Plumber's Flux

Oatey flux and solder pastes facilitate the soldering process by eliminating dirt, surface oxidation and other impurities from the soldered joint. Flux helps create a strong, long-lasting bond by promoting a better flow of solder and preventing oxidation during heating. Oatey fluxes and pastes are lead-free and come in a variety of formulas, including water-soluble and thinning, to meet the needs of different copper installation applications.

Choosing the right flux is an important step in the soldering process. For example, water-soluble fluxes are ideal for potable water lines since they can be easily cleaned away after soldering, leaving behind a clean and contaminant-free connection. Elevate your soldering precision with Oatey flux.

Frequently Asked Questions

What is the difference between #5 and #95 fluxes?

The #95 paste flux contains a silver solder tinning powder which helps fill in the joint when heat is applied, #5 does not.

What type of solder and flux should I use to solder stainless steel?

None. Oatey does not manufacture a solder or flux for this application.

What is the difference between water soluble and non-soluble (petroleum base) flux?

The water soluble flux is less corrosive, and self-cleans on the interior of the pipe as water flows through the lines. The water soluble flux has a narrower temperature range when heating, but it works with all the solders.
