Plumbing Fluxes
Superior Flux manufactures a full range of plumbing fluxes: water-soluble paste flux, petrolatum paste flux, tinning flux, and rosin paste flux. All are excellent choices for soldering copper pipes and can also be used as general purpose soldering fluxes.
If you are interested in having these products packaged and labeled per your specifications, please learn about our Private Label Flux Program.

Superior No. 130 is a petroleum-based plumbing flux paste that contains Zinc Chloride and Ammonium Chloride. The petroleum helps protect the solder joint against corrosive attack, and its paste form insures that the flux stays put until soldering.
Superior No. 135 is a rosin/petroleum soldering flux paste. The petrolatum helps protect the solder joint against attack, and the rosin leaves a protective coating over the solder area after soldering.
Superior No. 141 is a unique, water-soluble plumbing flux that is an excellent alternative to petrolatum fluxes and meets NSF/ANSI Standard 61. No. 141 is a creamy, white paste that holds its form and will not slump until being heated above 50°C/122°F. This flux promotes excellent solderability and post-solder residue removal where copper and copper-alloy tubes are being soldered with lead-free alloys.
Superior No. 70-5 is a petroleum-based tinning flux. With the addition of tin into the flux-base, this flux leaves a coating of tin on the solder area that improves the base-metal joining.
