ABSTRACT:
A pressure gauge is disclosed which is generally suitable for use in connection with a fire extinguisher. The pressure responsive element is rotatably secured in position in the casing by an adjustable sleeve. The zero reference dial mark is provided on the casing, while remaining dial indicia may be on the viewing crystal. Both "off-pressure" and "on-pressure" alignment of the pointer and dial markings are enabled prior to sealing of the crystal to the casing. The seal between the crystal and the casing is ultrasonically formed and contains a weakened segment to enable release of excessive pressure within the casing.
