A surgical access assembly includes a sleeve assembly, a base member, and a sealing assembly. The sleeve assembly includes a proximal ring, a distal ring, and a sleeve defining a passage therethrough. The base member includes an annular body including a coupling member. The annular body defines an opening in communication with the passage of the sleeve, and a circumferential groove configured to support the proximal ring of the sleeve assembly. The sealing assembly includes an annular frame and a seal dimensioned to cover the opening of the base member in a sealing relation. The coupling member of the base member releasably secures the sealing assembly to the base member. The annular frame of the sealing assembly is configured to be in registration with the annular body of the base member such that the proximal ring is interposed between the base member and the sealing assembly.
