An aerosol container valve which achieves a high standard of reliability comprises a gasket placed around the valve stem and held in position between the valve cup and the valve housing. The gasket is maintained compressed between the cup and the housing at a number of point locations spaced at a distance from each other and from the central bore traversed by the valve stem, the point locations being spaced at intervals on a circumference which is coaxial with the central bore.
