Abstract
A plug assembly for plugging the flow hole of a core support barrel employs a pair of plug members which are initially collapsable to permit positioning between the core support barrel and the adjacent thermal shield. The plug assembly is activated to a projected plugged configuration by pneumatic or hydraulic pressure to provide a sealing engagement by a cooperative arrangement between circumferential locking barbs and a sealing lip.
