Abstract: A universal cap seal for fifty-five gallon drums designed to fit over bung flanges and rims in drums of varying size and varying height. The universal cap seal comprises a body having a flat upper surface and an internal surface. The flat upper surface of the body includes a channel that holds a tamper evident lifting band. The lifting band has a lifting tab that enables the user to remove the cap seal from the flange. A sidewall extends from the flat upper surface. A shield extends downwardly from the sidewall and includes a plurality of individual pivotal segments separated by a plurality of slits. The internal surface of the body includes at least two downwardly extending internal snap elements that frictionally engage an outer portion of the flange.
