GF-1 - Gasflux Type B Liquid Brazing Flux Refill 1 Gallon

Premium Liquid Flux for Oxy-Fuel Brazing

The Gasflux GF-1 is a one-gallon refill container of the industry-renowned liquid brazing flux, designed specifically for use with Gasfluxer dispensing units. For decades, metal fabricators and maintenance professionals have relied on this specialized chemical formulation to achieve high-strength, leak-proof braze joints without the mess and inconsistency of traditional paste fluxes. When introduced into the fuel gas stream, this liquid flux vaporizes and is delivered directly to the workpiece through the torch flame. This unique delivery system ensures that the metal is cleaned and protected from oxidation at the exact moment heat is applied, creating optimal conditions for filler metal flow.

This product is ideal for a wide range of maintenance and repair operations, particularly when working with mild steel, stainless steel, cast iron, and copper-based alloys. The "Type B" formulation is the standard general-purpose liquid flux used in most industrial applications. It is engineered to improve the wetting characteristics of bronze and silver brazing alloys, allowing the filler metal to flow smoothly into tight capillaries and across surfaces with minimal effort. This results in stronger joints and a significant reduction in the amount of filler metal required per job.

One of the standout features of using Gasflux liquid is the dramatic reduction in post-weld cleaning. Unlike paste fluxes that leave behind a hard, glass-like crust that must be chipped or ground off, Gasflux leaves a micro-thin, protective residue that often requires no removal at all. If painting or plating follows the brazing process, the residue washes off easily with warm water. This efficiency makes the GF-1 an essential consumable for high-volume production environments and busy repair shops where time is money. By maintaining a consistent supply of flux in the flame, operators can focus entirely on heat control and puddle manipulation, leading to cleaner, more aesthetically pleasing welds.

The 1-gallon plastic jug is designed for easy pouring into the reserve tank of your Gasfluxer unit. It is a volatile liquid and should be handled with care, following all safety protocols for flammable liquids. Whether you are repairing bicycle frames, automotive body panels, or industrial piping, the Gasflux GF-1 ensures your oxy-fuel equipment operates at peak performance.
