3/16" I.D. vinyl tubing is used for the beer hose in most applications where the distance between the keg and the faucet is less than 5’. The small I.D. (inside diameter) provides the correct restriction to the beer flow balancing against the pressure applied to the keg. This brewery approved hose will not rot, swell, or dry out and is unaffected by normal beer line cleaning chemicals. Also available priced by the foot, 50' coils, or 500' spools.
