A wall duct assembly for a high pressure storage vessel, such as the carbonator tank of a beverage dispenser, includes a cylindrical ring formed in a wall area of the vessel having an inner surface defining an opening in the vessel, a wall duct bushing in the opening having a flange for sealingly engaging the interior wall of the vessel around the opening, an annular groove in the bushing opening towards the inner surface of the cylindrical ring and a sealing gasket in the groove. The wall duct bushing also has an annular bore through which electrical lines or other conduits may pass to the interior of the vessel. |
