We offer a vast selection of crimped and reusable fittings, including but not limited to JIC, BSP, NPT, ORFS, and metric types. The material and design of these fittings are customized to ensure a perfect, leak-proof connection to your equipment, preventing costly downtime and maintenance.
We provide a comprehensive private labeling service, allowing your brand name, logo, part number, and technical specifications to be permanently printed on the hose layline. This simplifies inventory management, ensures product traceability, and reinforces your brand identity in the market.
For assemblies with angled fittings, we can ensure the precise orientation of the fittings to one another. This is crucial for proper installation and prevents the hose from kinking or twisting, which can lead to premature failure and reduce the efficiency of the hydraulic system.
To enhance durability in harsh environments, we can add a protective sleeve or guard. Options include spring guards, nylon fabric sleeves, or polyurethane wraps. This customization protects the hose from external abrasion, impacts, and heat, significantly extending its service life.
Reinforcement layers are the backbone of a hydraulic hose, and the type of reinforcement used directly impacts its cost. A cheaper hydraulic hose often uses a single or double layer of braided synthetic fiber, which is suitable for low-to-medium pressure applications. In contrast, higher-pressure hoses, which are more expensive, require multiple layers of spiral or braided high-tensile steel wire for increased durability and pressure resistance.

The hydraulic hose manufacturing process involves a series of precise steps to create a durable, multi-layered product. It starts with forming the inner tube, followed by the careful application of reinforcement layers and the protective outer cover. Each stage is critical to ensuring the hose can withstand high pressure and harsh environmental conditions.
Inner Tube Extrusion: A specialized extruder forms the seamless, flexible inner tube from synthetic rubber or thermoplastic. This layer is crucial as it contains the fluid and must be compatible with its chemical properties and operating temperatures.
Reinforcement Application: Braided or spiraled layers of steel wire or textile yarn are applied over the inner tube. This step provides the hose’s essential strength, allowing it to withstand extreme hydraulic pressures and impulse cycles without bursting.
Cover Extrusion: A final layer of synthetic rubber or a thermoplastic compound is extruded over the reinforced core. The outer cover protects the hose from external damage, including abrasion, ozone, UV rays, and oil, ensuring a long service life.
Vulcanization (Curing): The entire hose is placed in a vulcanization chamber where it undergoes a curing process under heat and pressure. This step permanently bonds the different layers, significantly improving the hose’s physical properties, elasticity, and overall durability.
Finishing and Inspection: After vulcanization, the hose is cut to specified lengths, and end fittings are attached to create complete assemblies. Each finished hose then undergoes rigorous testing—including pressure and impulse tests—to ensure it meets or exceeds all performance and safety standards before being shipped.
Custom hydraulic hoses are essential across a wide range of industries where fluid power is critical. Tailored to specific pressure, temperature, and material needs, they ensure optimal performance and safety for heavy machinery, transportation, and industrial systems. Their versatility makes them indispensable for both standard and specialized equipment.
Construction Machinery: Used in excavators, bulldozers, and cranes, custom hoses handle the high-pressure demands of hydraulic cylinders, booms, and attachments. Their robust construction is designed to withstand the harsh, abrasive environments of construction sites.
Agriculture and Farming Equipment: Tractors, harvesters, and irrigation systems rely on custom hoses for steering, braking, and implement control. Hoses are often tailored to resist UV radiation and agricultural chemicals, ensuring long-term reliability in the field.
Mining and Quarrying: In these extreme environments, custom spiral-wound hoses are crucial for heavy-duty drilling rigs, haul trucks, and crushers. They are engineered to endure high-pressure surges and constant abrasion from rock and debris.
Oil and Gas Industry: Hoses are used in drilling rigs, offshore platforms, and refinery equipment. They are customized for extreme temperatures and to safely transport flammable fluids, with specialized covers to resist fire and chemical corrosion.
Transportation and Automotive: In heavy trucks, buses, and commercial vehicles, custom hoses are used in power steering, braking systems, and suspension. They are designed to withstand vibration and temperature fluctuations, ensuring consistent and safe operation on the road.
A custom hydraulic hose is an assembly specifically manufactured to meet the unique requirements of an application, including precise length, diameter, pressure rating, and fluid compatibility. Unlike standard off-the-shelf hoses, custom hoses are engineered to fit a specific piece of machinery or system, optimizing performance and safety.
Using a custom hydraulic hose ensures a perfect fit and eliminates the risks associated with using an incorrectly sized or rated hose. A properly specified hose prevents leaks, improves system efficiency, and significantly extends the life of your equipment by withstanding the exact pressure, temperature, and environmental conditions of your application.
