Abstract
A method of fastening a first shell to a second shell to form a housing. The first shell which has a radial wall with a projection adjacent its peripheral surface is positioned in a fixture. A bead on a diaphragm assembly is located in a groove in the projection. The opened end of an annular wall on the second shell is placed around the bead and peripheral surface. The second shell is moved toward the first shell until the peripheral surface contacts a stop on the second shell. Thereafter, the opened end of the second shell is crimped into engagement with the radial wall to hold the peripheral surface in engagement with the stop. The fixture is rotated while a tool is brought into contact with the annular wall. The tool deforms the wall by creating a rib that radially compresses the bead into the groove and seals the housing.
