A flow-through inflatable plug assembly inflatable in a pipeline. The flow-through inflatable plug assembly includes a flow-through fluid conduit and a separate "donut-shaped" inflatable member having an aperture defined therein. For operation, the flow-through fluid conduit is inserted into the aperture of the inflatable member. When the flow-through inflatable plug assembly is inflated in a pipeline, the inflatable member fills the void between the inner diameter of the pipeline and the outer diameter of the flow-through fluid conduit. Thus, the flow-through fluid conduit is sealingly captured in the aperture such that fluid flow in the pipeline is limited to passage through the flow-through fluid conduit.
