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.
