Engineered to withstand extreme environments with a patented cone-seal design, ensuring 100% leak-proof operations.
Under our registered trademark IKIN, operated by TM Hydraulic, we focus on a singular mission: engineering and manufacturing the world's most reliable hydraulic test points, connectors, and micro-bore test hoses. Because we specialize exclusively in this domain, we have honed our design, engineering, and metallurgy standards to a level that broad-spectrum manufacturers simply cannot match.
Our state-of-the-art 5,000㎡ production facility is backed by rigorous ISO 9001 and SGS certifications. We are currently building new advanced smart workshops to further scale capacity. Our products feature a patented zero-leakage, cone-seal design, supported by a 100% inspection protocol and a comprehensive 3-year warranty.
Every hydraulic coupling we fabricate undergoes multi-stage inspections, including material composition analysis, thread profiling, and extreme pressure leakage testing.
Analyzing the evolution of hydraulic connectivity in high-precision, heavy-duty industrial systems.
Modern hydraulic systems in wind turbines, aerospace, and deep-sea exploration operate at increasingly high working pressures, often exceeding 630 bar. This requires diagnostic points and connectors to possess a minimum 4:1 safety factor. Connectors must withstand rapid pressure spikes (hydraulic shock) without seal failure.
Environmental policies globally (such as EU REACH and EPA guidelines) penalize fluid leaks heavily. The industry is moving away from traditional metal-to-metal joints toward elastomer-sealed interfaces (like Viton/FKM DKO and ORFS). These advanced seals adapt to thermal expansion and vibration-induced clearances.
Industry 4.0 dictates continuous system diagnostics. Pressure test points act as the primary interface for digital sensors and transducers. Modern hydraulic architectures embed high-pressure diagnostic ports at critical loops to facilitate real-time monitoring and fluid sampling without dismantling connections.
Global procurement managers are consolidating suppliers to counter logistical volatility. The shift towards "One-Stop Industrial Fluid Sourcing" places premium demands on Chinese manufacturers who can provide not only standard DIN/ISO components but also customized configurations, short lead times, and reliable technical documentation (material mill test certificates, RoHS conformity, and salt spray test records).
Leveraging advanced multi-axis CNC Swiss machining, automated visual detection systems, and automated warehouse management to deliver consistent tolerances within ±0.01mm.
TM Hydraulic integrates digital planning with optimized raw material purchasing. Located in Changzhou City, Jiangsu Province, our factory sits in the heart of China’s advanced manufacturing belt. This proximity provides us with direct, reliable access to premium steel mills, high-grade heat treatment facilities, and advanced surface plating plants.
Our automated setup ensures we can scale production rapidly to fulfill large OEM orders while maintaining the flexibility to manufacture custom, low-volume components without high tooling costs.
From importing European engineering standards to running a world-class manufacturing hub, here is our journey of continuous growth.
Our initial years as the exclusive distributor of Germany's Beta brand in China established a deep understanding of European standards. When we transitioned to manufacturing our own test fittings in 2014, we targeted wind power—a demanding application requiring exceptional vibration resistance and temperature tolerance.
Founded as the exclusive distributor of Germany’s Beta brand in China, managing market promotion and engineering services nationwide.
Terminated partnership with the German brand to focus on designing and manufacturing our own proprietary testing fittings.
Began R&D on proprietary hydraulic test fittings, targeting wind power applications to run field testing in demanding environments.
Established our manufacturing facility in Changzhou, Jiangsu Province. Assembled an engineering team to start mass production.
Recognized as a “High-Tech Enterprise of Jiangsu Province” twice, validating our manufacturing processes and design patents.
Certified as a Municipal Engineering Technology Research Center and a "Gazelle Enterprise of Jiangsu Province". Now supplying major brands globally.
Providing high-precision hydraulic diagnostics to leading industrial hubs across the globe.
TM Hydraulic supplies hydraulic test points and micro-bore hoses to Europe, North America, Southeast Asia, Latin America, Australia, and Africa.
We customize threads and configurations to fit different regional standards. This includes NPT and UNF for North American construction equipment, BSPP for European machinery, and Metric threads for Asian heavy industrial applications.
Our commitment to quality, engineering expertise, and zero-defect goals make us a trusted supplier to major brands.
Our production operations are ISO certified, ensuring consistent, batch-to-batch quality control for every connector we manufacture.
Our patented cone-seal design prevents leaks, protecting hydraulic systems from pressure drops and fluid contamination.
We test every diagnostic coupling at full proof pressure before packaging, preventing out-of-box defects.
With over 10 years of focus, we specialize exclusively in test points, hoses, and gauge connections.
We are a verified supplier to major industry brands such as SANY Crane, XCMG, Parker, Hawe, and Caterpillar.
We provide OEM laser logo marking and custom packaging solutions, helping you build brand value with your customers.
Expert answers to common engineering and procurement questions regarding hydraulic test points, standards, and material options.
Our test points and diagnostic couplings are engineered to comply with ISO 15171-2 standards. This ensures interchangeability with standard test points globally, allowing you to connect ISO-compliant diagnostic equipment, sensors, and micro-bore test hoses.
Traditional metal-to-metal seals can develop micro-leakages under heavy vibration. Our patented cone-seal design features a dynamic elastomer interface. When tightened, the soft-seal element conforms to the mating seat, creating a reliable seal even under pressure spikes and vibration.
We offer our standard test points in high-tensile carbon steel protected by eco-friendly Zinc-Nickel plating, which resists red rust for over 720 hours in salt spray testing. For offshore marine, chemical processing, or coastal wind applications, we manufacture couplings in premium Stainless Steel 316L and 304.
Standard configurations are usually kept in stock for immediate shipment. For customized configurations or OEM orders, lead times typically range from 15 to 30 days depending on component complexity and volume. We keep minimum order quantities flexible to help you qualify components and verify designs.
