High-performance sealing products engineered for demanding applications across Berlin's industrial landscape.
Berlin stands as one of Germany's most dynamic industrial hubs, driving consistent demand for high-quality hydraulic sealing solutions across multiple sectors.
Berlin hosts over 5,000 industrial and manufacturing enterprises, ranging from precision engineering firms to large-scale mechanical production plants. Hydraulic seals are critical components in CNC machinery, hydraulic presses, and automated assembly lines operating across the city's industrial zones in Spandau, Reinickendorf, and Marzahn-Hellersdorf.
Berlin's ongoing urban development — including major infrastructure projects such as the BER Airport expansion, U-Bahn extensions, and large-scale residential developments — relies heavily on hydraulic-powered construction equipment. Excavators, cranes, and concrete pumps all require durable hydraulic seals to maintain operational efficiency on demanding job sites.
As Berlin accelerates its transition toward green energy, wind turbine installations and solar-tracking systems increasingly depend on precision hydraulic components. Hydraulic seals in pitch control and yaw systems must withstand extreme temperature fluctuations and continuous mechanical stress — making material quality and certification compliance essential for Berlin-based operators.
From underground rail systems to high-tech manufacturing floors, hydraulic seals play an invisible yet indispensable role in keeping Berlin moving.
Hydraulic door systems, braking mechanisms, and suspension components in Berlin's public transport network require certified, long-lasting seals.
Berlin's proximity to major German automotive clusters drives demand for hydraulic seals in test rigs, assembly robots, and production presses.
Ground support equipment and maintenance hydraulics at Berlin Brandenburg Airport demand seals with exceptional pressure ratings and chemical resistance.
Hydraulic elevator systems in Berlin's growing commercial and residential high-rise developments rely on precision rod and piston seals for safe, smooth operation.
Berlin's water infrastructure uses hydraulic actuators and control valves where seal integrity directly impacts environmental compliance and operational uptime.
Berlin's thriving medtech and research sector employs hydraulic systems in laboratory equipment, imaging devices, and precision actuators requiring ultra-clean sealing solutions.
The surrounding Brandenburg region's agricultural operations — tractors, harvesters, irrigation systems — depend on compact, high-durability hydraulic seals.
Hydraulic control systems in Berlin's power plants and district heating networks require seals that perform reliably under high temperatures and cyclic pressure loads.
The hydraulic seal market in Berlin and across Germany is evolving rapidly, driven by digitalization, sustainability mandates, and advanced material science.
Berlin's Industry 4.0 adoption is driving demand for intelligent sealing systems equipped with embedded sensors that monitor pressure, temperature, and wear in real time — enabling predictive maintenance and reducing costly downtime in automated production facilities.
German environmental regulations and Berlin's green economy agenda are accelerating the shift toward PTFE, bio-compatible polyurethane, and low-friction POM seals that reduce energy consumption and minimize hydraulic fluid contamination.
Berlin's diverse industrial base — from startups to established Mittelstand companies — increasingly requires customized seal profiles and small-batch orders with fast turnaround times, pushing suppliers to offer flexible manufacturing capabilities.
Post-pandemic supply chain disruptions have led Berlin procurement managers to diversify sourcing strategies, creating strong opportunities for certified Asian manufacturers — particularly those meeting ISO, DIN, and EU compliance standards — to establish long-term supply partnerships.
With Berlin's engineering firms pushing machinery to higher performance thresholds, demand for seals rated above 400 bar and capable of operating in temperatures from -40°C to +200°C is growing significantly across hydraulic press and mining equipment sectors.
Berlin-based maintenance engineers and procurement teams are increasingly sourcing hydraulic seals through digital platforms, requesting instant quotes and technical datasheets online — making a strong digital presence essential for international suppliers targeting the German market.
Whether you're sourcing for a single maintenance replacement or a large-scale OEM production run, Kelong New Materials delivers precision hydraulic seals with fast lead times, full technical support, and ISO-certified quality — direct to Berlin and across Germany.

With ISO and IRIS certifications, our professional team conducts strict checks throughout the production process, guaranteeing top-notch product quality that meets German and EU standards.
Quality Control
Powered by a large skilled workforce and substantial R&D investment, we manufacture a comprehensive range of hydraulic seals to meet demands across multiple industries including those prevalent in Berlin.
R&D Capability
Equipped with specialized testing laboratories and advanced equipment, every seal undergoes rigorous pressure, temperature, and fatigue testing before shipment — ensuring zero-failure performance in the field.
Our Testing
Tunnel Boring Machines (TBMs) used in Berlin's underground rail expansion projects place extraordinary demands on hydraulic sealing components. Kelong's high-pressure hoses and hydraulic seals are engineered to seal tight and last long in these high-pressure, high-vibration settings — significantly cutting maintenance costs and minimizing tunnel construction downtime.
With operating pressures exceeding 350 bar and continuous exposure to abrasive particulates, TBM hydraulic systems require seals manufactured from the highest-grade NBR, PTFE, and polyurethane compounds — exactly the materials Kelong specializes in.
