Abstract
A flexible drum liner assembly having a fitting which mates with a specially cut hole in the lid of the drum. The fitting of a preferred embodiment of the present invention has a mouth with internal and external threads. A standard externally threaded bung hole cover fits in the mouth and mates with its external threads. A vertical slot is cut on either side of the mouth of the fitting interrupting the external threads. A circular bung hole with two opposed inwardly directed tabs is cut into the lid of the drum. The two tabs act as keys and fit into the keyways defined by the vertical slots on either side of the mouth of the fitting.
