While desirable in general, Silver brazing is not really required for most plumbing fittings, unless they will be directly exposed to flame.

I mostly just use a somewhat higher temperature, low Silver content, slightly harder than regular soft solder, for most of my steam line plumbing needs.

I didn't realize that I could go with basically regular solder on piping. I thought over the years that almost everything needed to be silver soldered to be safe even though my Oatey 22002 solder has a melting point of 430 degrees which is hotter than you would normally find except, like you said, in contact with a flame or close to it. Thanks for the info - it'll help in the future.
