Hydraulic hoses explained

Hydraulic hoses graphic

You may not have heard of or know what a hydraulic hose is unless you are familiar with the hydraulic industry. However, hydraulic hoses are one of the main components that help keep our country operating. Within a hydraulic design, hoses are a vital and are what millions of people rely on in the commercial and industrial sector every day.


So, what is a hydraulic hose?

The main purpose of a hydraulic hose is to allow hydraulic fluid flow from one component to another – these components could be actuators, valves etc. Hoses are usually made up of flexible rubber or wire with multiple layers. This is because hydraulic hoses often operate under high pressure, so the added layers ensure the hose is strong and durable. This is essential because if the hydraulic hose was to fail, it would bring the whole system to a stop. They are, however, still very flexible tools enabling them to bend around other components and to reduce the noise from vibrations.

What are they different types of hydraulic hoses?

 Overall, there are two standard categories for hydraulic hoses.

SAE – The Society of Automotive Engineers

EN standard – the European standards


SAE hydraulic hoses are mostly used in the UK. Hoses must meet these requirements when being used in hydraulic systems as is it essential for human safety and efficient operation. Below are the main hose categories that fall within the SAE regulations.

Braided hose:

  • High pressure hose
  • Can either consist of one, two or three steel wires
  • Mostly used for petroleum and water-based fluids
  • Capable of operating between -40℃ and 100℃

Multi-spiral hose (high-pressure hose):

  • Very flexible
  • Mostly used for mineral and hydraulic oils and/or emulsions of water and oil
  • Great for civil engineering, construction, agricultural and oil industries

Low-pressure hose:

  • Textile braids
  • Very flexible but not good for high pressure
  • Mostly used for air, lube and anti-static delivery

Stainless steel wire-braided hose:

  • Very heavy duty
  • Can be single or double braided for more durability
  • Can cope with extreme temperatures and withstand aggressive substances
  • Suitable for different pressure conditions and is mostly used for chemical substances

Thermoplastic hydraulic hose:

  • Made of two thermoplastic material layers with the middle layer made of wire and synthetic fibres
  • Works well in low temperatures and highly resistant to abrasion
  • Great for hydraulic powered equipment

Who would need a hydraulic hose?

Hydraulic hoses are utilised in a variety of sectors. From construction to agricultural, automotive to manufacturing, aerospace to production lines and much more.


How do I know what hydraulic hose is the right hose?

There are many different aspects you need to consider when buying or replacing a hydraulic hose. These include:

  • Type of fluid/substance passing through the hose
  • The type of system the hose will be used in (end fittings and what it will be attached to)
  • Size and length of hose
  • The amount of pressure and temperature conditions

Due to there being many different variables, it is always best to consult a specialist about which hose would be best for your requirements. At our GlenFarrow Trade Counter, we can advise on and supply hydraulic hoses for multiple systems and means. To find out more call us 01775 722327 or visit us in store here.
