Abstract
A fire hydrant either of the 'wet' barrel type or the 'dry' barrel type having an improved hydrant nozzle construction. The barrel of the fire hydrant is provided with an internally threaded boss for receiving a replaceable externally threaded nozzle. Means for locking the nozzle to the boss of the barrel is provided so that the nozzle may not be removed by unauthorized personnel. Sealing means are provided between the nozzle and the boss of the barrel which can not lose its effectiveness due to cold flow and thus will not reduce the gripping effect of the nozzle to the barrel when the nozzle has been threaded therein with an initial torque.
