Sealing elements having sealing means extending therefrom are provided at each end of a column with at least one being movable in an axial direction and controlled by pressure generating means. The sealing members are shaped corresponding to the ends of the column to fit flush against the column and to provide a seal when actuated by the pressure generating means.
