Explore our precision-engineered hydraulic test points, coupling interfaces, and micro-bore test hose assemblies, standard-compliant and optimized for field diagnostics.
In modern industrial applications, fluid power is the lifeblood of infrastructure. High-pressure hydraulic circuits power everything from municipal wind turbines to mega-excavators operating in remote quarries. At working pressures frequently exceeding 400 bar, even minor dynamic leakage points can cascade into catastrophic system failure, environmental degradation, and significant financial liability.
As a global leader in high-pressure testing solutions, TM Hydraulic (under our registered trademark IKIN) has addressed these engineering challenges for over a decade. System diagnostics should not require downtime. By implementing M16x2 micro-bore diagnostic couplings and test hoses, maintenance crews can capture live system pressures, vent air pockets, and draw fluid samples for predictive chemical analysis—all under full operational workload without risk of leakage or contamination.
Our solutions conform to global standards, ensuring safety margins exceed basic operations:
IKIN is our registered trademark, and TM Hydraulic is the operating company. We specialize exclusively in manufacturing hydraulic test points & hoses — nothing else. With ISO and SGS certifications, a 5,000㎡ production facility, and new workshops under development, we ensure reliable quality and professional standards.
Our products feature cone-seal, zero-leakage designs, 100% inspection, and a 3-year quality warranty. Based in China, we offer a full range of models and have become a trusted supplier to major brands such as SANY, XCMG, Parker, Hawe, GE, Rexroth, Caterpillar and more.
From dynamic brand distributors to recognized high-tech municipal engineering research centers.
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.
Partnership with the German Beta was terminated due to differences in business philosophy, opening doors for direct R&D and production.
We began developing our own hydraulic test fittings, starting with industries with the highest quality demands—wind power, to carry out rigorous reliability testing.
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.
Recognized as a “High-Tech Enterprise of Jiangsu Province,” validating our manufacturing processes and design frameworks.
Once again awarded the “High-Tech Enterprise of Jiangsu Province” title, marking continued excellence in quality output.
Certified as a “Municipal Engineering Technology Research Center,” enhancing our material analysis and product testing labs.
Honored as “Gazelle Enterprise of Jiangsu Province.” Also recognized with the “Municipal Specialized, Refined, Special Enterprises Certification” (SRDI).
Established robust partnerships with leading enterprises worldwide, including SANY, XCMG, Hengli, CRRC, Bucher, Argo-Hytos, Caterpillar, Parker, Hawe, Zoomlion, and others.
A specialized infrastructure focusing strictly on zero-leak hydraulic diagnostics.
Our operations follow ISO 9001:2015 standards, ensuring batch-to-batch consistency and raw material traceability.
Features a metal-to-metal cone-seal design alongside secondary elastomeric seals (FKM / NBR) to guarantee fluid isolation under extreme conditions.
No sample testing shortcuts. Every single point is pressure tested in our laboratory prior to shipment to verify safety parameters.
Focus breeds mastery. For over a decade, we have developed pressure testing interfaces for high-demand diagnostic loops.
Trusted globally. We operate as a long-term supply partner for critical operations under strict quality-assurance audits.
Extend your brand presence. We offer custom laser marking for logos on body fittings and hex flats without additional manufacturing charges.
TM Hydraulic serves primary engineering distribution pipelines and OEM manufacturers in Europe, North America, Southeast Asia, Latin America, Africa, Australia, and China. We understand the specific regional standards required for global projects:
Our localized support guarantees engineering documentation (including STEP/IGS 3D CAD files, material test reports, and pressure certificates) is delivered with every batch.

Development is underway for integrated mini-transducers within standard M16x2 diagnostic ports, allowing wireless Bluetooth pressure data collection without manual tool engagement.
Refining our zinc-nickel coatings to exceed 1000 hours of salt spray testing without white or red rust, aligning with automotive and maritime regulatory trends.
Engineering multi-layer Kevlar and steel wire braided micro-bore test hoses for static and dynamic working limits of up to 1000 bar for hydro-demolition applications.
Detailed answers to common engineering queries regarding high-pressure system diagnostics.
Our standard M16x2 and DKO-style test points are rated for a nominal working pressure of up to 630 bar (9,137 PSI). They conform strictly to the international ISO 15171-2 standard, with design burst safety ratios of 1:4. Special high-pressure models are available for custom heavy-industry applications.
Our patented cone-seal interface features a metal-to-metal contact point combined with a primary elastomer O-ring (available in FKM/Viton or NBR). When the connection cap is screwed down, the metal surfaces mate under compression while the O-ring seals the clearances, preventing fluid bypass under system vibration.
Yes. The diagnostic couplings are engineered to allow safe, leak-free connection with test hoses even when the system is under pressure, up to 400 bar (5,800 PSI). The check valve within the coupling opens only after the micro-bore fitting is fully threaded onto the port, protecting technicians from high-pressure fluid release.
We manufacture a wide range of thread styles, including Metric (M8x1 to M16x2), BSP (1/8", 1/4", 3/8", 1/2"), NPT, and UNF threads. Special port configurations can be custom-machined at our Changzhou facility to meet OEM specifications.
All test points, hose lines, and adapters are packed with protective caps to prevent thread damage and internal particulate contamination. They are double-sealed in moisture-resistant plastic bags and boxed in reinforced crates, meeting shipping requirements for Europe, North America, and Australia.
