A composite hose is a flexible, multi-layered hose designed for handling chemicals, fuels, and other industrial fluids. It is made from a combination of thermoplastics, films, and fabric layers reinforced with a metal wire helix for structural support. At JME we can make any composite hose assembly you need using United Flexible & Willcox brand composite hose.
Unlike rubber or stainless steel hoses, composite hoses provide superior chemical resistance, lightweight handling, and flexibility while maintaining high-pressure capability.
Structure of a Composite Hose
A typical composite hose consists of multiple layers:
-
Inner Liner: A chemically resistant thermoplastic (e.g., PTFE, Polypropylene, or Nylon) that prevents fluid contact with the reinforcing layers.
-
Reinforcement Layers: Woven fabric layers (e.g., polyester, polyamide) for strength and flexibility.
-
Outer Cover: A protective thermoplastic layer that shields against UV, abrasion, and weather.
-
Inner & Outer Helical Wire: Stainless steel, galvanized steel, or polypropylene-coated wires that spiral around the hose to provide strength and prevent collapse.
Advantages of Composite Hoses
Composite hoses offer a lightweight alternative to rubber or stainless steel hoses, making them easier to handle and install. Their extreme chemical compatibility allows them to safely transport acids, solvents, fuels, and other aggressive chemicals, outperforming metal hoses in demanding environments. With superior flexibility, even in larger diameters, these hoses provide greater ease of use compared to stainless steel hoses. Additionally, the metal wire helix reinforcement ensures durability under both high-pressure and vacuum applications. Composite hoses are designed for versatility and can be customized with specific linings and reinforcements to meet the unique requirements of various industrial applications.
Disadvantages of Composite Hoses
There are a few disadvantages of composite hoses that are worth considering. The first is that they are not as durable as stainless steel hoses. As a result, composite hoses can wear out faster in high-pressure or high-temperature environments. Typically, composite hoses have temperature limits around -40°F to 250°F (-40°C to 120°C). The last disadvantage to consider is that composite hoses require more maintenance than other hose types. Unlike stainless steel hoses, composite hoses can degrade over time due to environmental exposure.
Common Composite Hose Applications
- Petroleum Transfer – Used for loading and unloading fuels in refineries, terminals, and tank trucks.
- Chemical Processing – Handles acids, solvents, and corrosive chemicals in industrial plants.
- Marine & Dockside Use – Ideal for ship-to-shore fuel and chemical transfer.
- Cryogenic & LNG Handling – Some composite hoses are rated for low-temperature gases and cryogenic applications.
- Tank Truck & Railcar Loading – Frequently used in bulk liquid transfer for industrial transport.

Is a Composite Hose Right for You?
If you need a lightweight, highly flexible hose with superior chemical resistance for fuel, chemical, or industrial fluid handling, a composite hose is an excellent choice.
However, if you're dealing with high temperatures or need a long-lasting, high-pressure hose, stainless steel hoses may be a better option.
