Solder & Flux

Stop leaks, fix wiring or sweat fittings without fighting oxides. We stock solders and fluxes that wet fast and bond strong: rosin core and rosin flux for clean electrical joints, acid core and gelled or liquid flux for plumbing, radiators, sheet metal and mixed metals. Grab solid wire when you need more fill, paste for quick, even flow.
