Ok... I wan to DIY this thing. I have a faucet, and ball lock liquid-line connector. What is that piece in the middle? I'm not seeing what is there. Anyone else built one of these?
A faucet to quick disconnect adapter. Try some of the vendors on this list also, kegconnection, kegcowboy, etc.http://morebeer.com/view_product/18286/102290/QD_Faucet_Adapter
