Corrugated Metal Hose

Our standard corrugated metal hose is made by forming annular corrugations into a thin wall welded tube. It is pressure tight and ideal for vibration, continuous flexing and when properly designed and installed, for thermal expansion and contraction. Helical hose is also available. We provide T-321 stainless steel, T-316 stainless steel, bronze, monel, and hasteloy corrugated hose. 

Technical Information

The selection of flexible metal hose for a particular application is influenced by six primary considerations:

  • Size
  • Temperature
  • Application
  • Media
  • Pressure
  • End Fittings
  • Delivery

To make the best choice for a specific application, consider all the relevant operating factors against the properties of the various types of flexible metal hoses.

Jacketed Metal Hose


The physical properties of any material vary with temperature. Working pressure, the type of media being conveyed and the nature of the application are what affect the limits for operating temperature. Flexible metal hose can be used for a wide range of temperatures given that the material is selected carefully. The temperature limit depends upon the hose type, metal alloy, end fittings and the method of fitting attachment choices.


Smooth bore PTFE hose is capable of carrying a wide range of difficult-to-handle media such as chemicals, steam, solvents, inks and dyes, paint, injectable materials and plastisols. It is used for a variety of applications such as sanitary transfer, bottle filling, gas analysis, extrusion presses and molding/adhesive conveying.

up to 30″. Standard jacket ports are 3000 lb. female NPT pipe couplings arranged 180° apart. Other port configurations, pressure ratings, end fittings and materials are available. 

Flextrol sets itself apart from competitors because of its success producing jacketed hoses from other materials such as fluoropolymer and rubber.

The temperature ratings for this kind of hose are quite broad: -100ºF to 450ºF. PTFE smooth bore hose offers improved vacuum ratings and damage resistance. It cleans easily with steam, detergent or caustic and can be autoclaved. Available in both true bore and nominal bore.
