Hose fitting & couplings PDF CATALOGUES

At Qingdao VIH Hose Co., Ltd., we understand that reliable hydraulic systems depend on more than just high-quality hoses - they require hydraulic fittings and couplings that ensure leak-free connections, durability, and seamless performance. As a leading manufacturer of hydraulic solutions in China, our hydraulic fittings are engineered to meet global standards, supporting industries from construction and mining to agriculture and manufacturing.

Comprehensive Range of Hydraulic Fittings & Couplings

Our extensive product line covers a full spectrum of hydraulic fittings and couplings, designed to adapt to diverse hose types, pressure requirements, and connection standards. Key offerings include:
1. Transition Joints
Bridging different thread types (metric, American, British, Japanese), our transition joints ensure compatibility between components in complex hydraulic systems. Ideal for connecting pumps, valves, and cylinders with varying port specifications.
2. Hose Joints & Sleeves
Precision-machined hose joints and sleeves for secure attachment to hydraulic hoses (3/16 inch to 4 inch). Available in steel wire braid/spiral hose compatible designs, with options for crimped or reusable connections.
3. Mining-Specific Fittings
Heavy-duty mining hydraulic couplings built to withstand abrasive environments and high pressure. Features include anti-corrosion coatings and reinforced structures, meeting the rigorous demands of mining machinery.
4. Quick-Disconnect Couplings
High-flow quick release hydraulic couplings for rapid, tool-free connection/disconnection. Perfect for applications requiring frequent hose changes, such as agricultural equipment and mobile machinery.
5. Pressure Measuring Joints
Engineered for accurate pressure monitoring, these fittings integrate seamlessly with gauges and sensors, ensuring real-time system performance tracking.
6. Non-Standard Custom Fittings
We specialize in custom hydraulic fittings tailored to unique project needs. From specialized threads to custom materials (stainless steel, brass, carbon steel), our R&D team collaborates with clients to deliver precision solutions.

Hydraulic Fittings Quality & Materials: Built to Last

At VIH, quality is embedded in every fitting:
- Premium Materials: selected high-grade carbon steel, stainless steel (304/316), and brass to resist corrosion, wear, and extreme temperatures.
- Advanced Manufacturing: 80+ CNC lathes and forging equipment ensure dimensional accuracy and consistent performance. Our forged hydraulic couplings feature superior strength compared to cast alternatives.
- Rigorous Testing: All fittings undergo pressure testing, tensile strength analysis, and leak detection in our in-house lab, alongside raw material inspections (ozone aging, abrasion resistance) to meet SAE, DIN, and ISO standards. 

Hydraulic Fittings Applications Across Industries

Our hydraulic fittings and couplings are trusted in critical applications:
- Construction: Connecting hydraulic hoses in excavators, loaders, and concrete pumps.
- Mining: Withstanding high pressure in drilling rigs and material handlers.
- Agriculture: Ensuring reliable performance in tractors, harvesters, and irrigation systems.
- Industrial Manufacturing: Supporting hydraulic presses, injection molding machines, and automated production lines.
