Hydraulic Hose
About Hydraulic Hose
A hydraulic hose is a specially engineered, flexible conduit designed to transmit fluid power within a hydraulic system. The scientific definition of a high pressure hydraulic hose centers on its ability to contain and direct pressurized liquids, enabling the transfer of energy from one point to another. Constructed from synthetic rubber hose materials, thermoplastic, or PTFE, a hydraulic hose is reinforced with one or multiple layers of high-tensile steel wire or textile fibers. Its primary purpose is to withstand extreme internal pressures while maintaining flexibility, making it indispensable for transmitting power in mobile and industrial machinery. Typical applications include construction equipment (excavators, loaders), agricultural machinery (tractors, harvesters), mining operations, and manufacturing plants. Whether you need a hydraulic hose for sale for a vehicle brake lines hydraulic hose replacement or a massive industrial hydraulic hose for a stamping press, understanding its construction is key.
At HENGHUA, we transcend the role of a mere supplier; we are a dedicated solution provider for complex fluid power challenges.

Specifications for Hydraulic Hose
HENGHUA provides a comprehensive range of hydraulic hose types, each engineered for specific pressure demands and applications. Below we detail the common specifications and construction features that define our offering.
Wire Braided Hydraulic Hose: The Workhorse of Fluid Power
Wire Braided Hose is constructed with one or two layers of high-tensile steel wire braid, offering excellent flexibility and resistance to medium-to-high pressure impulses. It is the most common type of hydraulic hose used in general industrial and mobile applications.
Size Range:Â 3/16 inch to 2 inch (5 mm to 51 mm).
Working Pressure:Â Up to 6,000 psi (415 bar), depending on size and construction.

Temperature Range: Continuous service from -40°F to +212°F (-40°C to +100°C) for standard types, with high-temperature options available.
Structure and Material:
Inner Tube:Â Oil-resistant synthetic rubber hose compound (Nitrile – NBR).
Reinforcement Layer:Â One or two layers of high-tensile steel wire braid.
Outer Cover:Â Abrasion, ozone, and weather-resistant synthetic rubber (Chloroprene – CR or synthetic blend).
Wire Spiral Hose: Engineered for Ultra-High Pressure
Wire Spiral Hose is designed for the most demanding, ultra-high pressure applications, such as those found in heavy earthmoving and mining. It features four or six layers of spiraled heavy-gauge steel wire for superior strength.
Size Range:Â 3/4 inch to 2 inch (19 mm to 51 mm) and larger.
Working Pressure:Â Up to 6,000 psi (420 bar) and beyond, with some large-bore hoses handling extreme pressures.
Standard Compliance:Â Designed to standards like SAE 100R12, SAE 100R13, SAE 100R15, and EN 856 4SP/4SH/R12/R15.
Pulse Performance:Â Engineered to endure over 500,000 or even 1,000,000 impulse cycles at elevated pressures.
Structure and Material:
Inner Tube:Â Oil-resistant NBR or special compounds for high-temperature fluids.
Reinforcement Layer:Â Four or six alternating layers of high-tensile steel wire spiral, providing maximum radial strength.
Outer Cover:Â Abrasion and cut-resistant synthetic rubber, often with a pinhole for safety to warn of hose failure.
Hydraulic Hose Fittings and Assemblies
A hose assembly is a complete unit consisting of a length of hydraulic hose with a termination attached to each end. HENGHUA provides a full range of connection options to ensure a leak-free, reliable system. We supply crimped fittings for a permanent, factory-quality bond, and reusable fittings for field repairs. Our inventory includes a vast array of hydraulic hose fittings, such as adapters, flanges, and various thread types (JIC, NPT, ORFS, BSP). To protect your investment, we also offer protective sleeves and guards to prevent abrasion and external damage. You can download our complete pdf catalog for detailed dimensions and specifications.

Selection and Usage Considerations
To maximize the life and safety of your hydraulic hose, consider these guidelines:
Selection Criteria:Â Always match the hose’s working pressure to the system’s maximum surge pressure. Ensure the inner tube material is compatible with the fluid (e.g., use FKM for high-temperature or aggressive fluids). Verify the temperature range and ensure the minimum bend radius is not less than the specification.
Installation Tips:Â Never twist the hose during installation; use a second wrench on the fittings. Allow some slack in the length to accommodate pressure-induced shortening and expansion. Ensure hose runs are not in contact with abrasive surfaces; use protective sleeves or guards where necessary.
Maintenance Practices:Â Regularly inspect hoses for signs of cover cracking, blistering, leaks, or kinking. Check that all crimped fittings and adapters are secure and free from corrosion. Replace any hose that shows signs of wear or damage immediately.
Technical Insights: Braided vs. Spiral
The choice between wire braided hose and wire spiral hose depends on pressure demands. Braided construction offers excellent flexibility for dynamic applications with moderate pressures. Spiral reinforcement, with its multiple layers of heavy wire, provides the radial strength necessary to contain extreme pressures found in heavy-duty earthmoving equipment, making it ideal for high-impulse, high-pressure circuits.
