  • Ask our experts

    Steam has a destructive impact. Therefore, it is very important to choose the right rubber steam hose for a specific application. Our experts, with the necessary know-how and experience at hand, are always ready to assist you in matching the right hose to specific working conditions.

  • Discover the highest quality

    Rubber steam hoses are made of high quality rubber, usually EPDM, with many excellent features including resistance to high temperatures. The hoses are reinforced with textile braid (or cord) or steel braid depending on the working pressure.

  • Use safely

    For steam application, it is recommended to use rubber hoses with fittings assembled with safety clamps. Over time, material (rubber) exposed to steam gradually loses its natural elasticity causing leakage or even rupture of the fitting, often with catastrophic effects. Fittings attached by safety clamps can be re-tightened over the hose service life. For safety reasons, we caution against using rubber hoses with fittings permanently crimped with ferrules.

Rubber steam hoses – application examples:

Saturated steam transfer, superheated steam transfer, steam heating systems, process steam systems
Steam cleaning, hot water washing of production lines and machines in food processing

Steam has a destructive impact. Steam can cause damage to equipment, serious injuries or even death to personnel.  However, there is a way to avoid this hazard – the hose must be correctly matched with the application, all recommendations given below concerning installation, maintenance, storage, inspection must be obeyed together with H&S guidelines.

Selection of rubber hose for steam service

While selecting a hose for a steam system, first identify its operating conditions:

  • maximum working pressure of steam
  • steam temperature
  • steam type: wet saturated steam (with water particles), dry saturated steam, superheated steam
  • dependence of saturated steam temperature on pressure (overpressure – indicated by pressure gauge) is given below:
    press. [bar]12345678910111213141516171819202224
    temp. [°C]120134144152159165171175180184188192195198201204207210213215220224
  • whether the hose will be subject to sudden pressure surges
  • whether the hose will be subject to bending while working under pressure
  • will it be used constantly or occasionally
  • will it be handled manually
  • what are the external conditions at the location, where the hose will be employed, risk of mechanical damage, are there any spilled or condensing aggressive chemicals or oils present, which may cause deterioration of hose external layer

Hose installation

  • Follow general instructions for flexible hose installation given in the rubber steam hoses handling manual.
  • Always check, if the connections (hose fittings) are designed for steam.
  • Use only special fittings designed for steam service, mounted with steam safety clamps bolted together on the hose. With these clamps the connection can be re-tightened. When mounting the fittings, follow the instructions concerning selection and assembly provided by the supplier. The bolts of safety clamps must be tightened during the entire period of hose operation. Check if the bolts are tight always before the stem system is started.
  • Avoid excessive bending of the hose near the end connections.


The hose must be correctly stored when not in use. Use a rack or a pallet to minimise the risk of hose damage when in storage. Do not hang the hose on a hook, nail or any other device which may cause puncture or damage the hose.

Periodic maintenance and inspection of steam hoses

All rubber steam hoses wear out over time.  Therefore, continuous control is of primary importance. The operator must regularly check if deterioration is not so severe as to prevent further safe use.

The operator must pay special attention to:

  • rubber lumps or blisters
  • cracks that expose the braid
  • leakage of steam near the fittings or in any other spot along the hose
  • flattening or kinks that may cause hose damage
  • decrease in steam flow rates indicating swelling of internal layer

If any of the above occurs, the hose must be shut down from service immediately. This hose must be thoroughly inspected prior to further use. The hoses are usually damaged near the fitting, where they are exposed to excessive bending and deformation. If such damage occurs, cut off the hose fitting and mount it once again. The hoses continuously used at high temperature and pressure should be periodically inspected to check if the internal layer hardens. In most cases, removing the fittings to perform the inspection is necessary.

Health and safety guidelines

  • Operators must wear appropriate working clothes covering the whole body, including gloves, rubber shoes and eye protection.  Wearing working clothes protects the body from burns in case of steam or hot water burst.
  • Always check if the working area is free of hazards and tidy.
  • Check if the bolts are tight always before the steam system is started.
  • The hose must not be left under pressure when the system is shut. This shortens the service life of the steam hose.
