BREWERY APPROVED BEER LINE: Our Kegman brewery approved beer line comes in two types: Vinyl Tubing and Polyethylene Barrier Tubing. Do not be fooled into using the cheap tubing found in home brew shops and department/hardware stores. They are not intended for beer and will cause foam and possible leach chemicals and off flavors into your beer.
Always use brewery approved beer line if you want to have foam free, fresh tasting beer. Many a great beer was spoiled by serving it through a plastic tube from the hardware or discount store. If you use the plain vinyl tubing in your beer tap system you will wind up with a foamy, off-tasting beer.

Kegs in Series - Just the Facts
Why Connect kegs in series?:
High volume dispensing: Eliminates the need to tap a new keg each time one empties. Beer switches and FOB's can also be used.
Long Remote Draw: Less beer is lost, especially important on long draw systems without FOBs. Requires keg usage of 3 kegs per week for profitability.
Changeover Convenience: For the best and freshest tasting beer, keep downtime to a minimum and make sure it is convenient to deliver kegs.
Kegs in Series Definitions
Un-tapping order Faucet keg first then work backward to gas keg.
Kegs in Series Requirements
Kegs are connected using ⅜" I.D. beer lines, usually 4 to 6 feet in length, and using ⅜" tailpieces, not gas nipples. Series kegs are connected starting with the beer outlet of the Tap from the upstream keg, to the CO2 inlet of the Tap for the next downstream keg in the series. The C02 inlet should be a 5/16" hose barb connection. The check valve is removed from each Tap of the intermediate and faucet kegs. The check valve should be left in the gas keg Tap. It is important to clean any excess and dirty lubricant off the Tap, since beer will flow on the outside of the probe and through the C02 nipple to the jumper line. The entire series of kegs should be emptied at least once every 7 days to maintain draft beer quality. Therefore, the number of kegs placed in series should not exceed the volume of beer dispensed in one week. 10 kegs maximum should be allowed in series.
Rotation of Kegs Connected in Series: Always connect the partially filled keg as the gas keg so the beer can flow properly through the kegs in series. See diagram.... The oldest date code keg should always be the faucet keg. All kegs must empty every 7 to 14 days to insure freshness.
