Shaanxi Kelong New Material Technology Co., Ltd. was established in 1996 as a high-tech enterprise integrating research and development, production, and sales. Our core products include combined sealing products, high pressure hydraulic hoses used for hydraulic cylinder sealing, and long wall chock haulers. Applications extend beyond coal and metal mining industries to civil aviation, high-speed railways, wind power, and more.
We utilize advanced equipment and production technologies from DMH Company in Austria for sealing products and a complete set of Italian-imported machinery for hydraulic hose manufacturing, ensuring top-tier quality. Our annual output exceeds 15 million meters of hydraulic hoses, contributing to a total revenue over 58 million USD with a global workforce exceeding 500 employees. Our dedicated R&D center accounts for over 5.6% of annual revenue investment, enabling OEM and ODM custom solutions. Key sales markets include Asia, Oceania, and Eastern Europe with both ISO and IRIS certifications. We actively seek collaborations in coal-mining enterprises in Indonesia and globally.
As of now, Kelong New Materials boasts total assets of 600 million RMB with an annual output value reaching 300 million RMB. The workforce exceeds 400 employees, including approximately 180 skilled engineers and technicians. Notably, over 40% of employees hold college degrees, and R&D personnel account for 17.5% of the team. Over the past three years, research and development investment surpassed 7% of annual revenue.
Our company ranks among the top three in the domestic coal machinery sealing industry. The high-pressure rubber hose and frame-type handling vehicles segments aim for top three within two years. Currently, our products hold an 8% share of the domestic market. We prioritize continuous technological innovation to consistently enhance the scientific content of our products, securing an industry-leading position for technology and quality.
We warmly welcome visits and partnerships to jointly shape a brilliant, technology-driven future.

The application of high pressure hydraulic hoses for hydraulic cylinder sealing in construction machinery plays a critical role in ensuring the durability, efficiency, and safety of heavy equipment. With construction machinery becoming increasingly sophisticated—ranging from excavators, cranes, loaders to bulldozers—the demand for reliable hydraulic seal solutions capable of withstanding high pressures, wear, and harsh environments has never been higher.
High pressure hydraulic hoses serve as the lifeline of hydraulic systems in construction machines. These hoses must maintain perfect sealing between hydraulic cylinders and fluid, resisting oil leaks, abrasion, and pressure bursts. In construction scenarios, equipment often operates in extreme weather, dust, and vibration conditions, which require hoses with advanced sealing materials and reinforcement layers.
Industrial Status:
The global hydraulic hose market has witnessed steady growth supported by expanding infrastructure projects, urbanization, and mechanization in emerging economies. Particularly, Chinese manufacturers like Kelong New Materials have gained traction by combining advanced European sealing technologies with Italian precision machinery to deliver hoses that meet international standards such as SAE 100 R9.
The shift toward more environmentally-friendly hydraulic fluids and emissions regulations is driving innovation in hose materials. For example, fluoropolymer inner linings such as PTFE and specially compounded rubber blends improve chemical resistance and reduce friction, extending lifespan and lowering maintenance costs.
Development Trends:
Applications Deep Dive:
Beyond general hydraulic cylinder sealing in construction machinery, high-pressure hydraulic hoses are also vital in:
As construction machinery becomes more digital and connected, the demand for integrated sealing systems supporting smart monitoring grows. Kelong New Materials has invested over 7% of annual revenue into R&D to develop next-generation sealing products incorporating AI-driven quality control and custom application engineering services.
The transition to electric-powered construction equipment will also influence hydraulic system design, pushing manufacturers to balance hydraulic efficiency with electrification trends. High-pressure hydraulic hoses continue to be indispensable components performing critical sealing and fluid transmission roles in this evolving landscape.
Investing in high-performance hydraulic hoses today ensures lower downtime, longer machine life, reduced maintenance expenses, and safer operation for the construction machinery sector’s fast-paced and demanding environments.
