ABSTRACT:
A fluid coupling, e.g., a subsea coupling, includes male and female parts which can be coupled together. The female part includes four passages normally closed by a slidable gate. The male part includes four passages normally closed by a closure slide. When the male and female parts are coupled together, the gate is pushed aside by the gate part and becomes temporarily joined thereto, and the closure slide is pushed aside by the female part and is temporarily joined thereto. When the male and female parts are uncoupled, the gate and closure slide are moved back to their passage-closing positions. A metal sealing member for the passages includes annular thick and thin lips. The thin lip provides flexibility, and the thick lip engages a relatively movable part.
