ABSTRACT:
The testing instrument for pipes or other cavities to be tested as to tightness includes an at least partially conical rubber plug, at each of the opposite ends of which supporting plates are provided. A pipe which extends through the rubber plug is rigidly connected to the supporting plate at the end having a smaller diameter and is passed through the other supporting plate so as to be movable. A protruding section of the pipe is provided with a thread and a pedestal is screwed to the threaded section. Two eccentric levers are tiltably mounted to the pedestal diametrically opposite each other and rest on the supporting plate at the larger diameter of the rubber plug. A crown member is provided on the pipe, to which a CO testing apparatus is connected. Variations of the rubber plug are disclosed, with which various openings which are difficult to seal can be securely sealed.
