ABSTRACT:
An improved trunk-line structure comprising a plurality of elongate beer lines and glycol lines made of flexible plastic tubing in parallel juxtaposition; an elongate sheath of high tensile strength, tear resistant, flexible plastic material is tightly engaged about and extending longitudinally of the assembly of beer and glycol lines and holds the lines in set position relative to each other; an elongate tube of soft, flexible, resilient, thermal insulating foam plastic material is engaged about and extending longitudinally of the sheath; and, a skin of inhervious, soft, flexible and resilient plastic material is positioned about and extending longitudinally of the tube, the plastic materials of which the parts of the trunk-line structure are made have low indexes of heat conductivity.
