In making a quick connection and hermetic seal for coupling low pressure systems of a type such as heat pipes and the like, a pre-installed fitting forming the sealing portion of a quick connection assembly is disposed in a depression formed in the sidewall of the low pressure chamber so that the chamber and the sealing portion of the connecting assembly can be fully processed together. The open end of a second system is coupled into the inserted sealing fitting by means of threads formed about a pipe plug device and carried by the tubular end portion of the second system. Sealant applied between the threads of the plug and fitting so that as the plug advances along the fitting a gas-tight seal will be obtained. The fitting includes a sealing membrane disposed across the inserted end thereof to be upset by advancing movement of the tubular end portion carried by the plug.
