The body of the super flexible spiral hose is a tubular shell with a spiral arrangement of bellows. There is a spiral angle between the ripples, and all ripples are connected by a helix. The super flexible spiral hose has a diameter of 15–400 mm, and a wall thicknesses of 0.15–0.6 mm. It is suitable for assembly into medium and small diameter metal hoses (where the metal hose is assembled with associated fittings and couplings to form a complete unit for ease of installation and use).
