Abstract The present invention relates to an improved metal- to-metal seal for a moving stem of a valve and includes a U-shaped ring having a base, an inner leg extending from the inner portion of the base and an outer leg extending from the outer portion of the base. The sealing surface of each leg is flattened and in its free position has a slight angle with respect to the axis of the seal. Each of the legs includes a support enlargement on its sealing side at a point toward the base from the sealing surface and preferably at the position of maximum deflection of the leg. The diameter of such supports is preselected so that in its free state they each are spaced a short distance from the walls against which their leg seals. The end of the outer leg is turned inwardly at an angle.
