The global demand for high pressure hydraulic connectors is surging as heavy industries shift toward more powerful and compact machinery. From deep-sea drilling to aerospace landing gear, the reliability of hydraulic systems hinges on the integrity of their connectors and hoses.
Modern trends focus on "Smart Hydraulics"—incorporating sensors into hydraulic connectors to monitor pressure drops and leakage in real-time. Additionally, there is a massive move toward "Green Hydraulics," utilizing eco-friendly materials and seals that resist degradation from biodegradable hydraulic fluids.
Companies are no longer just looking for the "cheapest" parts; they seek a balance of cost-efficiency and uncompromising safety. A reliable high pressure hydraulic connectors exporter must provide ISO-certified products that can withstand extreme pulsations and environmental stressors.

Shaanxi Kelong New Materials Technology Co., Ltd. was founded in 1996, which grew from Xianyang Kelong Rubber Products Institute. It is a technological innovation company integrating R&D, production, and sales, concentrates on hydraulic seal sets, high-pressure hoses, coal mine auxiliary transportation equipment, repairing coal mine auxiliary transportation equipment, and technological services. The products have been widely applied to Coal mining industry, Civil Aviation, High-speed railway, Engineering machinery, Wind power, and etc. The high-quality products and services are trusted by customers all over the world.
Choosing Kelong as your Cheap High Pressure Hydraulic Connectors Exporter doesn't mean sacrificing quality. It means leveraging the world's most advanced manufacturing hub with specialized European technology.
Our sealing products adopt the equipment and production technology of DMH Company in Austria. Our hydraulic hose production base adopts a complete set of equipment imported from Italy, ensuring precision that matches global tier-1 standards.
In the past three years, R&D investment accounted for more than 7% of our total income. With enterprise R&D personnel accounting for 17.5% of our workforce, we are at the forefront of material science for high-pressure applications.
With ISO and IRIS certifications, our professional team conducts strict checks throughout the production process, guaranteeing top-notch product quality for mining, aviation, and railway sectors.
In deep underground mines, hydraulic systems operate in high-dust, high-humidity environments. Our SAE 100 R12 and R13 hoses are designed to resist abrasion and withstand explosive pressures.
Saltwater corrosion is the enemy of hydraulic connectors. Our ultra-high pressure wire spiral hoses are treated for corrosion resistance, perfect for offshore oil rigs and wind turbines.
Tunnel Boring Machines (TBM) require massive hydraulic force to move rock. Our KDAS and PSZ sealing kits ensure no pressure is lost during critical drilling operations.
The landscape of hydraulic engineering is evolving at a rapid pace. As an experienced High Pressure Hydraulic Connectors Exporter, Shaanxi Kelong has witnessed the shift from simple rubber connectors to complex, multi-layered spiral wire reinforced systems. In the current industrial era, the focus is on "Power Density"—the ability to transmit more power through smaller, more flexible conduits.
Today's High Pressure Hydraulic Connectors Companies are investing heavily in material science. The use of advanced polymers like PU (Polyurethane) in KDAS combination seals and oil-resistant NBR (Nitrile Butadiene Rubber) in hoses like the SAE 100 R6 and R12 ensures that systems can operate for thousands of hours without maintenance. Furthermore, the integration of Italian-imported manufacturing lines allows for tighter tolerances, reducing the risk of "catastrophic failure" in high-pressure environments common in civil aviation and high-speed railways.
International buyers from Europe, North America, and Southeast Asia are increasingly looking toward China for their procurement needs. The reason is simple: Scale and Specialization. A company like Kelong, which holds a significant share in the domestic coal machine sealing industry, can offer competitive pricing due to massive production scales while maintaining Austrian-level quality standards. When searching for a "Cheap" exporter, smart procurement officers look for "Total Cost of Ownership" (TCO)—a connector that is affordably priced but lasts longer is infinitely cheaper than a low-quality part that causes a system shutdown.
As one of the top three companies in the domestic coal machine sealing industry, Shaanxi Kelong is your trusted partner for high-pressure solutions. We combine over 25 years of research with global manufacturing excellence.
