Everflux HARRIS40022 Stay-silv White Brazing Paste Flux 6.5 Oz Bottle with Brush Cap

Product Description

The Everflux HARRIS40022 Stay-Silv White Brazing Paste Flux is a professional-grade brazing flux designed for use across a wide range of base metals and high-temperature brazing applications. Packaged in a convenient 6.5 oz bottle with a brush cap, this flux delivers smooth, consistent application with every use. The brush cap design allows technicians to apply the paste directly and evenly without additional tools, saving time on the job and reducing waste. This product is well suited for HVAC technicians, plumbers, pipefitters, and other trade professionals who regularly perform brazing work on copper tubing, refrigerant lines, gas piping, and structural metal assemblies. The formulation is a homogeneous mixture of boric acid and fluoride compounds. This combination produces a smooth paste that spreads evenly over base metal surfaces, providing thorough coverage before and during the brazing process. The flux actively protects the joint area from oxidation throughout the entire braze heating cycle, helping to ensure strong, clean, leak-free connections. The activity range for this flux is 1050 to 1600 degrees Fahrenheit, which corresponds to 566 to 871 degrees Celsius. This range makes it compatible with most common silver brazing alloys and oxy-acetylene or air-acetylene torch setups used in plumbing and HVAC work. Approved base metals include copper, copper alloys except aluminum bronze, steel, stainless steel, nickel alloys, and other ferrous base metals. This flux meets multiple industry standards including AWS A5.31 Classification FB3-A, AMS 3410, Federal Specification O-F-499 Type B, and EN 1045 Type FH10. It is manufactured in the USA, making it a reliable choice for professionals who prioritize domestic-sourced materials. Whether used in commercial refrigeration, residential HVAC, or industrial pipe fabrication, the HARRIS40022 delivers consistent flux performance that supports high-quality brazed joints every time.
