Do you guys know how the hose is manufactured?
Today I am going to show something basically important about hydraulic hose material properties.
The raw material for manufacturing a hydraulic hose can determine the quality of the hydraulic hose.
Hydraulic hoses are critical components of hydraulic systems. They transmit hydraulic fluids from one component to another, facilitating movement and power transmission. As such, it is crucial to choose the right hydraulic hose material for your application.
In this ultimate guide, well explore hydraulic hose material properties and how they affect the hoses performance.
The hydraulic hose is normally made of multiple materials, and the most common material property is rubber.
And the rubber material for making hydraulic hoses is a synthetic rubber, which is the main body to compose the hydraulic hose structure.
So lets see the hydraulic hose structure first.
hydraulic hose structureA whole hydraulic hose pipe is structured with 3 parts, inner tube, reinforcement, and outer cover.
The inner tube is made of oil-resistant synthetic rubber, the reinforcement is made of high tensile stainless steel wire, cotton thread, textile and etc, the outer cover is made of synthetic rubber too.
This is the composition of the standard hydraulic hose, and the hydraulic hose manufacturer will adjust the proportion of material properties to achieve a certain hydraulic hose performance.
For example, the experienced hydraulic hose engineer will increase the proportion of NBR (Nitrile Rubber) synthetic rubber material to make the inner tube of the hydraulic hose, to give it better oil resistance.
Here are some frequently used hydraulic hose pipe material properties.
The widely used material property is rubber material, which is used to create the inner tube and outer cover of the hydraulic hose. Here are various types of rubber material, so lets go first to introduce rubber for hydraulic hose production.
Synthetic rubber is a common hydraulic hose material. It is durable, flexible, and can withstand high pressure and temperature. It is also resistant to abrasion, ozone, and weathering. However, synthetic rubber is not suitable for use with certain fluids, such as petroleum-based oils, fuels, and solvents.
Thermoplastics, such as nylon and polyurethane, are also used in hydraulic hoses. They are lightweight, flexible, and can withstand high pressure and temperature. They are also resistant to abrasion, chemicals, and weathering. However, they are not as durable as synthetic rubber and are not suitable for use with high-temperature fluids.
Teflon, also known as PTFE, is a popular hydraulic hose material for high-temperature applications. It can withstand temperatures up to 450°F and is resistant to chemicals, including acids and bases. It is also non-conductive, making it ideal for use in electrical applications. However, Teflon is not suitable for use with petroleum-based fluids.
Stainless steel is a hydraulic hose material used for high-pressure applications. It is durable, flexible, and can withstand extreme temperatures. It is also resistant to corrosion and abrasion. Stainless steel hoses are often used in industries such as aerospace, marine, and food processing.
Hybrid hoses combine different materials to achieve specific performance characteristics. For example, a hybrid hose may have a synthetic rubber inner tube for flexibility and a stainless steel outer braid for durability. Hybrid hoses can also include multiple layers of materials, such as nylon and synthetic rubber.
Neoprene can maintain excellent flexibility within the hydraulic hose temperature range of -40°C and 100°C, and it is used to solve the hose abrasion problem at certain temperatures.
Neoprene rubber material has excellent resistance, ozone resistance, heat aging resistance, oil resistance, and solvent resistance. Good chemical resistance and excellent flame resistance.

So Neoprene rubber has a wide application, and here we usually use Neoprene to produce the hydraulic hose, of course, it can also be made for many other products, such as the outer cover of cables and wires, industrial gaskets, hoses, belts, adhesive tapes, joint sealants for construction engineering and etc.
The stainless steel is used to make a reinforced layer of the hydraulic hose, to add much more strength to the hydraulic hose body. According to the steel wire reinforcement, the hydraulic hose can be divided into two main types.
Braided hydraulic hose and spiral hydraulic hose, and you can know the difference between spiral vs braided hydraulic hose. Stainless steel wire is an important material for making the hydraulic hose reinforcement layer.
Here are hydraulic hose factory will source bulk steel wires, ensure the quality of the hydraulic hose. The braided hydraulic hose will have excellent flexibility, much stronger with more layers of steel wire reinforcement, and the spiral hydraulic hose will be designed with strength.
And the spiral hydraulic hose can add more layers of spiral steel wires, to make the 4-wire spiral hydraulic hose, and 6-wire spiral hydraulic hose.

Hydraulic hoses are critical in almost all hydraulic systems, so imagine the hassle if it suddenly breaks down. Also, the hoses flexibility allows the components of the system to be placed in the most convenient or efficient positions because it can get around corners, limited spaces, and go across any lengths.
