Hose for vehicles air conditioning system, has swivel joint providing connection between rigid and flexible parts, and satisfying rotation function, sealing function, and locking or axial hold function between parts

摘要

The hose has a rigid part (1) with a metallic tubular component, and a flexible part (3) with an undulating metal. A swivel joint (15) providing watertight connection between the parts satisfies a rotation function, a sealing function, and a locking or axial hold function between the parts. The joint is positioned or mounted between two rigid metallic tubular ferrules (15a, 15b).
