DIAPHRAGM SEAL ASSEMBLY Abstract of the Invention A diaphragm seal assembly for use with a fluid pressure responsive instrument includes an upper housing member having a first inner side. This inner side has a recessed surface de- fining a cavity and includes a passageway extending through the upper member for connection with the fluid pressure res- ponsive instrument. A lower housing member has a second inner side and a passageway extending through the lower housing member. A diaphragm is received in the cavity and is clamped between the upper and lower housing members. A clamping device is provided for securing the upper and lower housing members together. The improvement comprises a deformable lip structure extending from the first inner side for bending over the periphery of the diaphragm to sealingly secure the diaphragm to the upper housing member.
