Review on Oatey Company 30374 1 7 Flux by Jimmy Koroye

This is what you need for plumbing brazing especially if you are new to the business. The flux contains silver particles that can help fill in small gaps if you are not making a perfect solder. Used this several times with zero leaks, zero problems. The only thing that confuses me is that the material is a bit stiff right out of the can until it warms up a bit. Applying with a brush can be tricky due to the density, but I think it's worth the small compromise.
