hydraulic hoses

Hydraulic hoses are an integral part of various machines that professionals use daily. You can find hydraulic hoses in trucks, construction machines, mining machines, and factory equipment. A hydraulic hose transfers fluids, or energy in a broader sense, from one place to another. Their flexibility enables them to bend around objects while functioning properly. Designers and engineers use hydraulic hoses for various applications. Hydraulic hose manufacturers create hose reel using different materials to meet the specific needs. Are you interested to learn more about hydraulic hoses that enable various important machines to work correctly? Keep reading if you said "yes"!

What Are They Made Of?

A basic hydraulic hose consists of at least three layers, namely:

  1. The inner tube
  2. The reinforcement layer
  3. The outer layer


Inner Tube

The inner tube or layer's purpose is to transfer the fluids from one place to the other. Compatibility of the inner tube with the type of fluid it will transfer is necessary for proper functioning. An inner tube will lose its functionality in no time if it transfers an incompatible fluid. Increased flexibility is another factor that determines the life of the inner tube. Manufacturers use materials like synthetic rubber and Teflon to create the inner tube. These materials are compatible with fluids like petroleum.


Reinforcement Layer

This tube has the function to support the fragile inner tube. The reinforcement tube produces sheath protection and enables the inner tube to transfer fluids properly. These tubes usually consist of braided textile or wire. Reinforcement tubes contain either plain wire or spiral-wound wire. Tubes with textile reinforcement are preferred for tight routing in machines that have low-pressure fluid circulation. On the other hand, the braid wire tubes are better to use in high-pressure systems. Spiral tubes find their applications in systems that produce premature fatigue.


Outer Tube

The outer tube has the function to cover both the reinforcement layer and inner tube. These outer tubes come in different types to meet the specific weather needs. Outer tubes have to be hard enough to withstand abrasions. Different reacting chemicals are a common thing in many industries: the outer tubes must consist of materials that can resist the effects on the hose of these chemicals. Many hose manufacturers use synthetic rubber to create the outer tubes.

These three layers made up the hydraulic hoses that find typical applications in almost every industry. But you cannot make use of even the best-quality hydraulic hoses if you don't know how to install them properly. Picking the hydraulic hose installation in Australia service has helped many industry owners to get their machines working correctly.


Selecting the Proper Hose Type

Choosing the appropriate type of hose is an essential step for industry owners. A machine can never work correctly if it has an incompatible hose. Designers often use the term STAMPED to quickly remind what type of hose is perfect for different applications. The STAMPED acronym stands for:

  • Size
  • Temperature
  • Application
  • Materials
  • Pressure
  • Ends
  • Delivery

The given standards are explained here:


Size is the most significant factor to keep in mind while selecting the replacement hose or to install a new one. A hose of improper dimensions will never work correctly or limit the power of the system. The ability of the hose to fit on hose-support clamps or bulkheads is essential as well. Designers and engineers remember this while choosing the hose. They use a caliper with great precision to measure the length and inner diameter of the hose. Both long and short hoses that are not compatible with the size required in the machine are going to render your machine useless in no time. That's why hose installers and repairers need to correctly measure the hose and install it fittingly.



Hoses are divided into different categories based on the range of temperature they can endure. A machine that transfers high-temperature fluids requires hoses that withstand high temperatures. Installing a low-temperature hose in such a machine can lead to severe problems. This is why hose installation providers are cautious about the temperature range of the hose they are installing in a machine. Temperature sleeves come in handy to save the hose's outer layer from abrasion in places where fluid temperature but the surroundings are super-hot. 



It is a fact that all hydraulic hoses are not created equal. Hose installers have to choose the right type of hose for the proper functioning of the machines. The factors like the bending ability of a hose, its temperature resistance, and other factors influence the type of hose used.



Materials present in the inner tube are not the same for all types of fluids. One has to ensure that the hose they are installing is compatible with the fluid it will carry. Using a hose that reacts to the fluids leads to the hose's short life and may cause leakage. The hydraulic hoses are famous for taking petroleum-based fluids with no problems.


Ability to endure the pressure

The pressure of the fluids is a deciding factor to employ the right type of hydraulic hose. Inserting an incapable hose in the machines that move the fluids with high or low pressure can lead to several problems. Designers have to keep the pressure in mind as the pressure of the fluid running inside the hose has direct results on the machine's performance.


Hose ends

Connecting the hose to the machine demands special attention. The mechanical interface that connects the hose with the machine has to provide leakage-free fluid circulation. Two common types of hose ends are permanently-attached couplings and field-attachable couplings. Several threads and thread diameter decide what kind of hose end will be used.



An ideal hose repair service provider keeps the availability of hydraulic hoses in mind while installing or repairing hoses. Factors like price, availability, and flexibility to use influence choosing a specific hydraulic hose.



Hydraulic hoses are excellent as they enable virtual machines to run correctly. Remember to choose a hose repairing service that knows the details mentioned above and knows well about hose repairing.
