<p>The sealing element comprises an annular active portion of elastomer material adapted to be compressed radially between the outer surface of a male end and the wall of a cylindrical recess in a socket in which the male end extends and means for anchoring the sealing element in the socket, the active portion comprising an outer annular face, an inner annular face and an end face having, when the sealing element is at rest, a minimum inside diameter exceeding the outside diameter of the male end and a maximum outside diameter exceeding said minimum inside diameter by an amount exceeding the radial clearance between the recess and the male end. The end face is connected to each one of the annular faces of the active portion by a circular edge, and, when the sealing element is in the free state, in axial section, the rise or dip of the arc generating the end face is at the most equal to 1/5th of the length of the associated chord.</p> |
