Abstract: Apparatus for forming a sealed joint between juxtaposed, axially aligned pipe ends includes a pair of annular flange members slidable in facing relation on the pipe ends and having tapered annular interior surfaces converging outwardly of a central axis for forming an annular recess about the pipe ends. A resilient annular sealing gasket generally compatibly shaped with the recess is provided for disposition therewithin about the pipe ends. The gasket has a pair of tapered annular exterior surfaces which converge outwardly when uncompressed at slightly greater respective angles than the tapered interior surfaces of the flange members for respective sealing engagement thereby. A bolt arrangement draws the flange members axially together to compressibly engage the tapered exterior gasket surfaces between the tapered interior flange surfaces, thereby to compress the gasket against and between the pipe ends to seal them.
