Ultrasonic transducers which are constructed to have an outer shell surrounding a portion of the acoustic transformer of the transducer to serve as a vibration damper and also as part of the transducer structure. The shell is attached at a region near the node of the transformer to control the quantity of energy transmitted thereto. In many of the embodiments, the outer shell is attached without the necessity of a resilient support. The transducer is also constituted to accept a housing and form a sealing relationship therewith to fluid, in some embodiments a portion of the sealing means being located on the outer shell, and in other embodiments on another portion of the transformer.
