Abstract

A tube extends through a wall of a vessel and is adapted to carry an ultraviolet emitter for use with a photochemical reaction vessel. An end of the tube disposed outside of the vessel is mounted within a support which forms a ball joint for that end of the tube. That joint allows the tube to pivot slightly in response to forces acting on the portion of the tube disposed within the vessel, thereby resisting any breaking or bending of the tube which might otherwise occur. A lip seal is disposed around the tube at a location intermediate the ball joint and the vessel to prevent the escape of fluids from the vessel past the tube.
