Solder Wire and Superflo Flux for copper and Brass Piping Systems

It is typically applied before heating the joint. flux can be in the form of a paste or a liquid, and it is used to clean the surfaces and promote proper wetting of the solder. The flux compound contains active ingredients, such as rosin or organic acids, that react with the oxides on the metal surface. When heated, the flux activates and starts to remove the oxides, preventing them from interfering with the soldering process.
