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.

Hydraulic hose is everywhere, and now we are going to know something important basically about the types of hydraulic hose.

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.

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.

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, here 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.

Layers of reinforcement:

The reinforcement of the hydraulic hose can be designed with different layers, and you can see some from the hydraulic hose reinforcement above.

One layer of reinforcement:  SAE 100R1AT / DIN EN857 1SC, DIN EN853 1SN, SAE 100R5, SAE 100R6

Two layers of reinforcement: DIN EN853 2SN, DIN EN857 2SC, SAE 100R3SAE 100R16

Four layers of reinforcement: EN853 4SH, EN853 4SP, SAE 100R9, SAE 100R12

Six layers of reinforcement: SAE 100R13, SAE 100R15

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, 4-layer steel wire hydraulic hose. More layers of hydraulic hose structured 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.
