The utility model discloses a flame-retardant hose assembly, which relates to the technical field of hoses and comprises a hose body, the hose body comprises a first hose, a hose connecting mechanism is arranged at the middle end of the hose body, and a bearing is fixedly mounted on the outer wall of the first hose. The flame-retardant layer is arranged on the outer wall of the cartilage wall to prevent the hose from being ignited, the flame-retardant layer is formed by fusing brominated polystyrene brominated organic flame retardant and colloid and has efficient flame retardance, the wear-resistant layer is formed by weaving nylon materials, the situation that the thickness of the hose body is reduced due to friction can be effectively prevented, and the service life of the hose is prolonged. The inner wall of the hose wall is coated with the sealing layer to prevent natural gas from slightly leaking out through the hose wall, and the sealing layer is formed by smearing sealing hot glue, so that the problems
