A tube system, in particular for a radiant panel heating or cooling, includes a first tube ( 10 ) and a sealing element ( 12 ), the sealing element ( 12 ) being injection molded into the tube ( 10 ). Further proposed is a tube ( 10 ) including a sealing element ( 12 ), in particular for radiant panel heating or cooling systems, producible by a two-component injection molding process, wherein at first the tube ( 10 ) made of a first plastic material is injection molded and subsequently the sealing element ( 12 ) made of a second plastic material is injection molded into the tube ( 10 ) or vice versa. Still further, a method of producing an assembly unit formed of a tube ( 10 ) and a sealing element ( 12 ) is provided, wherein in a first step the tube ( 10 ) made of a first plastic material is injection molded, with recesses ( 18 ) being provided for the sealing element ( 12 ), and in a second step the sealing element ( 12 ) made of a second plastic material is injection molded into the tube ( 10 ), so that the tube ( 10 ) and the sealing element ( 12 ) enter into a positive and frictional connection.
