ABSTRACT:
A resilient flexible pipe coupling for interconnecting two pipes of different diameters in a pressure tight manner comprises a tubular metal casing formed with a longitudinal gap and a tensioning screw device for reducing the width of the gap to tighten the coupling around the adjacent ends of the two pipes. A sealing sleeve of resilient flexible material is arranged within the casing. The sleeve has radially inwardly projecting sealing lips formed on both of its free end. The sealing lips have different radial thicknesses so as to compensate for the difference in diameters of the pipes.
