ABSTRACT:
An improved metal seal useful in conjunction with a pressure transducer or other pressure device or vessel. The pressure transducer comprises a pressure housing having an open end and having a housing wall. The housing wall preferably has internal threads and has a terminal end. The pressure transducer has a chamber defined by the housing wall of the pressure housing. The pressure transducer has a mating piece which engages the pressure housing, thereby enclosing the chamber. The mating piece has an externally threaded end for engaging the internal threads of the housing. The mating piece employing the invention has an overlap for engaging the terminal ends of the housing wall to prevent the housing wall from expanding and for forming a seal therewith. The overlap prevents the housing walls from expanding due to high pressures contained in the chamber of the pressure housing. Consequently, by using the overlap, pressure transducers having thin walls are able to withstand higher pressures.
