A surgical portal apparatus includes a portal housing, a portal member, and an elongated seal mounted within the portal housing. The portal housing defines a housing opening for reception of a surgical object and the portal member extends from the portal housing. The elongated seal includes an outer wall segment and an inner seal segment. The outer wall segment has first and second ends that are mechanically coupled to the portal housing. The inner seal segment is disposed within the outer wall segment and depends radially inwardly relative to the longitudinal axis. The inner seal segment has inner surfaces that define a seal passage and is adapted to establish a substantial sealed relation with the surgical object. The outer wall segment includes a flexible material to permit deflection of the outer wall segment and corresponding movement of the inner seal segment in at least a radial direction with respect to the longitudinal axis.
