Abstract

A sealing element that includes a hollow body of metallic material and first and second male sealing members formed at a respective end of the body. The respective male sealing member has an external spherical contact surface designed for mating with a corresponding internal conical contact surface of a female sealing member so as to form a fluid-tight seal between the male sealing member and the female sealing member when their contact surfaces are pressed against each other. Also, a coupling device and a valve device provided with the sealing element.
