As a leading 4-wire hydraulic hose manufacturer in China, we specialize in producing high-pressure hoses that meet global standards. Our advanced manufacturing processes, including precision spiral winding and vulcanization, ensure every hose delivers exceptional durability and performance. We are committed to providing reliable solutions for the most demanding hydraulic applications in various industries.
Inner Tube: This seamless, synthetic rubber tube contains the hydraulic fluid. It’s designed to resist degradation from oil, water, and other hydraulic fluids.
Four Spiral Wire Reinforcement: Four layers of high-tensile steel wire are wound in alternating spirals. This gives the hose its exceptional strength and resistance to high pressure.
Adhesion Layer: A special rubber layer between the wire and the inner tube. It prevents the layers from delaminating, ensuring the hose’s structural integrity under pressure.
Outer Cover: This tough, synthetic rubber cover protects the hose from external damage. It provides resistance against abrasion, ozone, and harsh weather conditions.
Exceptional Pressure Resistance: The four layers of high-tensile steel wire provide superior strength, enabling the hose to withstand extreme working pressures and pressure surges.
Enhanced Durability: The robust construction protects against external damage from abrasion, punctures, and harsh weather, leading to a longer service life in tough conditions.
Improved Safety: Its high-pressure rating and structural integrity significantly reduce the risk of hose failure, preventing dangerous fluid leaks and potential injuries on the job site.
Optimal Performance: The hose’s design ensures a consistent flow of hydraulic fluid, minimizing energy loss and maintaining the efficiency of hydraulic systems.
We manufacture a complete range of 4-wire hydraulic hoses for your high-pressure applications. Our hydraulic hoses are made with premium materials and advanced manufacturing processes, ensuring exceptional durability, reliability, and superior performance to meet the most demanding industrial needs.
We offer SAE 100R12 hydraulic hoses, which are designed for high-pressure applications where a tight bend radius is required. This hose features four layers of high-tensile steel wire reinforcement, providing excellent resistance to pressure and impulse cycles while maintaining good flexibility for easy routing in confined spaces.
We offer EN856 4SH hydraulic hoses, a super-high-pressure solution for the most severe applications. This hose has four layers of high-tensile spiral steel wire, making it incredibly robust and durable. It’s built to withstand constant pressure surges and high abrasion in environments like mining, construction, and large industrial machinery.
We offer EN856 4SP hydraulic hoses, which are a strong, high-pressure option for general hydraulic applications. This hose features a more flexible design with four layers of spiral-wound steel wire. It is well-suited for medium-to-high pressure lines on mobile equipment and machinery where a balance of flexibility and strength is needed.
We provide four key aspects to customize your 4-wire hydraulic hoses, ensuring they are perfectly suited for your specific high-pressure applications. Our goal is to deliver a product that not only meets but exceeds your performance expectations, offering superior durability, safety, and efficiency for your hydraulic systems.
We can customize the inner tube material to ensure compatibility with a wide range of hydraulic fluids, including petroleum-based oils, synthetic fluids, and fire-resistant emulsions. This tailored approach prevents material degradation, ensuring the hose’s longevity and preventing fluid contamination in your system.
We offer customization of the outer cover to protect the hose from environmental damage. You can choose from materials with enhanced resistance to abrasion, ozone, UV radiation, and harsh weather conditions. This specialized cover extends the hose’s lifespan, even in the most demanding operating environments.
We can manufacture hoses to your specific diameter and length requirements. Whether you need a small-diameter hose for a compact machine or a long hose for a large-scale industrial application, we can provide a solution that minimizes waste and ensures a perfect fit for optimal performance.
We can supply hydraulic hoses with a variety of end connections to ensure perfect compatibility with your equipment. You can choose from different thread types, including NPT, BSP, and JIC. We ensure the connections are precisely crimped to prevent leaks and provide a secure, reliable seal under high pressure.
A 4-wire hydraulic hose is a type of high-pressure hose used in hydraulic systems, distinguished by its internal reinforcement structure. It is constructed with four layers of spiraled, high-tensile steel wire wound in alternating directions around an inner tube.
This design provides exceptional strength, making it ideal for applications that require a robust solution capable of withstanding extreme working pressures and pressure surges.
The primary differences between 4SH and 4SP hydraulic hoses lie in their pressure rating, flexibility, and intended applications, which are all determined by their internal reinforcement. Both types are high-pressure hoses with four layers of steel wire reinforcement, but a 4SH hose uses a heavier gauge of spiral wire, making it a “Super High” pressure hose.
This robust construction allows the 4SH hose to withstand greater pressure, but it also makes it less flexible. A 4SP hose, with its lighter-gauge spiral wire, offers a balance of high pressure resistance and greater flexibility, making it a more versatile option for general-purpose high-pressure applications.
Pressure Rating: 4SH is a super-high pressure hose, while 4SP is a high-pressure hose.
Flexibility: 4SP hoses are more flexible and have a tighter bend radius than the more rigid 4SH hoses.
Applications: 4SH is ideal for heavy-duty, demanding applications like mining and large construction equipment. 4SP is suited for general high-pressure hydraulic lines on various mobile machinery.
Weight: The heavier wire in 4SH makes it noticeably heavier than a comparable 4SP hose.
