Abstract: A keg tapping apparatus includes a keg unit secured within the neck of a keg by a retainer and a tavern unit coupled to the keg unit by the retainer. An operating handle opens valves associated with the keg unit to establish fluid communication between the keg and fluid inlet and outlet fittings on the tavern unit. The retainer has a body which includes a generally cylindrical bore and notches which communicate with the bore. Complementary inserts received within the notches are integrally attached to the body and define coupling lugs which project into the bore for coupling connection with the tavern unit. The inserts are made from a harder material than the body.

Abstract: A universal tavern unit for a keg tapping device comprises a basic tavern unit for connection to a keg unit permanently or semi-permanently connected to a keg. The basic tavern unit is adapted to cooperate with the keg unit to provide inlet and outlet passageways which commuicate with the interior of the keg for the introduction of gas under pressure into the keg and the discharge of beer or other liquid therefrom. The universal tavern unit further includes a pressure relief check valve adaptor assembly for connection to the basic tavern unit to adapt it to the requirements of an associated beer or liquid distribution system.
