Fittings for a Shotgun?

[Bee]

I'm trying to put together a shotgun condenser and I'm having some problem figuring out what parts to use. I'm not a plumber, so I don't know what is available or even what it would be called. The only things I know for sure are that I want a ball valve on the inlet side and that I want to hook up the male end of a garden hose on the inlet and the female end of a garden hose on the outlet.

So if you could help me out with a BOM I'd appreciate it.
