I believe that is a chrome coating over forged brass. You may want to make sure that that type of material doesn't leach anything. I use a stainless Ball valve but I went with a brass nipple and brass barb fitting (because I had them). Next time I may just go all brass to save money.
This is the first I've seen of the M/F valve, but I would say go for it if you don't mind it being forged brass...? Here is one that says its stainless, but at that price you could definitely afford a nipple instead:
