1. A pre-sintered preform (PSP) sealing device for a metered passage of a turbine component, the PSP sealing device comprising:
a sealing body made of a pre-sintered preform (PSP) material, the sealing body having an opening defined therethrough having a first cross-sectional area, and the sealing body having an outer dimension configured to position the sealing body in the metered passage of the turbine component; and
a hollow member fixed within the opening defined through the sealing body, the hollow member having a second cross-sectional area smaller than the first cross-sectional area of the opening,
wherein the hollow member is made of a material having a melt temperature higher than a melt temperature of the PSP material.
