Japanese Patent JP2016041960

A

PROBLEM TO BE SOLVED: To provide a hose with a joint capable of preventing the joint from coming off, and excellent in pressure resistance and durability.SOLUTION: A hose with a joint includes the hose and the joint attached to at least one end of the hose, and the joint has a nozzle inserted into at least an inner side of the end of the hose. The innermost side of the hose is made of polyolefin-based resin, a tapered annular protrusion is formed on an outer peripheral surface of the nozzle at a portion inserted into the hose, and a corner R of an edge in the tapered annular protrusion is within a range of 0.03-0.20 mm. A flat portion having a same outside diameter is formed on the outer peripheral surface of the nozzle at the portion inserted into the hose, and the outside diameter of the flat portion is equal to an outside diameter of the tapered annular protrusion, and the tapered annular protrusion is formed on an insertion end side of the flat portion.SELECTED DRAWING: Figure 1
