Abstract: A compliant jumper tube fitting assembly may comprise an outer housing comprising a first annular cylindrical structure including a first opening defined by a base wall, and an inner housing comprising a second annular cylindrical structure including a second opening defined by an annular wall, wherein the inner housing is configured to generate a seal between an inner diameter wall of the outer housing and an outer diameter wall of the inner housing in response to inserting the inner housing into a mouth end of the outer housing, wherein the inner housing is configured to receive an end fitting and generate a seal between an inner diameter wall of the inner housing in response to inserting the end fitting into the inner housing.

Abstract: An assembly is provided for a turbine engine. This turbine engine assembly includes a tower shaft rotatable about an axis, an engine component rotatable with the tower shaft about the axis, and a seal assembly. The engine component extends axially along the axis to an end surface. The seal assembly includes a carbon seal element, where the carbon seal element circumscribes the tower shaft and axially engages the end surface.
