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

The Professional's Choice for Clean Brazing

If you do a lot of brazing, you know that stopping to dip your rod in flux or brushing on paste can break your rhythm. The Gasflux 5 Gallon Pail (GF-5) is the ultimate refill solution for your shop's flux dispenser. This is the famous blue liquid that turns a standard oxy-fuel torch into a precision brazing tool. By feeding the flux right through the flame, you get a bright, green-hued flame that cleans the metal as you heat it, letting you see the puddle clearly without fighting through a crust of burnt paste.

This 5-gallon supply ensures you won't run dry in the middle of a big project. It works with your existing Gasfluxer to deliver the exact amount of flux needed—no more, no less. The result is a braze joint that looks like TIG: smooth, clean, and incredibly strong. Plus, the cleanup is a breeze. While paste flux leaves a rock-hard glass slag that ruins grinding wheels, Gasflux residue usually wipes off with warm water or a wire brush.

Why Welders Prefer Liquid Flux

• Superior Visibility: No white powder cloud or thick paste to block your view of the joint.
• Better Penetration: The flux flows ahead of the alloy, pulling the silver or bronze deep into the joint.
• Less Mess: Say goodbye to chipping hammers and heavy grinding; the finished joint is nearly clean right after cooling.
• Consistent Results: Because the flux is in the flame, you can't accidentally skip a spot or apply too little.
