69080163 - All-State Duzall Liquid Soldering Flux - 1 Gallon Jug

Heavy-Duty Liquid Flux for Industrial Soldering

The ESAB All-State Duzall Liquid Flux is a premium, general-purpose soldering chemical designed to meet the rigorous demands of industrial maintenance, repair, and fabrication. Supplied in a cost-effective 1-gallon container, this flux is engineered for high-volume workshops that require consistent, reliable results across a wide variety of base metals. Duzall is formulated as a highly active acid-based solution, making it exceptionally effective at breaking down tenacious oxide layers that typically hinder the soldering process.

One of the primary strengths of Duzall is its versatility. It is compatible with virtually all metals commonly found in MRO environments, including stainless steel, chrome, monel, copper, brass, bronze, cast iron, steel, galvanized iron, lead, zinc, nickel, and silver. This broad compatibility range allows facilities to consolidate their chemical inventory, using a single high-performance flux for multiple soldering applications. The only notable exceptions are aluminum and magnesium, for which specific fluxes are required. The liquid consistency allows for easy application via brushing, dipping, or squirting, ensuring deep penetration into joints for optimal capillary action.

When heated, the flux activates instantly to clean the metal surface, allowing the solder to flow smoothly and adhere firmly. It works seamlessly with all standard soft solders, such as tin-lead, tin-antimony, and tin-silver compositions. Because the flux residues are corrosive, it is critical to clean the workpiece after soldering. Fortunately, the residues are water-soluble and can be easily removed with warm water, leaving a clean, finished joint. For professionals seeking a robust solution for difficult soldering tasks—such as joining stainless steel to copper—All-State Duzall remains the industry standard for performance and reliability.

Key Industrial Benefits

• Universal Application: Solves joining problems on almost any metal combination (excluding light metals).
• Deep Cleaning: Acidic formulation cuts through rust, dirt, and oxides to prepare the surface.
• Cost Efficiency: The 1-gallon bulk packaging reduces unit cost for busy production lines.
