Bomber,
Check out page 7 --- post #70 ... Close up pics of packages with numbers.
I got it all at Lowes, here they have a sprinkler section on the same isle as plumbing. All I had to do while gettting all my elbows and T's, was turn around.
The regulator is a 25 psi, they also have a 50 psi, I think it says on package,, to use 25 if using push on hoses. You also need an adaptor, you can see it all in the pic.
