A pipe joint is formed between two annular flanges at the end of pipe elements and includes a gasket in the form of an annular band having an outside diameter less than the bolts and an inside diameter equal to the diameter of the duct through the joint. The band is recessed on both surfaces from a shoulder spaced inwardly from the outer edge to the inner edge and these recessed portions are filling by annular bands of sealant material which is compressed in the finished joint.
