Abstract
An assembly for an aircraft powerplant includes a first component, a second component, an annular seal element and a third component. The first component includes a first land surface which extends axially along and circumferentially about an axis. The second component includes a second land surface radially opposite the first land surface. The second land surface extends axially along and circumferentially about the axis. The annular seal element extends radially between a first side and a second side. The annular seal element includes a base, a plurality of ribs and a groove. The base includes a seal element surface disposed at the first side that radially engages the first land surface. The ribs are disposed at the second side. Each rib projects out from the base and radially engages the second land surface. The groove projects partially axially into the base. The third component projects axially into the groove.
