A seal assembly configured to reduce fluid flow from an axially upstream side of the seal assembly to an axially downstream side of the seal assembly includes a primary seal and a secondary seal assembly disposed at an axially forward end of the primary seal. The secondary seal assembly includes a seal support and a secondary seal. The seal support includes a downstream axial face disposed axially proximate to and facing the primary seal, an upstream axial face opposite the downstream axial face, a body extending from the downstream axial face to the upstream axial face, a first leg extending radially inward from the body, a second leg extending radially inward from the body, and a mistake-proofing protrusion extending from the upstream axial face and in an axially upstream direction.
