A medical-gas panel connector system includes a frame assembly. The frame assembly includes a horizontal frame member, a vertical frame member connected to the horizontal frame member, and a ceiling integration assembly. The medical-gas panel connector system also includes a medical-gas outlet removably secured to at least one of the horizontal frame member and the vertical frame member via a bracket. In addition, a manifold is removably secured to the ceiling integration assembly, the manifold being at least partially disposed inside the medical-gas panel connector system, and a flexible gas line connects the manifold to the medical-gas outlet. The medical-gas panel connector can be reconfigured and rearranged within a modular wall system.
