As we all know that the hydraulic hose, and it can be used to convey Petroleum-based hydraulic fluid, gasoline, water, diesel fuels, lubricating oils, glycol, mineral oils, and more can be widely used for various applications, and they are used to convey Petroleum-based hydraulic fluid, gasoline, water, diesel fuels, lubricating oils, glycol, mineral oils, and more.
When it comes to hydraulic systems, the type of hose used is a critical factor in ensuring the safe and efficient operation of the system. With so many different types of hoses available, it can be overwhelming to determine which one is right for your specific application. In this article, we will discuss the different types of hydraulic hoses, their construction, and their applications.
Hydraulic hose is everywhere, and now we are going to know something important basically about the types of hydraulic hose.
Hydraulic hoses are an essential component of hydraulic systems. They are used to transmit fluid from one component to another and are subjected to a wide range of pressures and temperatures. Therefore, it is crucial to choose the right type of hose for your application to ensure safety and efficiency.
What Are Hydraulic Hoses?
Hydraulic hoses are flexible tubes made of synthetic rubber, thermoplastic material, or Teflon. They are used to transmit fluid from one component to another in a hydraulic system. The fluid can be oil, water, or a mixture of both. Hydraulic hoses are used in various applications, including construction, mining, agriculture, and industrial machinery.
How many layers are there in the hydraulic hose?
At first, we can see the structure of a hydraulic hose. A typical hydraulic hose can is composed of 3 layers, tube (inner tube), reinforcement (the reinforcing middle layer), cover (the protective outer layer).
Tube: The inner tube of the hydraulic hose is made of synthetic rubber, and most hydraulic hoses are made of rubber material. And the quality of the raw material – rubber can decide the quality of a hydraulic hose from the root. And the design and raw material (synthetic rubber) used for the inner tube layer must be engineered to be flexible, and strong enough to convey the many types of fluids, such as water, oil, and etc.
Reinforcement: And the reinforcement of the hydraulic hose is also important, and it can be designed with different layers, and the reinforcement is made of tensile steel wire, stainless steel, and many other materials.
Cover: The cover of the hydraulic hose is protective to keep the hydraulic hose safe and wearable, and it is made of rubber material too. The cover can be designed with grooves, to add much more friction to protect the hydraulic hose away from certain harms. And the cover is also important for the performance of the hydraulic hose, to ensure the hydraulic hose pipe can be exposed to a high temperature for a much longer time.
How Many Types of Hydraulic Hoses?
Here are many different types of hydraulic hoses in the industry, you need to find the right hydraulic hose for your application. You are looking for a suitable hydraulic hose to work for the hydraulic systems.
Here are 3 types of hydraulic hose in the hydraulic hose market.
These three types of hydraulic hose are categorized by reinforcement.
- Spiral hydraulic hose: The hydraulic hose consists of spiral reinforcement to add strength to the hydraulic hose, and it can be applied for high-pressure hydraulic projects.
- Braided hydraulic hose: This type of hydraulic hose consists of braided reinforcement, which is made of stainless steel wire.
- Helical hydraulic hose: This hydraulic hose is helically coiled with the steel wire, useful to prevent collapse working under any conditions, and you can find the helical reinforcement in the suction hose.
We are the leading hydraulic hose manufacturer in China, and I will share with you guys about popular hydraulic hoses that are popular in the market.
Most hydraulic hoses are made of synthetic materials, also other materials, such as thermoplastic, and Teflon, but we can classify the hydraulic hoses into different types based on the reinforcement.
Reinforcement application: The reinforcement of the hydraulic hoses can be made of different materials, there are mainly two types:
High tensile steel wire hydraulic hose is used for high pressure, up to 7000 psi; and textile braid reinforcement hose is used for lower pressure under 1000 psi. And the wire reinforcement is ranged in layers.
Widely Used Hydraulic Hose Types in Market
There are several types of hydraulic hoses, each designed to meet specific requirements based on pressure, temperature, and fluid compatibility. Some of the most common types of hydraulic hoses include:
Rubber Hydraulic Hoses:
Rubber hydraulic hoses are the most common type of hydraulic hose. They are made of synthetic rubber, which makes them flexible and durable. They are used in low to high-pressure applications and can withstand temperatures ranging from -40°C to 100°C. Rubber hydraulic hoses are suitable for applications such as agriculture, construction, and mining.
