Flexible Corrugated Metal Hose Assemblies

Flexible Metal Hose Assemblies

Stainless Steel Flexible Corrugated Metal Hose Assemblies offers the solution where non-rigid connections for conveying liquids, gases and semi-solids are needed and offer a number of advantages including high strength, resistance to high or low temperature extremes, and corrosion resistance. It helps protect your equipment by absorbing vibrations and noise, connects misaligned rigid piping, connects moving parts of machinery or equipment, and is practical for hooking up frequently moved or dismantled equipment.

Metal hose is manufactured in three basic styles: Corrugated, Interlocked, and Square locked.

A wide range of sizes from 1/4" I.D. (inside diameter) to 24" I.D., with special sizes available upon special request.

The choice of metal hose is wide: bronze, carbon steel, stainless steel, monel, inconel, hastelloy with optional SS, or Bronze wire braid.

End fittings include male and female pipe threads, unions, flanges, flared tube fittings or other specially designed connectors.

*All assemblies are 100% tested. Special testing is available upon request: Hydrostatic, Mass Spectrometer, and Dye Penetration.

Special Hose Assemblies

Large diameter metal hose are frequently the only practical transfer hose for various chemicals, particularly if elevated temperatures are included.


With its ability to meet high demands for conveying hot and cold substances, this modern technology has the following major areas of application:

  • Electrical industry and mechanical engineering: as a protective hose for electrical cables or light conductors.
  • As a suction, conveying and coolant hose, e.g. when conveying and transporting liquid gas.
  • Automotive industry: as an exhaust gas hose that acts as a vibration decoupler in exhaust systems.
  • As a ventilation hose in technical building equipment.
  • Steel industry.
  • Measuring and control equipment.
  • Medical equipment.
  • Aviation and space travel.
  • Reactor technology.
  • Regenerative energies (solar heat, wind turbines, etc.)

Need even more flexibility?

Engineering can vary core widths, height and metal gauge to provide a custom hose based on your design requirements. Consult factory for details.

Jacketed Hose Assembly

Jacketed Assembly

When conveyants must be maintained at a specified temperature, steam jacketing is used frequently, often in lieu of electric tracing.

Guarded Hose Assembly

Guarded Assembly

Use of an external flexible armor protects metal hose from abuse due to rough handling, abrasion and bending below its limits. Often a rubber cover can accomplish this as well as armor if temperatures will permit.

Lined Hose Assembly

Lined Assembly

If high conveyant velocities are required, use of an internal flexible metal liner will prevent damage and reduce abrasion problems.
