View DetailsDeep-Dive: High-Pressure Hose Diagnostic Solutions
Modern high-pressure hydraulic systems operate under relentless cycles of dynamic load and severe pressure spikes. Whether integrated within massive earth-moving machinery, complex wind turbines, offshore drilling stations, or automated industrial factories, maintaining optimal hydraulic pressure without oil leaks is critical. TM Hydraulic provides premium, leak-free test couplings and high-performance micro-bore test hoses designed to facilitate safe, immediate fluid analysis under full system pressure (up to 630 Bar).
By specializing exclusively in the production of hydraulic test points, coupling interfaces, and dedicated test hose fittings, we ensure our tooling designs meet the highest engineering tolerances. Every component undergoes severe verification testing, ensuring total system reliability and compliance with international standards.
"Precision diagnosis is the foundation of mechanical durability. A single leak-point in a high-pressure line can trigger system-wide pressure drops and costly operational downtime."
Our Quality Matrix
With an ISO-certified 5,000㎡ manufacturing hub, TM Hydraulic utilizes advanced manufacturing technologies to guarantee 100% leak-proof seals on every batch of production.
- Cone-Seal Design: Features a double-contact seal surface to eliminate leakage under intense vibrational feedback.
- 100% Quality Testing: Every single coupling is pressure tested in-house before shipping to ensure zero defects.
- Long-Term Warranty: Standard 3-year structural warranty on all steel and stainless steel models.
- Material Diversity: Carbon steel with eco-friendly trivalent zinc-nickel plating, plus premium Grade 304 and 316L Stainless Steel options.

About TM Hydraulic & IKIN
IKIN is our registered trademark, and TM Hydraulic is our dedicated operating company. We focus exclusively on engineering, manufacturing, and supplying hydraulic test points, high-pressure diagnostic hoses, and specialty gauge fittings.
By centering all research, development, and machinery investment on this specific niche, we have attained a high degree of technical mastery. Our cone-seal designs deliver absolute zero-leakage performance under high system vibrations and extreme temperature variations. We proudly offer a 3-year warranty and are a trusted supplier to major global brands, including SANY, XCMG, Parker, Hawe, GE, Rexroth, and Caterpillar.
Why Focus Matters
"Many suppliers treat test points as a side product alongside general hydraulic fittings. By focusing 100% of our capacity on test points and diagnostic micro-bore hoses, we maintain higher quality consistency, lower leakage rates, and deeper application expertise than generic manufacturers."
Our History & Evolution
From distributing European brands to building an engineering-driven manufacturing powerhouse in Jiangsu.
Founded as the exclusive distributor of Germany's Beta brand in China, taking charge of marketing and after-sales service nationwide.
Terminated the partnership with German Beta due to divergence in core business philosophies, shifting focus toward independent development.
Began researching and developing proprietary hydraulic test fittings, targeting wind power projects with strict high-reliability standards.
Established our advanced production facility and engineering team in Changzhou City, launching mass production and global distribution.
Officially recognized as a "High-Tech Enterprise of Jiangsu Province" due to our innovations in leak-proof hydraulic diagnostic connectors.
Re-awarded the "High-Tech Enterprise of Jiangsu Province" title, demonstrating our sustained engineering excellence and manufacturing standards.
Certified as a "Municipal Engineering Technology Research Center", confirming our role as a key technical resource for industrial fluid power.
Awarded the "Gazelle Enterprise of Jiangsu Province" and the "Municipal Specialized, Refined, Special Enterprises Certification."
Maintaining trusted partnerships with leading industrial brands including SANY, XCMG, Hengli, CRRC, Bucher, Caterpillar, Parker, and Hawe.

Frequently Asked Questions
Technical insights, selection advice, and operational details from our engineering team.
❓ What is the maximum working pressure rating for your standard hydraulic test points?
Our standard carbon steel and stainless steel (316L/304) M16x2 connection test points are rated for a nominal working pressure of up to 630 Bar (approx. 9000 PSI) with a 4:1 safety factor. This ensures safe diagnostic operation even under sudden hydraulic pressure spikes.
❓ Are TM Hydraulic test points compatible with other global diagnostic brands?
Yes. All of our test points, hoses, and gauge connectors are manufactured to ISO 15171-2 standards. This ensures they are fully interchangeable with diagnostic systems from brands like Parker (EMA3 series), Minimess, Rexroth, and others.
❓ How does your cone-seal design prevent oil leaks under high system vibration?
Unlike typical flat-face metal seals, our test points feature a high-precision cone-seal paired with a secondary elastomeric O-ring (NBR or Viton/FKM). When connected under pressure, the metal-to-metal cone contact seals the main load, while the O-ring seals any microscopic paths, preventing leakage even under high dynamic vibration.
❓ Can you provide custom logos and OEM product kits?
Yes, we provide OEM customization. We offer custom laser marking on hexagonal flats, custom connection threads (NPT, BSPP, Metric), specialized test hose lengths, and ready-to-use pressure test kits with custom case inserts, all at no extra cost for qualified volumes.
❓ What surface treatment do you use to resist rust in marine or wind power installations?
For our carbon steel line, we use a specialized, eco-friendly zinc-nickel plating (free of Cr-VI). This coating provides over 720 hours of salt spray resistance (per ASTM B117 standards) before showing signs of red rust. For marine and wind power systems, we recommend our Grade 316L Stainless Steel line.
