I'm needing hoses to run to and from my barbed ball-lock quick disconnect on my cornelius keg.

  • Which diameter should I be getting?
  • Do I need reinforced hoses?


  • 1/4" (6mm) Inner Diameter.
  • 3/16" (5mm) Inner Diameter, with boiling water to soften and stretch.
  • Reinforced is not required.
  • 1
    For dispensing, 3/16 is preferred for short runs, as it has higher internal resistance. That is, you can use a shorter line and achieve the same drop in pressure as a longer length of 1/4 line would provide. Jan 9 '14 at 15:19
  • Ah, this has some important balance between serving pressure of the beer vs carbonation correct? Can you help me find a suitable Q&A to link with ? Jan 9 '14 at 16:11

I believe it is 1/4 Inch (6mm) Inside Diameter pipe, but you should also be able to force a flexible 3/16 (5mm) ID pipe over it.

There is no need for reinforced hose if you are using proper beer and gas line.
