GrowlerWerks uKeg™ ball-lock fej

The uKeg™ ball lock cap adapts the uKeg™ to existing CO2 systems through a standard ball lock interface, allowing you to use your own CO2 supply to power the uKeg™. Great for force carbonating. Features: ball lock interface seals when disconnected pressure relief valve set to 20 psi fits both the uKeg™ 64 and uKeg™ 128 Note: For the uKeg™ to work properly with the ball lock cap, it must be connected to an external, regulated CO2 source. The source may be disconnected or turned off for storage and transport, but needs to be on for proper dispensing.
