Hydraulic hoses are one type of pipeline used for transporting liquid media, consisting of an inner rubber layer, a reinforcement layer, and an outer rubber layer. The inner rubber layer is usually made of synthetic rubber, the outer rubber layer is made of wear-resistant, weather aging resistant synthetic rubber or other materials, and the reinforcement layer is woven from reinforced fabric or steel wire.
Hydraulic hoses applications
What is the purpose of a hydraulic hose?
A hydraulic hose is a flexible connecting element in a hydraulic system, used to connect components such as pumps, valves, and actuators. Its core function is to transport hydraulic oil or other media, transferring energy from the power source to the actuator through the flow of incompressible fluid to drive mechanical actions. In addition, rubber-made hydraulic hoses possess unique flexibility, which can buffer the impact of pump pulsations and mechanical movements, protecting the pipeline and reducing noise.
Hydraulic Hoses for Construction Equipment
Hydraulic hoses are widely used in various construction machinery, such as excavators, loaders, bulldozers, etc. A large number of hydraulic hoses are required in the hydraulic system of construction machinery to achieve hydraulic transmission and control.
Hydraulic hoses are commonly used in boom and stick cylinders, vibration control, slewing systems, travel motors, steering systems, and hydraulic breakers.
These machines typically face continuous vibration, severe impacts, and exposure to large amounts of dust and mud, as well as frequent movement. Most operate outdoors, therefore, hydraulic hoses must be able to withstand high pressure, high pulses, abrasion resistance, and aging resistance.
Recommended hydraulic hose models are:
· SAE 100R2AT
· SAE 100R12
· SAE 100R13
· SAE 100R15
· EN856 4SP
· EN856 4SH
These steel wire reinforced hoses provide excellent pressure resistance and long service life under severe construction conditions.
Hydraulic Hoses for Agricultural Machinery
Hydraulic drive systems are widely used in agricultural machinery, and hydraulic hoses are also widely used as pipelines for conveying liquid media. Modern agricultural equipment utilizes hydraulic hoses, including tractors, harvesters, seeders, sprayers, plows, etc., primarily for hydraulic lifting, steering, PTO attachments, loading arms, and hydraulic brakes.
Agricultural equipment often operates in environments exposed to dust, mud, rain, UV radiation, and seasonal temperature changes. Therefore, hoses must remain flexible while resisting aging and UV radiation, being abrasion-resistant, and supple.
Hydraulic Hoses in Agricultural Equipment
Recommended hydraulic hose models:
· SAE 100R1AT
· SAE 100R2AT
· Textile braided hose for return lines
· EN857 1SC/2SC compact hydraulic hose, suitable for installation in confined spaces.
The Mining and Metallurgical Industry
The mining and metallurgical industry requires specialized hydraulic hoses and supporting accessories with high performance indicators to ensure the stable operation and safety reliability of the entire system, as well as drilling equipment and large cranes in the petroleum exploration and development field.
Hydraulic hoses used in mining equipment can transmit power, such as mining excavators, drilling rigs, underground loaders, dump trucks, and crushers. Mining is one of the most demanding environments for hydraulic hoses applications, facing ultra-high pressure, severe abrasion, continuous vibration, intense mechanical impact, and contact with corrosive dust or rocks. Hydraulic hoses need to be extremely wear-resistant, high-pressure resistant, and withstand high pulses.

Recommended Hoses:
· SAE 100R13
· SAE 100R15
· EN856 4SP
· EN856 4SH
These four-layer steel wire reinforced spiral hoses offer excellent high-pressure and impact resistance, while the wear-resistant outer layer provides a longer service life and enhanced safety.
Hose for Oil and Gas Industry
Hydraulic hoses used in the oil and gas industry serve as critical flexible components for high-pressure power transmission and the transport of hazardous media; they are specifically designed to ensure reliable connections amidst equipment relative motion, vibration, and extreme conditions—such as high pressure, high temperature, corrosion, and deep-sea external pressure—encountered during drilling, oil extraction, and subsea operations.
Hydraulic hoses in this sector frequently operate in high-pressure, high-temperature, and corrosive environments, necessitating resistance to fire, heat, and oil.
Recommended hose types include standard SAE hydraulic series (e.g., R1, R2, 4SP, 4SH) and specialized API well-control series (e.g., API 16D, 7K, 17K).
Marine Hydraulic Hoses Applications
Many mechanical equipment in marine ships uses hydraulic drive, such as cranes, drainage pumps, boiler controls, etc. This equipment requires stable, effective, and durable hydraulic hoses.
These hydraulic hoses are commonly used in ship steering systems, deck lifting systems, and hydraulic lifts, and are exposed to working environments involving seawater immersion and corrosion, high humidity, and continuous vibration. Corrosion-resistant hydraulic hoses and stainless steel fittings are recommended.
Automotive Industry
In the automotive industry, hydraulic hoses are used to transmit hydraulic power for functions such as steering, pressurization, and braking; they are commonly utilized in vehicle manufacturing, modification, and repair.
Hoses for this sector must withstand continuous, repetitive movement and high-pressure environments, requiring them to be lightweight, flexible, and high-pressure resistant.
Recommended hose types include:
SAE 100R1AT/SAE 100R2AT, offering excellent high-pressure resistance
Compact hydraulic hoses, designed for easy installation in the confined spaces of a vehicle
Thermoplastic hydraulic hoses, which are lightweight and flexible, helping to reduce vehicle weight.
Other industries
Aerospace: The extension and retraction systems of aircraft flaps, landing gear, and other parts are controlled by hydraulic systems, which require the use of high-quality hydraulic hoses to transport liquid media. Material handling equipment relies on hydraulic hoses to safely lift, transport, and position heavy loads.
Chemical industry: Hydraulic systems used in chemical production, such as hydraulic pumps and reactor stirring devices, deliver hydraulic oil to drive mechanical movements. In petroleum refining and other scenarios, they may also be used to transport corrosive fluids, requiring hoses to be corrosion-resistant and chemical-resistant.
Summary
Hydraulic hose is a very important pipeline widely used in various industrial fields. It has the characteristics of high pressure resistance and wear resistance, and has a wide range of applications in hydraulic machinery, agricultural machinery, ships, airplanes, automobiles and other fields. There is a huge demand for high-quality, efficient, safe and reliable hydraulic systems and related components in any industry or field, which has led more and more professional manufacturers to focus on developing and manufacturing more advanced products to meet market demand. We believe that in the future, more new materials and technologies will be applied to this field to further promote the development process of the industry. This industry will also develop faster and better.
