Changjia is a professional agricultural hydraulic parts manufacturer for agricultural machinery. We supply high-quality hydraulic quick couplers, sockets, breakaway couplings, and manifold components compatible with John Deere, CLAAS, and other leading tractor and combine models. Our products feature reliable performance, perfect fit, and durable construction to meet global agricultural equipment maintenance and replacement needs.

Agricultural hydraulic parts control the lifting, steering, overturning and harvesting action of tractors and harvesters, which require excellent sealing performance and pressure resistance under complex field working conditions.

Our main hydraulic agricultural spare parts cover hydraulic quick couplings, high-pressure pipe fittings, threaded adapters, valve block connectors and sealing accessories, all using high-precision machining and imported sealing rings to effectively prevent oil leakage under high hydraulic pressure. These hydraulic components are interchangeable with the original hydraulic systems of mainstream brand agricultural equipment, widely used in farm tractor lifting devices, harvester hydraulic driving units and cotton picker hydraulic picking heads. We provide different thread specifications and pressure grade options, support bulk export packaging and professional technical parameter consultation.