Wire-Braid Reinforced Hoses:
These hoses are made with a wire braid reinforcement layer to provide extra strength and durability, making them ideal for high-pressure applications.
Spiral-Wire Reinforced Hoses:
These hoses are similar to wire-braid hoses but feature a spiral-wire reinforcement layer instead of a wire braid. They are also used for high-pressure applications but offer improved flexibility compared to wire-braid hoses.
Textile-Braid Reinforced Hoses:
These hoses are made with a textile braid reinforcement layer and are ideal for low to medium-pressure applications. They offer excellent flexibility and are commonly used in hydraulic systems that require tight bend radii.
The thermoplastic hydraulic hose is made with a thermoplastic inner tube and reinforcement layer, making them resistant to high temperatures and harsh environments. They are commonly used in applications where high-pressure and high-temperature resistance is required.
Thermoplastic hydraulic hoses are made of synthetic materials such as nylon, polyethylene, or PVC. They are lightweight, flexible, and resistant to abrasion and chemicals. They are suitable for high-pressure applications and can withstand temperatures ranging from -40°C to 100°C. Thermoplastic hydraulic hoses are used in applications such as lifting equipment, mobile machinery, and material handling.
These suction hose is designed to transfer fluid from one location to another and is commonly used in applications where suction is required. They are typically made with a flexible and durable material that allows for easy installation and maneuverability.
These hoses are used to return fluid to a hydraulic system’s reservoir and are commonly made with a low-pressure, high-temperature material.
Teflon hoses, also known as PTFE hoses, are made of Teflon material. They are lightweight, flexible, and resistant to chemicals, heat, and corrosion. They are suitable for high-pressure applications and can withstand temperatures ranging from -70°C to 260°C. Teflon hoses are used in applications such as chemical processing, pharmaceuticals, and food processing.
Metal hoses are made of stainless steel or other metals. They are strong, durable, and resistant to high temperatures and pressures. They are suitable for applications such as chemical processing, power generation, and aerospace. Metal hoses can withstand temperatures ranging from -200°C to 600
Layers of Hydraulic Hose Reinforcement:
The reinforcement of the hydraulic hose can be designed with different layers, and you can see some from the hydraulic hose reinforcement above.
So you can divide the hydraulic hoses into these types by the layers of reinforcement, and the hydraulic hose will be much stronger with more layers of reinforcement.
Material of reinforcement
The reinforcement of the hydraulic hose can be made with different materials, including stainless steel, steel wire, high tensile cords, and helix steel wire, cotton thread and etc, you can choose your desired type of hydraulic hose for your project.
Here I want to say that the reinforcement of the hydraulic hose is mostly made of steel wire, which can add flexibility to the hydraulic hose, making it much easier to bend, without any broken issues. And high qualified steel wire will add much more strength to the hydraulic hose, to give it longer service life.

Spiral hydraulic hose vs Braided hydraulic hose
And here are two different methods to twine the steel wire to create the reinforcement for the hydraulic hose, and you can hydraulic hose with the reinforcement made of Spiral steel wire, and also the hydraulic hose with the reinforcement made of the braided steel wire, looking like the braid.
And the hydraulic hose braiding machine can braid or spiral the steel wire layer to create the reinforcement of the hydraulic hose during the production process.
So you will see two hydraulic hose types based on the reinforcement production method, spiral hydraulic hose, and braided hydraulic hose.
About the wire braid, we have the one-layer steel wire hydraulic hose, 2-layer steel wire hydraulic hose, and 4-layer steel wire hydraulic hose. More layers of hydraulic hose structure can be used for higher pressure.
And you guys can see the difference between the spiral hydraulic hose and braided hydraulic hose, during the production process in the hydraulic hose manufacturer workshop.
And in this video, you can watch how a spiral & braided hydraulic hose is made by the hydraulic hose machine in the hydraulic hose factory.
