Stainless steel ball lock quick disconnect with flow control (Smalley DE7)

I have four of these, three still boxed! For keen homebrewers

Adjust the flow rate of liquid at the disconnect.

Perfect for balancing a corny keg system with multiple kegs of different styles of beer all using the same regulator.

Also great for connecting a tap directly to the liquid post of the keg (not necessary if you have a flow control tap) using an MFL tap shank adapter
