Abstract
A metal airtight seal with bidirectional face, self-energizable by pressure, with axisymmetric or non-axisymmetric configuration, has teeth guided at acute angles, both towards the center of the ring and outside, radially. This geometry may provide the airtight seal the characteristic of being self-energizable by fluid pressure and providing bidirectional sealing, both to the internal pressure and to the external pressure. Furthermore, second element of the airtight seal has a course stopper, to limit the deformation of said metal airtight seal. First and third elements of the airtight seal provide the airtight seal high resistance against internal and external pressure, due to the control of radial slacks.
