A spray device is provided in which a spray stem section is secured within a passage of a spray device body. The stem section is readily removable to allow easy cleaning and also is normally made of materials which allow disposal after use of the stem section. In order to allow such use of plastics materials, in particular the stem section is associated with the passage such that seal elements isolate feed ports over a relatively broad communication band to gutter channels in the stem section. Normally a nozzle combination is secured within a jet such that this combination is also separately disposable. The nozzle combination is held within the spray stem section using a spray hood.
