Connector assemblies, fluid systems, and methods for making a connection

A connector assembly and a fluid system or device comprises a connector assembly which includes first and second fittings, each fitting having an aperture, and a stem disposed in the aperture of the first fitting. In various embodiments of the invention, the connector assembly may further comprise a socket cooperatively arranged with one of the first and second fittings, at least one resilient sealing member, a sealing layer joined to the socket or covering the resilient sealing member, and/or a deformable locking device. A method for making a connection includes mating a first fitting having an aperture and a second fitting having an aperture without fluid within the first and second fittings, establishing a fluid flowpath through the first and second fittings by advancing a stem having a head through the aperture of the first fitting into the aperture of the second fitting, and establishing fluid flow through the first and second fittings by opening a fluid blocking mechanism.
