<p>There is provided a flexible composite hose constructed such that a plastics inner tube is covered with an outer tube of heat-shrinkable material, with the inner tube being compressed by the shrinkage force of the outer tube. It is produced by covering an inner tube with an outer tube having a slightly larger inside diameter than the outside diameter of the inner tube, and then heating the tube assembly at a proper temperature to effect heat shrinkage. It has good chemical resistance and pressure resistance.</p> |
