97000 - General Purpose Soldering Flux Paste - 4 oz Can

Professional Grade Flux for Soft Soldering

For welders and fabricators who occasionally handle soft soldering tasks, having a dependable flux is non-negotiable. The General Purpose Flux Solder (4 oz Can) offers the industrial-grade performance required for consistent, high-strength joints. Soldering relies heavily on chemical preparation; without a proper flux, oxidation on the metal surface acts as a barrier, preventing the filler metal from bonding. This advanced paste flux is engineered to aggressively clean these oxides at soldering temperatures, promoting rapid wetting and excellent capillary action.

This product is particularly effective for maintenance and repair operations (MRO) where versatility is paramount. It can be used on a multitude of base materials, including copper piping, brass fittings, sheet metal, and mild steel components. Unlike acid cores or liquid fluxes that can be difficult to control, this paste allows for precise application. You can coat the joint area thoroughly before applying heat, ensuring that the flux protects the metal from further oxidation during the thermal cycle. The result is a bright, shiny, and mechanically sound connection that stands up to service conditions.

Safety and efficiency are built into the formulation. The flux is designed to minimize sputtering and fuming when used correctly, providing a better working environment. The 4 oz container is durable and resealable, preventing the flux from drying out or becoming contaminated between uses. For professionals seeking a robust solution for their soldering needs—whether for HVAC installations, radiator repairs, or custom metalwork—this general-purpose flux delivers the reliability expected in a professional shop.

Technical Advantages

• Oxide Removal: Aggressive cleaning action prepares dirty or oxidized metal surfaces.
• Thermal Stability: Remains active throughout the heating cycle to protect the joint.
• Broad Compatibility: Works with tin-lead, tin-silver, and other common soft solder alloys.
• Controlled Application: Viscous paste prevents dripping and running for precise placement.
