Abstract: An interface arrangement includes two annular components that extend along an axis and are in contact with one another and a third component that is positioned radially inward from at least one of the two components. There is an anti-rotation feature on one of the three components that engages an anti-rotation feature on an annular seal member. The seal member is in contact with the first two components and is positioned between the third component and at least one of the first two components.
