Metal hoses can withstand very cold and very hot temperatures, both in the surrounding environment and in the material going through the hose. They also resist vibration, abrasion, and many chemicals and will not allow gas to permeate through the hose wall. These hoses are sometimes used as an outer cover for other hoses to protect them from abrasion and overbending. They keep their shape and will not collapse when under a full vacuum. Interlocked metal hoses are made from a single strip of metal that is profiled and locked onto itself. The hoses' overlapping sections can slide back and forth to allow the hoses to flex. Corrugated metal hoses (also known as jacketed hoses) are used for conveying products that need to be heated or cooled during transfer. They have a flexible inner metal hose enclosed in a flexible metal outer hose (or jacket), and they have fittings on their ends that stop any material being conveyed through one of the hoses from moving into the other hose.

Corrugated metal hoses (also known as jacketed hoses) are ideal for conveying products that need to be heated or cooled during transfer. They are used in asphalt and hot-mix plants and the food, beverage, cosmetic, and pharmaceutical industries. These hoses consist of a flexible inner metal hose enclosed in a flexible metal outer hose (or jacket). Fittings on the ends of these hoses prevent any material that is being conveyed through the inner or outer hose from moving into the other hose. This allows the inner and outer hoses to be used to convey different materials. For example, steam or hot oils can be circulated through the outer hose to keep viscous material in the inner hose warm and fluid.

Interlocked metal hoses are made from a single strip of metal that is profiled and locked onto itself. They are also known as strip wound metal hoses. The hoses' overlapping, or interlocked, sections can slide back and forth to allow the hoses to flex. Rough bore interlocked metal hoses have a rough interior and are suitable for general purpose applications. Smoothbore interlocked metal hoses have a smooth, abrasion-resistant internal liner that helps prevent damage to products being conveyed in the hose and prevents material from building up inside the hose. The hoses come with fittings installed on the ends of the hoses and are ready to be connected to equipment.
