Method for manufacturing fuel transporting hose

摘要

A method for manufacturing a fuel transporting hose (1) which is low in manufacturing costs and is superior in characteristics, including insertability, sealability and pull-out resistance. The method includes the steps of extrusion-molding an unvulcanized hose having fluoro rubber as an inner layer (2) without using a mandrel, vulcanizing the unvulcanized hose so as to form a fuel transporting hose having a fluoro rubber inner layer (2), and forming a fluorine-modified silicone lubricating layer (6) on the inner peripheral surface of the fluoro rubber inner layer (2). <IMAGE>
