    • An apparatus includes a body member and a ring member. The body member has a through passageway, and the body member includes an outer engagement surface. The ring member has a contracted state and an expanded state, and the ring member includes an inner engagement surface and an outer surface. The seal member is adapted to axially move with respect to the body member in response to the application of an axial force such that the outer engagement surface of the body member physically engages the inner engagement surface of the ring member to radially expand the ring member to transition the ring member to the expanded state and cause the outer surface of the ring member to contact an inner wall of a tubing string. The physical engagement of the inner engagement surface of the ring member with the outer engagement surface of the body member forms a seal between the ring member and the body member. The contact of the outer surface of the ring member with the tubing string forms a seal between the ring member and the tubing string and secures the ring member to the tubing string. The inner engagement surface and the outer engagement surface are adapted to physically interact to retain the ring member in the expanded state when the axial force is removed.
