Yes these fittings would hold up for potable water us. They are approved for potable water systems, however you can not Stainless Steel and Brass materials together.
In reply to the dissimilar metals comment. Yes, it's true that Austenitic Stainless (e.g. ASTM A304) will *increase* the potential for corrosion when paired with brass; however, it is the slowest of the Galvanic reactions. Basically, *every* metal will corrode (rust) (at least a little) in the presence of stainless. This is because stainless offloads its electric potential to the nearest less-noble metal. Do a quick search on AISC Table 2-7 for more info. I am using stainless & PVC for a re-pipe of a residential pump room. The portion nearest the 1HP Grundfos stainless steel pump is all Merit stainless with Watts /Eastman /Pro Plumber brass bushings, gauges, & accessories as required. As long as you use 3-5 CW wraps of a high-quality PTFE tape (NOT pipe dope) and a decent set of wrenches, it will connect & disconnect well. I have not observed any brass corroding so far.
