Beschreibung
Zusammenfassung:	A method and assembly for reducing a radial gap between radially proximate components including a setting member having a first dimension that partially defines the radial gap, the setting member including a circumferential groove extending radially from the first dimension, and a first toroid having a second dimension, the setting member operatively arranged to engage with the first toroid, wherein increasingly engaging the setting member with the first toroid enables a boundary dimension of the assembly to be extended toward the radial gap for reducing the radial gap, the circumferential groove operatively arranged to catch the first toroid when the setting member is fully engaged with the first toroid.
