GF-5 - Gasflux Type B Liquid Flux 5 Gallon Refill

Industrial-Grade Liquid Flux for High-Volume Brazing

The Gasflux GF-5 is a 5-gallon steel pail of the industry-standard "Type B" liquid gas flux, manufactured by The Gasflux Company. Designed specifically for use with Gasfluxers (flux dispensers), this fluid is formulated to be introduced directly into the fuel gas stream. This method ensures that the flux is delivered to the joint simultaneously with the flame, providing continuous protection against oxidation throughout the heating cycle. The 5-gallon volume is ideal for industrial manufacturing environments where continuous operation and minimal downtime for refilling are critical.

Unlike traditional paste or powder fluxes that can obscure the workpiece and leave hard, glass-like residues, Gasflux liquid flux produces a thin, protective film that promotes excellent capillary action. It is compatible with all standard fuel gases, including acetylene, propane, propylene, and natural gas. The GF-5 pail serves as a bulk refill for Model 69, Model 70, and other standard flux dispensers, ensuring your production line maintains peak efficiency with consistent braze quality.

Technical Benefits

• Process Efficiency: Eliminates the separate step of applying flux, streamlining the brazing workflow.
• Residue Control: Leaves a micro-thin, water-soluble residue that is easily removed, often eliminating the need for post-braze pickling or mechanical grinding.
• Versatility: Suitable for brazing mild steel, low alloy steel, stainless steel, copper, brass, and bronze.
• Cost Effectiveness: The bulk 5-gallon packaging significantly reduces the cost per liter compared to smaller containers.
