The seal assembly (100) includes an upper housing portion (109) having a first seal and a lower housing portion (110) including a second seal. The upper housing portion (109) is rotatably connectable to the lower housing portion (110). The surgical access device also includes a rotation prevention mechanism (1000) configured to prevent inadvertent relative rotation of, and disconnection of, the upper housing portion (109) and the lower housing portion (110). The rotation prevention mechanism (1000) is further configured to be selectively actuated by a user, such that, when actuated, the upper housing portion (109) is selectively rotatable relative to, and disconnectable from, the lower housing portion (110).1/1 1 100 204 214 1 0 FIG.
