Just a quick FYI, I ran across a '4-way air line' splitter at Big Lots today. It was a milled piece of aluminum with 4 quick-release (female) couplings up the side and a brass plug at the end. It was just waiting to be taken apart, have ball/check valves installed for beer. I think it was selling for $6, but it might have been $4. McMaster seems to sell the same part for $15, without the quick-releases. I think all the connections were 1/4 NPT.
I realize that not every Big Lots sells everything, but it might be worth a look if you're nearby. I think the tool line was called Pro Shop or Shop Pro or something like that.
Thought all the cheap DIYers out there like me would like to know.
Make beer, not bombs.
(...and not bottle bombs either.)
