The filler comes with a standard length of 2.5m ID 3.2mm (1/8") / OD 6.4mm (1/4") beverage hose to connect between the keg and the filler. The length is to provide adequate and even pressure drop in the hose to avoid foaming. The flowrate of the standard hose is 1.2 liter/minute @1 bar keg pressure.
There's also a ID 2.5mm / OD 4mm hose included. Use this for the foamy beers.
