4 Common Types of Hydraulic Hoses

Updated: Dec 11, 2020

Hydraulic hoses can deliver hydraulic oil to hydraulic components. Hydraulic hose is usually flexible and has a multi-layer reinforced structure because it is suitable for operation under high pressure. The hydraulic hose is mainly composed of a liquid-resistant inner rubber layer, a middle rubber layer, a steel wire-wound reinforcement layer, and an outer rubber layer. The inner rubber layer has the function of making the conveying hydraulic oil bear pressure and protecting the steel wire from corrosion; the outer rubber layer is used to protect the steel wire from damage; the steel wire layer is used as a skeleton material to have a reinforcing effect.

The reinforced layer in a hydraulic hose is usually composed of some reinforced elements such as a textile braid, a steel wire braid, and a steel wire spiral. The coiled hydraulic hose is coiled with flexibility and elasticity, so it is easy to store. The corrugated hydraulic hose has corrugations and wrinkles inside. These spiral corrugations can increase the flexibility of hose compression and extension. In addition, a multi-element hydraulic hose is a hose formed by a number of flat, ribbon-shaped, or bundled elements adhered together.

Hydraulic hoses are mainly made of special synthetic rubber, and their pressure-bearing capacity is strong, they generally have good heat resistance, oil resistance, aging resistance, and bending resistance. Hydraulic hoses are mostly used in mechanized and automated hydraulic systems in engineering construction, shipbuilding, lifting and transportation, agricultural machinery, machine tools, and various industrial sectors to transport petroleum-based (such as hydraulic oil) with a certain pressure and temperature. , Mineral oil, lubricating oil, fuel oil, etc.), and water-based liquids (such as water, emulsion, etc.).

When choosing a hydraulic hose, we must consider the type of fluid being conveyed and its corrosiveness. In addition, we also need to consider whether the environment used is inferior to a place exposed to sunlight. As a result of drastic weather changes and highly corrosive polluting substances and chemical raw materials, the service life of hydraulic hoses will be shortened. The hydraulic hose can generally be divided into several types of high-pressure hose, low-pressure hose, steel wire braided hydraulic hose, and thermoplastic hydraulic hose.

Types of hydraulic hoses

1. High-Pressure Hose

The high-pressure hose is mainly divided into high-pressure steel wire braided tubing and high-pressure steel wire wound tubing. The structure of the high-pressure steel wire wound rubber hose is mainly composed of an inner rubber layer, a multi-layer steel wire braided layer, and a weather-resistant synthetic rubber outer rubber layer. The high-pressure hose is flexible, and it can be used for oilfield development and engineering construction. In addition, it can also be used to transport hydraulic oil, mineral oil, and lubricating oil. General high-pressure hoses have the highest working pressure, usually up to 70-120Mpa.

2. Low-Pressure Hose

A low-pressure hose is a low-pressure pipe braided by a single layer of textile. This type of hose can only be used in lower pressure pipelines, such as vacuum, anti-static transmission pipelines, and drain pipes. In addition, it is also suitable for use in dense pipelines. The general low-pressure hose can withstand a maximum temperature of 100°C. If the temperature of the conveying material exceeds 100°C, the hose will be quickly damaged.

3. Steel Wire-Braided Hydraulic Hose

The steel wire braided hose is very durable and suitable for transporting materials under high temperature and high pressure. Steel wire braided hoses are often used in industrial fields such as the petroleum industry and hydraulic systems for oilfield mining. This type of hose can resist fluids up to 125°C. Steel wire braided hose can be divided into a single wire braided hose and double wire braided hose.

The structure of the single-wire braided hose has only one layer of braided steel wire. The double-wire braided hose has two braided layers. Therefore, compared to the single-wire braided hose, the double-wire braided hose can withstand higher pressure and temperature.

4. Thermoplastic Hydraulic Hose

Thermoplastic hydraulic hoses usually have an inner tube, one or two reinforcement layers and a protective cover. The reinforcement layer usually has a braided structure made of polyester, polyamide, or steel wire. The reinforcement layer can provide the required strength and sufficient pressure retention. The characteristic of a thermoplastic hydraulic hose is that it can operate at a lower temperature and it is resistant to wear. Thermoplastic hoses are widely used in medium and high-pressure hydraulic applications, such as heavy construction and hydraulic lifting equipment.


In the market, there are many different types and brands of hydraulic hoses. We need to choose different hydraulic hoses according to the environment we use and the materials we transmit. To purchase a suitable hydraulic hose for your project, please contact us at +6011-7000 7687 or email us at
