Engineered to withstand extreme pressures and mechanical stress, compliant with international standards including SAE and DIN EN.
Monterrey, Nuevo León, is currently experiencing a historic industrial transformation. As the premium hub for North American nearshoring, the metropolitan area hosts over 30% of Mexico's manufacturing output. Sectors such as automotive assembly, aerospace components, heavy metallurgy, and agricultural machinery require absolute reliability in fluid power transmission.
In Monterrey's highly demanding factory environments, downtime translates directly to financial loss. Hydraulic systems powering structural presses, robotic machinery, and logistics material handlers require heavy-duty high-pressure hoses and precise sealing elements. Extremes in summer temperatures require hydraulic hoses constructed from specialized compounds that resist cracking, thermal aging, and high-frequency vibrations.
Kelong New Materials provides a secure supply chain for Mexican tier-one manufacturers, offering European-quality components at highly competitive global rates to support Monterrey's next-generation smart factories.

A technological innovation leader integrating R&D, production, and sales of state-of-the-art hydraulic seal sets and high-pressure hoses.
Shaanxi Kelong New Materials Technology Co., Ltd. was founded in 1996, which grew from Xianyang Kelong Rubber Products Institute. We specialize in hydraulic seal sets, high-pressure hoses, coal mine auxiliary transportation equipment, technological services, and engineering diagnostics. Our solutions are deployed worldwide in demanding sectors like civil aviation, high-speed rail, offshore drilling, wind turbines, and large-scale mining operations.
Combining high-precision European equipment with efficient manufacturing infrastructure to deliver robust mechanical components.
Our premium sealing products utilize CNC machining equipment and manufacturing technology from DMH Company in Austria. This system allows us to manufacture custom seals up to 3000mm in diameter with micron-level tolerances, using specialized PU, NBR, FKM, and PTFE compounds.
Our high-pressure hydraulic hose production base uses automated braiding and spiraling equipment imported from Italy. These systems guarantee consistent wire tension during manufacturing, preventing inner tube deformations and ensuring high burst pressure safety margins.
From deep-sea drilling to renewable energy installations, our components perform under extreme mechanical and environmental conditions.
High-pressure hydraulic hoses engineered for under-ground coal and mineral extraction machinery.
Hydraulic lines engineered for consistent pressure transmission in mobile cranes and material handlers.
Corrosion-resistant steel braided PTFE hoses designed for marine environments and offshore platforms.
Hydraulic pitch-control hoses built to withstand extreme high-altitude ozone and thermal cycling.
High-pressure cylinder sealing systems designed for rock-boring and heavy excavation machines.
State-of-the-art automation and strict quality management systems optimized to support global OEMs.
Integrating CNC milling, automatic rubber vulcanization, and real-time thickness monitoring to ensure consistent quality across large production runs.
Equipped with impulse test stands, digital ozone aging chambers, and low-temperature bending test facilities. All components undergo 100% pressure testing before shipping.
Strategically located near major shipping corridors, enabling structured transport schedules to Mexican ports (Manzanillo, Altamira) and streamlined customs integration.
Monterrey’s seasonal climate, characterized by summer heat and humidity, accelerates the chemical degradation of standard industrial rubbers. Under high-frequency cyclic loading, inferior sealing materials undergo thermal degradation and extrusion failure, resulting in system fluid loss.
Kelong utilizes specialized material compounds developed for stability under demanding operating conditions:
Comprehensive selection of wire-braid and spiral reinforced hoses, custom-engineered PTFE liners, and complete cylinder seal kits.
Providing regulatory compliance support and structured delivery options for Mexican manufacturers and North American supply chains.
For manufacturers exporting from Monterrey to the United States and Canada, compliance with USMCA Rules of Origin is critical. Kelong provides comprehensive material safety data sheets (MSDS), material composition reports, and quality certification documentation to support regional value content calculations.
Our experienced export division handles all international customs documentation, standard packaging requirements, and commercial invoicing to streamline clearing processes at ports of entry, including Altamira, Veracruz, and Laredo.
"Our logistics team partners with regional freight forwarders in Mexico to provide flexible delivery options, including Delivered Duty Paid (DDP) or Free on Board (FOB) terms."
