Claim:
1. An aft clamp ring for a gas turbine engine, the aft clamp ring comprising: a body with an annular shape revolved about an axis, the body including an outer end, an inner end located radially inward and distal to the outer end, an aft surface facing in a first axial direction, and a forward surface facing in a second axial direction opposite the first axial direction; a first protrusion proximate the inner end extending from the body in the first axial direction; a second protrusion extending from the first protrusion in the first axial direction, the second protrusion being radially narrower than the first protrusion; a forward sealing portion extending in the second axial direction from the body, the forward sealing portion including a forward sealing face proximate the outer end facing in the second axial direction and located radially outward and axially forward of the forward surface, the forward sealing face being a first annular surface; an aft sealing portion including an aft sealing face adjacent the outer end facing in the first axial direction and located radially outward of the aft surface, the aft sealing face being a second annular surface; and an aft cutback separating the aft sealing face from the aft surface.
