stainless steel, and nickel alloys
• Cadmium-Free Formula – Safer for operators and compliant with environmental and occupational health standards
• ESAB Victor Quality – Manufactured to strict industry specifications for consistent alloy chemistry and performance batch to batch
• Ideal for HVAC & Refrigeration – Commonly used for joining refrigerant lines, copper tubing, and fittings requiring pressure-tight seals

The Viper A45 brazing alloy is typically used with an appropriate silver brazing flux and an air-acetylene or oxy-acetylene torch. Its low working temperature relative to lower-silver alloys helps minimize heat distortion on thin-walled tubing and precision assemblies. Whether used in production environments or field service, the ESAB Victor 0386-1397 Viper A45 is a professional-grade solution for high-integrity brazed connections.
