<p>A spray nozzle assembly has a main nozzle body defining a socket having a part-spherical surface. A nozzle ball (16) is mounted within the nozzle socket and, in known manner a collar or the like is used to secure the ball in position. To provide an adequate seal between the nozzle ball (16) and the nozzle body, a sealing lip (50) is provided on the nozzle ball (16). This lip (50) extends radially outwardly beyond the nozzle ball. The lip can be in the form of a cone tangential with the spherical surface (52). This sealing configuration can be used for other purposes, and is generally applicable to providing a connection between two fluid conduits, which are required to meet at an angle that is adjustable.</p> |
