Abstract
A system for conveying fluids, particularly molten polymer in an extrusion melt train. The system has a first element having a first fluid passage. The first element also has a first interface surface thereon, such that the first interface surface is non-orthogonal to the axis of the first fluid passage. The first element also has a first interlocking feature. The system also has a second element having a second fluid passage. The second element also has a second interface surface thereon, such that the second interface surface is non-orthogonal to the axis of the second fluid passage. The second element also has a second interlocking feature. In use, the first element and the second element are placed in a linking position adjacent each other such that the first fluid passage is in fluid communication with the second fluid passage.
