Kingdaflex is a professional manufacturer of hydraulic hose end fittings, offering crimp-on fittings, flange fittings, threaded fittings, and custom-engineered solutions for high-pressure hydraulic systems. We support OEM & bulk orders with stable quality and global standards.
Crimp-on hydraulic hose fittings are one of the most widely used hose end fittings in high-pressure hydraulic systems. Designed to be permanently attached using professional crimping equipment, these fittings provide a secure, leak-free connection between the hose and the system component.
Kingdaflex manufactures crimp-on fittings in various sizes, materials, and pressure ratings, ensuring compatibility with different hydraulic hoses and stable performance in demanding industrial, mobile, and heavy-duty applications.
Hydraulic flange fittings are designed for high-pressure applications where secure and stable connections are critical. Kingdaflex produces SAE flange fittings compliant with SAE J518 standards, including 3000 PSI and 6000 PSI pressure ratings.
These fittings use a flat-face flange design with O-ring sealing, making them ideal for large-diameter hydraulic hoses and systems subject to vibration or pressure fluctuations, such as construction machinery, mining equipment, and industrial hydraulic systems.
Threaded hose end fittings are commonly used in hydraulic systems that require flexible installation and easy maintenance. Kingdaflex manufactures threaded hydraulic hose end fittings with NPT, BSP, and JIC thread standards to meet different regional and application requirements.
These fittings are engineered for precise thread tolerances and reliable sealing performance, ensuring compatibility with valves, pumps, cylinders, and other hydraulic components across a wide range of industrial and mobile hydraulic applications.
Quick-disconnect hydraulic couplings allow fast and convenient connection or disconnection of hydraulic hoses without tools. They are especially suitable for applications that require frequent hose changes, system maintenance, or equipment mobility.
Kingdaflex supplies quick-disconnect couplings in multiple configurations and pressure ratings, designed to minimize fluid leakage and maintain system efficiency while improving operational safety and productivity.
Hydraulic hose end fittings are widely used in construction machinery such as excavators, loaders, and cranes. They ensure secure, high-pressure connections for hydraulic cylinders, pumps, and control systems operating under heavy loads and constant vibration.
We offer multiple material options for hydraulic hose end fittings to match different working conditions and performance demands. Common materials include carbon steel for general high-pressure applications, stainless steel for corrosion-resistant environments, and brass for lower-pressure systems. Material selection can be customized based on fluid type, operating temperature, and environmental exposure.
Kingdaflex manufactures hydraulic hose end fittings in a wide range of international thread and connection standards. Available options include SAE, BSP, NPT, JIC, and ISO specifications. All threads are precisely machined to ensure accurate fitment, easy installation, and reliable sealing when connected to hoses, valves, pumps, and other hydraulic components.
Different hydraulic systems require different sealing solutions to maintain safe and leak-free operation. We provide hose end fittings designed for O-ring sealing, flat-face sealing, and cone sealing structures. Each fitting is engineered according to pressure ratings and application demands, ensuring stable sealing performance under high pressure, vibration, and dynamic operating conditions.
Surface treatment options are available to enhance corrosion resistance and extend the service life of hydraulic hose end fittings. Common finishes include zinc plating, nickel plating, and passivation. These treatments help protect fittings against moisture, chemicals, and harsh working environments, while also improving appearance and consistency for export and OEM supply.
