Hydraulic Hose Guide – Create Sturdy Hydraulic Applications

Hydraulic hoses are taking a more and more important role in mobile vehicles and fixed production lines, and mechanical power transfer fields these years, hydraulic hose guide is necessary due to the improvement of automation control level and efficiency of modern equipment.

In simple terms, a hydraulic system uses liquid fluid – hydraulic fluids — to generate work. A lift, for example, can carry heavy loads from one point to another periodically under the power of the pressurized hydraulic fluids.

Hydraulic hoses accommodate hydraulic fluids and sustain the pressure and transfer the periodical pressure to the motion of the actuators. they can find their application in construction, agriculture, mining machine, etc.

In this article, as a professional hydraulic hose manufacturer, I will walk through all the hydraulic hoses we supply into some categories and help you figure out the popular hydraulic hoses used in the current market.

What are Hydraulic Hoses?

Hydraulic hoses are made from some polymer such as synthetic rubber, thermoplastic, or PTFE, to accommodate hydraulic fluids and transfer the power from the power creator (pump) to actuators. Hydraulic systems are vital units for some mechanical equipment.

Hydraulic hoses can sustain certain pressure lies in they have a reinforcement layer in the middle, the reinforced pattern includes fiber braided, steel wire braided and steel wire spiral wound. Different reinforced patterns result in different pressure ratings of hydraulic hose.

The hydraulic hose structure statement can guide you on how to choose the right hydraulic hose.

General hydraulic hoses consist of three fundamental layers from the inner to the outside on the analysis of the cross-section of the hose. Each of these layers plays an important role in ensuring the hose works optimally:

  • The inner or core layer ensures the hose is chemically compatible with the hose. It is the only layer that has direct contact with the hydraulic fluid, and if not chemically compatible, it could easily damage.
  • The reinforcement layer acts as a support to the inner layer. The inner layer may be chemically compatible with the fluid but not strong enough to withstand its pressure. Thus, the reinforcement layer is what helps the hose withstand pressure.
  • The outer layer is the external part of the hose – the part you see and touch. It ensures the hose doesn’t get damaged – punctured or melted by heat, for example – from the outside. So, it has to be compatible with the working environment.

Types of Hydraulic Hoses

Hydraulic Hose Guide

Hydraulic hoses have different types of classifications. The three most common classification types, however, are material, standards, and reinforcement.

  • Types of Hydraulic Hoses By Material

Hydraulic hoses typically come in rubber, thermoplastic, or Teflon material. The most common is rubber, which is popular due to its high compatibility with many hydraulic fluids. Rubber’s flexibility is also an advantage.

A rubber hydraulic hose comes with a rubber inner layer and outer layer. But the reinforcement layer is typically made with wire steel braids. The number of braid layers determines how much pressure the rubber hose will handle.

Thermoplastic hydraulic hoses are lightweight, flexible, clean, and non-conductive. They come with a nylon inner layer, a synthetic fiber reinforcement layer, and a polyurethane outer layer.

The third material, Teflon, makes a hydraulic hose that will not corrode. At least, not under normal circumstances. They come with stainless steel braid reinforcement later, and most come without an outer layer.

Teflon hydraulic hoses are popular for high-temperature applications. They also have good chemical compatibility, like rubber.

  • Types of Hydraulic Hoses By Standards

General hydraulic hose standards fall into two series: SAE J517 and DIN EN standards.

SAE is the abbreviation of the Society of Automotive Engineers, hydraulic hoses that comply with SAE standards are popular in North America. the common types are listed in the table below.

DIN EN is the abbreviation of Deutsche Industrial Norme and European Norm, this standard originated in Germany and was adopted by European Norm. The hydraulic hoses which adhere to EN have similar requirements to that in the SAE, so some hoses can meet the two standards at the same time.

  • Types of Hydraulic Hoses By reinforcement

If you are aware of the hydraulic hose structure, you will know the importance of the reinforcement, in hydraulic hoses, the reinforcement layer is the source of the working pressure rating, the reinforcement layer comes in textile(fiber) braided, steel wire-braided and spiral wound steel wire from low-pressure to high-pressure resistance for a hydraulic hose.

How To Choose the Right Hydraulic Hose

The right hydraulic hose will depend on your hydraulic system. And when weighing your options, here are five tips to follow:

  1. Ensure the hydraulic hose material is chemically compatible with the fluid you want to convey. If you are conveying hydraulic oils, for example, synthetic rubber hoses would do justice. 
  2. Ensure the working pressure of the hydraulic hose is above the actual pressure, even temporary pressure spike must be below that. Working pressure refers to the amount of pressure the hose can handle without any problems.
  3. Consider the dimensions of your hydraulic system. In particular, consider the required length, inner and outer diameter, and bending radius. These will determine the right hydraulic hose size to use. And it is the most important because a wrongly sized hose will serve no purpose.
  4. Examine the hose’s end connection. Some hoses come with pre-made fittings, while others are universal. Hoses with pre-made fittings are usually more advantageous. But if you opt for them, you must ensure the fittings are compatible with your hydraulic system.
  5. Choose a hydraulic hose that supports the accessories you will need. Most hydraulic systems need select accessories to connect the hose to other parts. Hose clamps, crimpers, and, of course, fittings are some examples.


Many people find it difficult to choose the right hydraulic hose. It is not surprising, considering all the technicalities involved in making the choice. Thankfully, the above hydraulic hose guide will make the task easier for you.

When you decide on the right hose type and size, you must purchase from a trusted hydraulic hose manufacturer. Your hydraulic hose may be the perfect size and still underperform because it is low quality.
