A B S T R A C T Novel system for providing lubricity to the surface of a nasogastric intubation device, which system comprises a substantially homogeneous mixture consisting essentially of: (1) an effective amount of an unsaturated higher fatty acid having at least 16 carbon atoms; and (2) a polymer compatible therewith. The mixture may be coated on the surface of the portion of the length of the tube assembly to be lubricated or, alternatively, the acid may be contained in the polymer mix employed in the manufacture of the tube assembly. When the acid-containing surface is contacted with an aqueous alkaline solution prior to intubation, the acid is converted to the corresponding lubricious soap.
