What Is a Double Interlock Metallic Hose?

A double interlock metallic hose is built using interlocking metal strips formed into a flexible corrugated hose. It has two interlocking layers instead of one, which improves durability and prevents the hose from pulling apart under tension.

A Double Interlock Metallic Hose is a type of flexible metal conduit designed for applications that require strength, flexibility, and protection. It is commonly used in industrial, mechanical, automotive, and electrical systems to protect wires, convey gases, or handle low-pressure exhaust or ventilation.

Key Characteristics

1. Double-Layer Interlock Construction

• Made by tightly interlocking two layers of metal (often galvanized steel, stainless steel, or aluminum).

• Provides excellent mechanical strength compared with single-interlock designs.

• Prevents unraveling even under repeated bending.

2. High Flexibility

• The dual interlock structure allows the hose to bend easily while maintaining structural integrity.

• Suitable for routing in tight or curved spaces.

3. Crush and Abrasion Resistance

• More resistant to external damage due to the double-wall structure.

• Ideal for environments with vibration, abrasion, or mechanical stress.

4. Good Temperature and Corrosion Resistance

• Depending on the metal used, the hose can handle high temperatures and corrosive environments.

• Common in furnaces, exhaust systems, and chemical environments.
  

Common Applications

• Electrical cable protection in industrial machinery.

• Exhaust lines for engines, blowers, or ventilation systems.

• Protective casing for hydraulic or pneumatic lines.

• Car and motorcycle exhaust flex connectors.

• Transfer of low-pressure gases or fumes.

• Mechanical vibration absorption or isolation.
