Company History
A history of evolution from standard distribution to high-tech, specialized manufacturing excellence.
2009.7
The company was founded as the exclusive distributor of Germany's Beta brand in China, responsible for its market promotion and after-sales service across China.
2013.9
Partnership with German Beta was terminated due to differences in business philosophy, paving the way for our independent manufacturing pivot.
2014.1
We began developing our own hydraulic test fittings, starting with industries with the highest quality demands—wind power, to carry out rigorous reliability testing.
2017.4
After completing the product reliability verification phase, we established our manufacturing facility and built a professional team in Changzhou City, Jiangsu Province. Mass production and market promotion officially began.
End of 2019
Recognized as a “High-Tech Enterprise of Jiangsu Province,” confirming our technological independence and patent stability.
2022
Once again awarded the “High-Tech Enterprise of Jiangsu Province” title, reflecting continuous quality and manufacturing methodology upgrades.
2023
Certified as a “Municipal Engineering Technology Research Center,” driving new sealing and alloy compound breakthroughs.
2024
Honored as “Gazelle Enterprise of Jiangsu Province” and recognized with “Municipal Specialized, Refined, Special Enterprises Certification.” Established partnerships with leading companies such as SANY, XCMG, Hengli, CRRC, Bucher, Argo-Hytos, Caterpillar, Parker, Hawe, Zoomlion and so on.
Technical Roadmap & Future Outlook of Fluid Diagnostics
Pioneering the next era of intelligent pressure checking systems and highly resistant alloy coatings.
In modern industrial hydraulic systems, the pressure profile of operations has risen, requiring diagnostic test fittings to function reliably beyond 630 Bar (9,000 PSI). TM Hydraulic’s R&D roadmap is focused on three technology directions:
1. IoT Smart Diagnostic Nodes
Integrating micro-pressure transducers directly inside our standard M16x2 couplings. This allows field technicians to capture digital pressure wave data wirelessly, eliminating analog line lag and improving safety.
2. Advanced Eco-Plating
Moving beyond Hexavalent Chromium (CrVI) coatings. Our current Zinc-Nickel (Zn-Ni) formulation provides over 720 hours of salt spray protection before red rust, meeting standard offshore marine regulations.
3. Hydrogen-Ready Sealing
With clean energy machinery on the rise, we are testing modified fluoroelastomers (FKM) and specialized steel alloys to prevent hydrogen embrittlement and dynamic micro-leaking under cryogenic testing profiles.
Our engineering laboratory regularly conducts destructive hydrostatic testing up to 2,000 Bar and pressure fatigue cycles reaching 2 million strokes. By pushing materials to failure in controlled conditions, our design team ensures a safety factor of 4:1 across all products.

China Factory 4.0: Supply Chain Resilience & Efficiency
Based in the manufacturing hub of Changzhou City, Jiangsu Province, our 5,000㎡ production facility is built on lean manufacturing principles. Through modern vertical integration, we control the entire lifecycle of our pressure testing instruments from raw steel billet to packaged product.
Our machining floor features Swiss-type CNC lathes capable of holding tolerances within ±0.01mm. This precision prevents leaks at the threaded interface. Because we specialize exclusively in test couplings and hoses, we source raw materials in high volumes, shielding our partners from global supply chain cost swings.
We maintain an automated raw material and finished inventory system. This allows us to keep standard fittings in stock for next-day dispatch, shortening lead times for global OEMs who need to manage their inventory levels carefully.
Local Support & Global Compliance Framework
Ensuring cross-border interoperability and conformity to international hydraulic standards.
For international buyers, product standardization is essential. Our design team ensures every product we manufacture complies with international thread profiles and testing parameters:
Thread Compatibility
We machine threads to ISO 228-1, ANSI/ASME B1.20.1, and SAE J514 standards, including Metric, G (BSPP), NPT, JIC, and ORFS fittings.
Material Certification
Every shipment comes with EN 10204 3.1 material certificates. This traceablity ensures the mechanical properties of our steel match your safety requirements.
SGS & ISO Quality
Our quality management system is audited annually by ISO and SGS, confirming our testing and production methods remain consistent.
Additionally, we provide localization support for European and North American OEMs. We offer custom product markings, unified packaging styles, and tailored engineering support, allowing our components to integrate smoothly into your supply chain.
