Patent abstract
A pipe coupling for connecting pipes of the same or different diameters. The coupling has a barrel sleeve with clamping rings on each end. The clamping rings each carry nested seals. An inner portion of each nested seal may be removed so as to adapt the clamping ring to different pipe diameters. Each clamping ring is hinged, but becomes iron-bound upon tightening, so that each ring eventually bends as a unitary ring member.
