An apparatus for the continuous casting of metallic strand from a melt has a fluid-cooled coolerbody surrounding a casting die, and resilient O-ring seals which surround the upper and lower ends of the coolerbody to contain the cooling fluid within a distribution conduit. Extensions of the cooling fluid distribution conduit are formed within the coolerbody between the O-rings and the heat-dissipating strand, as protective thermal barriers to limit the temperature rise experienced by the O-rings. An annular shield also is disposed intermediate the upper O-ring and the strand to form two air gaps which enhance the thermal barrier effect.
