Buyer’s Guide to Metal Hose Assemblies

When performance, durability, and safety are a must, metal hose assemblies offer a level of reliability that rubber and composite hoses can’t offer. These hoses are built to endure high pressure, extreme temperatures, and corrosive environments. That’s why they are a staple in many industries including oil refining, petrochemical, bulk material handling, commercial food service, and much more.

This buyer’s guide explores how metal hose assemblies are constructed, the pros and cons of this hose type, and tips for understanding if this is the right hose type for your needs. 

Structure of a Metal Hose

Metal hose assemblies are intentionally designed for strength and performance. Their typical construction consists of a few key components:

  • Metal Core: At the heart of the hose is a flexible, metal core that allows for movement while maintaining strength under pressure and temperature stress.
  • Braid Reinforcement: For many metal hose assemblies there is a metal wire braid that reinforces the hose, prevents elongation, and contains internal pressure. 
  • Linear Material: Depending on the application, the hose may also feature a smooth or corrugated teflon liner, which offers chemical resistance and enhances flow.

The layered construction results in a host that is both flexible and maintains structural integrity, making it perfect for both static and dynamic systems. 

Advantages of a Metal Hose

Metal hose assemblies can excel in applications where traditional hoses may fall short. They are designed for extreme temperature resistance. The metal performs well in both high temperature environments (up to 1500°F) as well as extremely low temperatures. The metal is also resistant to corrosive fluids and gases, making it ideal for chemical plants and similar uses. Unlike rubber or composite hoses, metal does not allow gas fermentation, and its non-combustible nature makes it suitable for fire-safe applications. With proper installation, metal hose assemblies can outlast other hose types in even the most demanding environments.

Disadvantages of a Metal Hose

Despite all of the advantages,metal hose assemblies aren’t the perfect choice for every job and there are a few important things to consider. One disadvantage that you’ll notice immediately is that a metal hose is very heavy compared to other hose options. That extra weight can be a major drawback depending on where the hose will be used. Another thing to consider is that while flexible, metal hose assemblies are not as bendable as rubber hoses, especially in tight spaces or moving applications. The materials and fabrication process makes a metal hose more expensive upfront than many alternatives. Metal hose assemblies also require very precise installation to avoid kinking, over-bending, or mechanical failure due to stress on the tube. It’s important to balance the hose’s durability benefits against these few limitations when selecting your next hose. 

Common Metal Hose Applications

  • Chemical and Petrochemical Processing: For transferring aggressive acids and solvents at high pressures.
  • Cryogenics: metal hose assemblies have low-temperature tolerance, making it ideal for transporting liquid nitrogen, oxygen, or CO₂.
  • Utilities & Power Plants: Used in turbine systems, steam lines, and high-temperature coolant circuits.
  • Food & Beverage: Chosen for sanitary transfer applications requiring non-reactive, easy-to-clean surfaces.
  • Marine & Offshore: Excellent resistance to seawater corrosion and pressure surges on ships or oil platforms.
  • Industrial Application: Used for spacers and dampeners.

Is a Metal Hose Right for You?

If your application involves high temperatures, extreme pressure, or requires superior durability and corrosion resistance, a metal hose is often the right solution. It’s built to perform in challenging environments where other hose types may fall short. 

However, if your system demands lighter weight, greater flexibility, and operates within the pressure and temperature limits of rubber or composite hoses, those may be a better fit.
