ABSTRACT:
A maximum pressure indicator for indicating maximum pressure of a fluid system employs a deformable disc which is bonded to a main plug. The plug has a cavity which is sealed by the disc so that a low pressure is maintained in the cavity. The indicator is inserted into an installation bore of a fluid system. The maximum pressure exerted against the disc is indicated by means of the deflection distance of the disc into the cavity. A helical coil spring assembly is employed to secure the indicator in fixed position within the installation bore.
