Description
Power Hydraulic manufactures the High Temperature Metal Hose Assembly for industrial systems that require flexible fluid transfer under elevated temperatures, vibration, movement, thermal expansion, or demanding operating conditions.
Our metal hose assemblies combine a corrugated stainless steel hose, optional stainless steel braid, and customized end fittings to provide a flexible connection between pipes, valves, pumps, compressors, heat-processing equipment, and other industrial systems.
Customers can send us:
- Technical drawings
- Hose dimensions
- Existing samples
- End connection requirements
- Operating temperature
- Working pressure
- Fluid medium
- Installation movement
- Required assembly length
Our team reviews these conditions before recommending the hose structure, material, braid configuration, and end connections.
With a manufacturing background in metal hose products, hydraulic components, CNC-machined fittings, and customized fluid connections, Power Hydraulic focuses on practical hose assemblies that match the customer’s actual system rather than supplying only standard catalog products.

What Is a High Temperature Metal Hose Assembly?
A High Temperature Metal Hose Assembly uses a flexible metallic hose to transfer liquids, gases, steam, or other process media where conventional rubber or polymer hoses may not suit the operating temperature or working environment.
A typical assembly contains:
- Corrugated metal hose
- Stainless steel wire braid
- Braid collars
- End fittings
- Welded connections
- Optional protective components
The corrugated hose provides flexibility, while the external braid helps control elongation and supports the hose under internal pressure.
Together, these components create a flexible connection that can accommodate:
- Thermal expansion
- Mechanical vibration
- Pipe misalignment
- Equipment movement
- Repeated flexing within the designed range
Industrial users often select metal hose assemblies when they require both temperature resistance and mechanical flexibility.

Why Use Metal Hose for High-Temperature Applications?
High-temperature piping systems can create significant challenges for rigid connections.
As equipment heats and cools, pipes and components expand and contract. Pumps, compressors, engines, and processing machinery can also generate vibration.
A flexible metal hose assembly can help manage these movements while maintaining a sealed fluid connection.
Customers commonly use high-temperature metal hoses when:
- Rubber hoses cannot tolerate the required temperature.
- Equipment generates continuous vibration.
- Thermal expansion creates stress in rigid piping.
- The system requires a flexible connection near a pump or compressor.
- Installation space requires a bendable connection.
- Existing metal hose assemblies need replacement.
- The application requires corrosion-resistant metallic materials.
- OEM equipment uses a non-standard hose length or fitting configuration.
Corrugated Stainless Steel Hose Construction
The corrugated metal hose forms the flexible core of the assembly.
Manufacturers form thin-wall metallic tubing into a corrugated profile that allows controlled bending and movement.
The geometry of the corrugation affects:
- Flexibility
- Bend performance
- Pressure capability
- Fatigue life
- Movement characteristics
For this reason, engineers should select the hose according to the actual application rather than diameter alone.
Power Hydraulic evaluates the hose size, assembly length, operating conditions, and required movement before production.

Stainless Steel Braided Metal Hose
Many high-temperature hose assemblies include one or more layers of stainless steel wire braid around the corrugated hose.
The braid performs several important functions.
It helps:
- Restrain hose elongation
- Support internal pressure
- Protect the corrugated hose
- Improve mechanical stability
- Maintain the intended hose geometry
Depending on the application, a hose assembly may use:
- Unbraided corrugated hose
- Single-braided metal hose
- Multi-braid configurations for specific requirements
The correct braid structure depends on the pressure, temperature, hose size, movement, and installation conditions.
Materials for High Temperature Metal Hose Assemblies
Material selection plays a major role in temperature resistance, corrosion resistance, fatigue life, and compatibility with the transported medium.
Stainless Steel
Stainless steel remains one of the most common materials for industrial flexible metal hoses.
Depending on the project specification, commonly considered stainless steel grades may include:
- 304 stainless steel
- 304L stainless steel
- 316 stainless steel
- 316L stainless steel
316-series stainless steel can provide additional corrosion resistance in suitable chemical, marine, and process environments.
The final material choice should always consider:
- Operating temperature
- Fluid or gas composition
- External environment
- Corrosion risk
- Pressure
- Required service life
Custom End Connections
The hose itself represents only one part of a reliable metal hose assembly.
The end connections determine how the hose integrates with the customer’s equipment and piping system.
Power Hydraulic can evaluate customized assemblies using different connection designs, including:
- Threaded fittings
- Male threaded ends
- Female threaded ends
- Flanges
- Weld ends
- Tube ends
- Pipe ends
- Hydraulic-style fittings
- Custom CNC-machined connectors
- OEM replacement fittings
Customers can provide drawings or samples when standard end fittings cannot meet the installation requirements.
CNC Machined Fittings for Metal Hose Assemblies
Because Power Hydraulic also supports custom CNC machining, we can evaluate projects that require non-standard hose end connections.
Custom-machined fittings may include:
- Special thread combinations
- Non-standard hex dimensions
- Extended connection lengths
- Custom sealing surfaces
- Special flange geometry
- Compact installation designs
- Replacement OEM connectors
This capability helps customers reduce the number of separate suppliers involved in a custom metal hose project.
It also supports equipment manufacturers that need a hose assembly designed around their existing machine rather than around a standard fitting catalog.
Welding and Hose Assembly
The connection between the corrugated hose and the end fitting plays an important role in assembly integrity.
During manufacturing, the production process must control:
- Hose alignment
- Braid positioning
- Fitting alignment
- Weld location
- Heat input
- Surface condition
The exact manufacturing method depends on the hose structure and fitting design.
After assembly, our team checks critical dimensions and connection quality according to the confirmed project requirements.

High Temperature Metal Hose Applications
High-temperature flexible metal hose assemblies serve many industrial sectors.
Steam and Thermal Systems
Metal hoses can provide flexible connections in systems involving:
- Steam lines
- Heating equipment
- Thermal process machinery
- Heat exchangers

The customer should always provide the actual operating temperature and pressure before hose selection.
Industrial Exhaust Systems
Flexible metal hoses can accommodate vibration and thermal movement in:
- Exhaust piping
- Engine systems
- Generator equipment
- Industrial machinery
- Gas handling systems
Chemical and Process Equipment
Stainless steel metal hose assemblies suit many process applications that require flexible metallic connections.
Typical equipment may include:
- Chemical processing machinery
- Fluid transfer systems
- Pumps
- Reactors
- Processing skids
Material compatibility with the process medium remains essential.
Pumps and Compressors
Rotating equipment can transmit vibration into connected pipework.
A properly selected flexible metal hose can help isolate part of this movement between:
