A bung member (25) is insertable into the open end of the enclosure to seal the enclosure. The member defines a channel (27) and a spreader element (28) is insertable into the channel. The spreader element is formed to cause the bung member to expand upon insertion of the spreader to seal the enclosure against moisture and contaminants.
