ABSTRACT:
A sealing element located on corresponding openings of adjacent components which are rigid with respect to one another. The openings of the component terminate in sealing surfaces which are located opposite to one another and spaced from one another. A sealing ring, radially outwardly opened, is provided with a trapezoidal internal contour. The sealing ring is located between the sealing surfaces of the two components and cooperates with such components. The sealing ring is centered on a centering bead on an inside diameter of one of the components and a spreading element is located between inner leg surfaces of the trapezoidal internal contour of the ring for spreading the outer surfaces of the ring against the sealing surfaces of the component.
