A system for transferring molten metal (12) from a ladle (11) to a tundish (14) includes a nozzle (18) carried by the ladle (11) and having a bottom edge (30). A tube (19) has an upper edge (33) adapted to be positioned adjacent to the bottom edge (30) of the nozzle (18). The bottom edge (35) of the tube (19) is received in the tundish (14) and the passageway (32) in the tube (19) may receive a plug (39) to prevent slag (16) in the tundish (14) from entering the passageway (32). Either the bottom edge (30) of the nozzle (18) or the upper edge (33) of the tube (19) is generally spherical and engages a generally conical surface of the edge (30, 33) which is not spherical to form a seal between the nozzle (12) and the tube (19) irrespective of their precise alignment. The molten metal (12) may then pass from the ladle (11), through the nozzle (18), and through the tube (19) to displace the plug (39) and be received in the tundish (14).