But these days, selecting the right type of hose can be very challenging because of the vast number of choices. How can you differentiate a kind from the other? Is there a more straightforward way to choose the right type?
So, we have made a guide that contains everything that you need to know to find the right hydraulic hose for your needs. What are you waiting for? Read more to find out!
Today, hydraulic hoses are composed of three parts: an inner tube (which transports the fluid), a reinforcement layer, and a protective covering/outer layer. The inner tube is usually designed to be flexible, and it needs to be compatible with the specific type of fluid that will pass through it. This part of hydraulic hoses is usually made from synthetic rubber, PTFE (or Teflon), and thermoplastics. On the other hand, the reinforcement layer is made from single or multiple sheaths of braided wire, textile yarn or spiral-wound wire. Lastly, the protective covering is made to be resistant to oil, abrasion, and the elements. So, you will need to choose the specific type of protection that you need depending on the environment that the hose will be used.
If you want to design a hydraulic system, there are seven factors that you should consider when selecting the right hose and couplings. So, to make your life easier while determining the proper tube for a new application, remember the acronym STAMPED. It stands for Size, Temperature, Application, Materials, Pressure, Ends, and Delivery. Heres why these things are essential:
This type of hydraulic hose is lighter than most metal type counterparts, and it will make it easier to move the hydraulic system. It can also be made more durable by adding a fiberglass or steel mesh which helps minimise bending, bulging, and scratching. Also, it can withstand high temperatures, and it can also be used to link with several hose fittings.
Recommended: The FLUIDKRAFT Hydraulics HD Diehard can be used for power units or power applications like winches, windlasses, and furlers. Also, the inner tube is made of synthetic rubber that is reinforced with two braids of steel wire which makes it abrasion-resistant. The hose is also available in cadmium-plated steel, but stainless steel is available if you ask for it.
There are times that hydraulic hoses made of steel are too cumbersome to use. So, you should try a Teflon (also known as PTFE) hydraulic hose with steel reinforcement because it has all of the benefits of steel hoses. Also, this type has an even higher heat resistance than rubber. If your system involves a boiler or a blast furnace, this type is the one that you should choose. Aside from that, it is very light, which is essential if youre at the field.
Recommended: The Fluidkraft RTH1 Series Hose Lining is made from Teflon (PTFE) and is reinforced with one braid of Grade 304 stainless steel wire with high tensile strength. It is recommended for dealing with high-pressure hydraulic oil lines. Also, the hose is chemically pure, nonreactive, and has no leachable additives. Aside from that, it is also highly resistant to high temperatures and open flame because it has a high melting point, thermal damage threshold, and auto-ignition temperature. However, you should avoid using this for fluids and gases because it can generate static electricity which may hasten the hoses degradation.
Although there is no specific hose that is designed to be a return line, it is still a vital piece in a system. Return lines are responsible for bringing fluids back to the pump where the pressure decreases. So, less expensive hoses can usually get the job done. But dont be too confident! If return lines are not maintained properly, they can cause quite a hassle when they breakdown.
Recommended: The Fluidkraft SRX Extreme has a tube that is made from synthetic rubber and is oil resistant, and it is reinforced with either one fibre or spiral braid. Also, it is covered with black synthetic rubber that is oil and abrasion-resistant. Aside from that, it meets the 30RS performance requirements that are needed for both Type 1 and Type 2 for transporting fuel. It is also rated to withstand temperatures ranging from -40oC to 100oC.
If you want a hose that can be easily stored and maintained, this is the type for you. Coiled tubes are ideal for auto repair shops, welding shops, and other businesses that value space and efficiency. Aside from that, professionals like mechanics and engineers prefer this type of hose because they can be pulled, used, and snap back in place to where it was placed.
Recommended: The Fluidkraft H12D DIEHARD is made with a bonded twin-line construction and has a self-retracting coil design. The hose is made out of nylon, reinforced with 528N-Aramid fibre, and is covered in polyurethane. Besides, the hose is rated to work at temperatures ranging from -40oC to 100oC, and it has a non-perforated cover.
Corrugated hydraulic hoses function much like expansions joints, but they are meant for use in a hydraulic system. It can accommodate sudden pressure surges or expansion due to fluctuations in the external temperature. On the other hand, articulated hoses similar to corrugated type hoses but they can be maneuvered freely around corners or twist to fit around other components.
Recommended: The Fluidkraft TMH is perfect for transporting gases and fluids in wide-ranging temperatures (from -200oC to 500oC). Although it can handle extreme temperatures, the hoses capability to handle pressure reduces as it gets hotter.
