Engineered for Korea's demanding industrial environments — from Seoul's semiconductor fabs to heavy construction sites on the Han River corridor.
Seoul is one of Asia's most dynamic industrial hubs. Its manufacturing ecosystem — spanning semiconductors, shipbuilding, construction, and smart infrastructure — generates massive, ongoing demand for precision hydraulic sealing solutions.
Seoul's relentless urban development — from GTX high-speed rail tunnels to Han River waterfront redevelopment — deploys thousands of hydraulic excavators, cranes, and TBMs, all requiring reliable cylinder seals to maintain uptime and safety.
Guro and Incheon industrial districts host major automotive, steel, and electronics manufacturing plants. CNC presses, robotic welding arms, and automated assembly lines all rely on high-performance hydraulic seals to minimize leakage and downtime.
South Korea's aggressive push toward offshore wind farms and smart grid infrastructure along the Yellow Sea coast has expanded demand for hydraulic seals rated for extreme marine and weather conditions — a segment where Kelong excels.
Seoul Metro operates one of the world's busiest subway networks. Hydraulic systems in rail maintenance vehicles, platform screen doors, and tunnel boring equipment depend on precision seals for safe, uninterrupted operation.
Incheon Port — Seoul's maritime gateway — operates massive container cranes and ship-to-shore handling equipment. High-pressure hydraulic hoses and cylinder seals are mission-critical components in this environment.
Seoul's smart factory initiative promotes energy-efficient hydraulic systems using biodegradable oils. Our DIN EN853 hoses and PU/PTFE seals are fully compatible with eco-hydraulic fluids, meeting Korea's green manufacturing standards.
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, concentrating on hydraulic seal sets, high-pressure hoses, coal mine auxiliary transportation equipment, technological services, and more. Products have been widely applied to coal mining, civil aviation, high-speed railway, engineering machinery, wind power, and other industries. High-quality products and services are trusted by customers all over the world — including major industrial buyers in Seoul and across South Korea.
The company is the top three in the domestic coal machine sealing industry. High-pressure rubber hoses and frame-type handling vehicles are expected to enter the top three within two years. The main products hold an 8% share in the domestic market.
The hydraulic sealing sector in Seoul is undergoing rapid transformation driven by digitalization, sustainability mandates, and advanced manufacturing demands.
Seoul's factories are rapidly adopting IoT-enabled hydraulic systems with real-time seal condition monitoring. Demand for high-precision, long-life seals compatible with predictive maintenance platforms is surging across Korea's smart factory ecosystem.
South Korea's environmental regulations are pushing manufacturers toward biodegradable hydraulic fluids. Our PU, PTFE, and FKM seals are specifically engineered to maintain performance with eco-friendly oils — a critical requirement for Seoul's green factories.
Next-generation seal materials — including PTFE composites, polyurethane blends, and POM engineering polymers — are replacing traditional NBR in high-temperature, high-pressure applications common in Seoul's semiconductor and steel industries.
Post-pandemic supply chain disruptions have accelerated Seoul's industrial buyers' shift toward reliable, certified overseas manufacturers with fast delivery capabilities. Kelong's direct-export model offers competitive pricing with guaranteed lead times to Korean ports.
Seoul's machinery OEMs increasingly demand custom-engineered seals for proprietary cylinder designs. Kelong's in-house R&D center and CNC turning capabilities support full OEM customization in NBR, PTFE, FKM, PU, POM, and PA materials.
Korean industrial procurement standards demand ISO, IRIS, and KS-certified components. Kelong holds multiple international certifications, enabling direct qualification as an approved supplier for Seoul's Tier-1 manufacturers and government infrastructure projects.
From the Han River to Incheon Airport, Kelong hydraulic seals and hoses are engineered to meet the specific demands of Seoul's diverse industrial landscape.
TBM hydraulic cylinders for Seoul's GTX underground rapid transit expansion require seals with extreme durability under continuous high-pressure cycles.
Excavators, pile drivers, and hydraulic cranes deployed along Seoul's Han River corridor depend on reliable rod and piston seals for all-weather performance.
Yellow Sea offshore wind turbine pitch control and hydraulic brake systems require marine-grade seals resistant to saltwater, UV, and temperature extremes.
Hyundai and Kia production lines in the Seoul metro area use hydraulic press and welding robot cylinders — our OEM seals ensure zero-leakage precision assembly.
Cleanroom hydraulic actuators in chip fabrication facilities demand ultra-low contamination seals — our PTFE and FKM solutions meet the strictest purity standards.
Aircraft ground support equipment — including hydraulic lifts, pushback tugs, and cargo loaders — requires seals certified for aviation-grade hydraulic fluids.
Ship-to-shore cranes and container handling equipment at Incheon Port operate under extreme load cycles — our spiral-wound hoses and dual-acting seals are built for this.
Seoul's water purification and sewage treatment plants use hydraulic gate actuators where corrosion-resistant seals and biodegradable-fluid-compatible hoses are essential.
Ultra-tough, high-pressure hydraulic hose for rock-solid machinery performance in Korean mining and quarrying operations.
