FIELD: machine building.
SUBSTANCE: sealing gasket for tightening of flanged joint comprises annular sealing element and support facility for fixation of a sealing element. Annular sealing element is made in the form of flat rigid ring, at end surfaces of which there are elastic sealing rings installed, diametre of which is less than diametre of flat rigid ring. Difference in diametres of flat rigid ring and elastic sealing rings, and also their concentric location results in creation of annular round edge at annular sealing element. Support facility consists of two annular parts that have end surfaces joined to each other and annular surfaces that diverge from end surfaces radially inside, which together create a cavity for round annular edge of annular sealing element.
EFFECT: invention provides for reliability of sealing.
