A vent cover that permits venting of an enclosure and prevents the entry of contaminants into the enclosure is disclosed. The vent cover is integrally formed from an elastomeric material and has a cup-shaped main portion and an outwardly extending stem member which is received within an aperture in the enclosure. The stem member is slidingly movable within the enclosure causing the main portion of the vent cover to be in a non-contacting relationship with the enclosure when venting is required and to be in a contacting relationship with the enclosure when sealing of the enclosure from external contaminants is required.
