Rubyfluid Soldering Flux                         (SDS) (SPEC)

Ruby Fluid Soldering and Tinning Flux is a versatile general purpose flux that is used in numerous applications, including stained glass, plumbing, roofing, electrical and many others. This organic acid flux causes solder to flow in a thin film, thus saving solder. Ruby flux adheres quickly when applied and stays put where applied.
