Abstract
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.
