The seal system includes an attachment or coupling device having a generally cylindrical, downwardly extending lower insert section. The lower insert section includes an annular bottom wall in which is formed an annular recess opened downwardly. An upper head section is formed at the upper end of the insert section and includes a radially extending flange. The insert section is dimensioned to fit in and be received by the hollow of the boss above the shoulder. The seal system also includes a resilient O-ring for disposition in the recess of the insert section of the coupling device to protrude from the recess a sufficient distance to contact and seal against the lip section of the liner resting on the shoulder of the boss hollow, when the insert section is fitted into the hollow.
