Precision-engineered hydraulic hoses and sealing components — meeting the demanding standards of Seoul's manufacturing, construction, and energy industries.
Seoul stands as one of Asia's most advanced industrial hubs — driving consistent demand for high-performance hydraulic and pneumatic solutions across multiple sectors.
With mega-projects like GTX rail expansion, smart city developments in Mapo and Gangnam, and continuous urban redevelopment, Seoul's construction sector demands robust high-pressure hydraulic hoses for excavators, cranes, and heavy machinery — creating a significant and growing market.
The Guro and Seocho industrial districts host hundreds of precision manufacturing plants. Hydraulic hose fittings are critical components in automated press lines, CNC machinery, and robotic assembly systems — where zero-leakage performance is non-negotiable.
Seoul's push toward clean energy — including wind turbine installations and district heating systems — relies heavily on high-pressure hose assemblies for hydraulic pitch control, cooling circuits, and fluid transfer in power generation equipment.
Incheon International Airport, one of the world's busiest, requires certified hydraulic components for ground support equipment, aircraft maintenance, and fuel handling — where SAE-certified hoses and precision seals are mandatory for safety compliance.
Seoul Metro and KTX high-speed rail systems depend on hydraulic hose assemblies for braking systems, door mechanisms, and maintenance equipment. High-pressure fittings must meet strict vibration and temperature cycling requirements in these applications.
South Korean conglomerates export heavy equipment globally. Seoul-based engineering firms sourcing high-pressure hydraulic hoses for coal mining chock haulers, metal mining machinery, and offshore platforms require ISO-certified, high-cycle-life products.
The hydraulic hose and fittings market in Seoul is evolving rapidly, shaped by technology advancement, regulatory change, and shifting industrial priorities.

Shaanxi Kelong New Material Technology Co., Ltd. — established 1996 — is a leading high-tech enterprise integrating R&D, production, and sales of hydraulic hoses, combined sealing products, and longwall chock haulers.
Shaanxi Kelong New Material Technology Co., Ltd. was established in 1996. It is a high-tech enterprise, integrating R&D, production and sales. The main products are combined sealing products, High Pressure Hydraulic Hose and Longwall Chock Haulers. The products are mainly applied for coal mining, metal mining, and also widely used in civil aviation, high-speed railway, wind power and other fields. The sealing products adopt the equipment and production technology of DMH Company in Austria. The hydraulic hose production base adopts a complete set of equipment imported from Italy, with an annual output of more than 15 million meters of various hydraulic hoses. Our total annual output value is more than 58 million dollars. There are more than 500 employees. The company has an independent R&D center to support OEM and ODM projects. The annual R&D investment accounts for more than 5.6% of total revenue. The main sales markets are Asia, Oceania, East Europe and other regions, with ISO system and IRIS certificates.
Our production capabilities are built on internationally sourced technology — delivering consistent quality for Seoul's most demanding industrial applications.

The sealing products adopt the equipment and production technology of DMH Company in Austria — ensuring European-standard precision, material quality, and dimensional accuracy for high-pressure sealing applications in Seoul's industrial, railway, and energy sectors.

The hydraulic hose production base adopts a complete set of equipment imported from Italy — the global benchmark for rubber hose manufacturing precision. This enables consistent wall thickness, reinforcement integrity, and pressure rating compliance across every meter produced.
