Core Functions and Roles

Achieves precise sealing connection between hydraulic pipelines and hydraulic components, ensuring stable and leak-free hydraulic oil transmission; effectively transmits high pressure in the hydraulic system, ensuring uninterrupted power transmission, suitable for heavy-duty high-pressure operations; standardized interface design allows for quick and convenient installation without additional equipment layout modifications; surface anti-rust and anti-corrosion treatment resists outdoor humidity, oil, and dust environments, extending service life and protecting core components of the hydraulic system.

Suitable Scenarios

Widely used in the hydraulic systems of various construction machinery such as excavators, loaders, bulldozers, and road rollers, connecting core components such as hydraulic pipelines, hydraulic pumps, cylinders, and hydraulic valves, suitable for heavy-duty high-pressure operations such as infrastructure construction, mining, earthwork engineering, and road construction.

Common Faults and Troubleshooting

When a joint leaks, check for aging seals and loose joints. Replace the seals promptly and tighten the joint according to standards. If the connection is loose, check the thread engagement and retighten. If the threads are worn, replace the joint. If there is rust or damage, check for damage to the surface protective layer. Replace with a galvanized passivated joint and ensure proper protection. If there is a mismatch, check if the joint specifications match the equipment interface and replace with the corresponding model joint.
