Abstract
A coupling and metal seal are disclosed, primarily for use in undersea hydraulic applications. The female member of the coupling is of three-piece construction. The main body portion accepts a cylindrical retainer which is held captive within the body by means of a spring clip or snap ring. The metal seal is generally ring-shaped and is positioned within the body and held captive by the retainer and clip. The male member, or probe, of the coupling fits within the retainer and body and protrudes through the ring of the metal seal. The seal engages the circumference of the probe and, when the coupling is pressurized, the seal is urged against the probe circumference and against the interior wall of the body, effectuating a fluid seal within the coupling. The metal seal is not irrevocably deformed in use and may be used repeatedly.
