Abstract
A self-sealing end fitting includes a valve, an adaptor, and a connector. The valve may define a longitudinal axis and may include a first end portion, a second end portion, a flange disposed therebetween, and a central bore. The adaptor may have a first end portion surrounding at least the second end portion of the valve, and the connector may surround at least the first end portion of the valve. A portion of the connector, a portion of the flange, and a portion of the first end portion of the adaptor may define a pocket. The valve may be configured to move axially relative to the adaptor. In embodiments, a sealing surface of the flange may contact a corresponding sealing surface of the first end portion of the adaptor to form a first seal within the pocket, and the first seal may comprise a metal-to-metal seal.
