An elastomer die plug for sealing or plugging a hole in an object, such as a coolant passage in an injection molding die. The plug includes a flexible, hollow cylindrical sleeve and a core member longitudinally interengageable into the sleeve. The core member is slightly larger than the bore of the sleeve and when drawn into the sleeve expands it to fill the hole and secure the plug. The plug may be used either internally as a diverting plug or externally as a sealing plug. The inserting tool is designed to position the plug in the hole as desired, and to interengage the core member into the sleeve. The plug is inserted into the hole with the sleeve and core member separate. Then the sleeve is supported in position and the core is interengaged into the sleeve.
