Annular seal

Abstract

A annular gasket defining a circumferential extension trajectory lying on a main plane, a section plane normal to the extension trajectory and to the main plane, and sagittal plane tangent to the extension trajectory and normal to the main plane, and including a profile defining on the section plane an X shape divided by the sagittal plane in a first side and a second side, in which the first side is divided from the main plane into a first lip suitable for being inserted in a seat and a second lip, the second side is divided by the main plane into a third lip and a fourth lip, and the first lip is rounded and normally extends to the sagittal plane less than the second lip, and the second lip defines a free end including an edge.
