High-Precision Micro & Slender Diameter CNC Turning for Demanding Thermal Management
At Xierge Precision Machinery Co., Ltd., we leverage our 30+ years of manufacturing expertise to produce premium Micro & Slender Diameter CNC Turning for high-performance thermal management applications. Since our establishment in 1990, we have understood that in EV battery cooling, server data center liquid cooling, and advanced medical equipment, even the slightest fluid leakage or flow restriction is unacceptable. We specialize in manufacturing high-precision barbed fittings, quick-disconnect couplings, and manifold adapters using our Japanese imported Star CNC Swiss-type lathes and multi-axis machining centers.
These advanced machines allow us to machine complex internal threads, precise O-ring grooves, and micro-bores with extreme concentricity and tight tolerances, ensuring a perfect, leak-free seal under high pressure. To guarantee durability against corrosive coolants and extreme temperature fluctuations, we strictly adopt premium raw materials, including naval brass, 304/316 stainless steel, and high-strength aluminum alloys. Following our core principle of "Integrity Oriented, Quality Foremost," every batch of liquid cooling fittings undergoes strict quality inspection using our complete set of testing instruments imported directly from Japan and Germany. We keep innovating to maintain sound business development, and we warmly welcome domestic and overseas clients to visit our factory and explore custom OEM/ODM cooperation opportunities.

Core Advantages of Xierge Liquid Cooling Fittings
- Leak-Proof O-Ring Groove Precision: Our Star CNC Swiss-type lathes machine O-ring grooves with micro-tolerances, ensuring perfect compression and zero fluid leakage under high-pressure cooling cycles.
- High-Pressure Structural Integrity: By adopting premium forged stainless steel and high-grade brass, our fittings resist deformation and bursting in high-pressure EV and server cooling loops.
- Multi-Axis Complex Machining: Our 4-axis machining centers allow us to complete complex geometries—such as angled ports, cross-holes, and external hex profiles—in a single setup, ensuring perfect concentricity.
- Corrosion-Resistant Surface Engineering: We apply specialized treatments like hard anodizing and passivation, ensuring our fittings withstand harsh glycol mixtures and deionized water without degrading.
- Ultra-Clean Internal Passages: To prevent coolant contamination, all fittings are processed through our industrial ultrasonic cleaning machines to remove 100% of machining chips and cutting fluids.
- Imported Metrology Assurance: We utilize Japanese and German imported thread gauges, CMMs, and optical comparators to verify thread integrity and dimensional accuracy on every batch.
- 30+ Years of OEM/ODM Customization: Since 1990, we have continuously innovated, allowing us to rapidly develop custom quick-disconnect fittings and manifold blocks directly from your thermal management CAD models.
Payment Methods & Global Logistics Solutions
Secure International Payment Terms:
To facilitate seamless global trade for our B2B clients, we offer flexible and secure payment options. For mass production orders of liquid cooling fittings, we accept standard T/T (Telegraphic Transfer) with a 30% advance deposit and 70% balance before shipment. For large-scale international supply contracts, we are fully capable of processing Irrevocable Letters of Credit (L/C) at sight. For initial prototyping, sample orders, or custom tooling fees, PayPal and Western Union are also available to expedite the process.
Global Logistics & Protective Packaging:
We provide comprehensive end-to-end shipping solutions under FOB, CIF, and DAP Incoterms. For urgent prototypes or small batches, we utilize expedited international couriers such as DHL, FedEx, and UPS. For bulk mass production, we offer highly competitive sea freight (LCL/FCL) and air cargo rates through our trusted global forwarder network. Recognizing that liquid cooling fittings require pristine sealing surfaces, we utilize specialized packaging: each fitting is individually capped to protect threads and O-ring grooves, wrapped in VCI (Volatile Corrosion Inhibitor) anti-rust paper, and secured in custom EPE foam slots within sturdy export-grade cartons or wooden cases to prevent any transit damage.
FAQ
Leak prevention is critical in liquid cooling systems. We machine O-ring grooves using our Japanese Star CNC Swiss-type lathes, which offer extreme stability. We tightly control the groove width, diameter, and depth to tolerances within ±0.01mm. Furthermore, we use imported Japanese optical comparators and micrometers to inspect every groove, ensuring the optimal squeeze ratio for the O-ring is achieved.
Yes. We strictly adopt premium materials like 304/316L stainless steel and high-grade naval brass, which possess excellent tensile strength and thermal stability. We can also perform pressure decay testing on request to verify that the fittings can safely handle the dynamic pressure spikes and thermal expansion common in EV thermal management loops.
Internal debris can severely damage coolant pumps and clog micro-channels in cold plates. After machining, all fittings go through our dedicated industrial ultrasonic cleaning machines. This process, combined with high-pressure flushing, ensures that all micro-burrs and cutting fluids are completely removed from blind holes and internal threads before the parts are packaged.
Absolutely. Aluminum is highly popular for liquid cooling due to its weight and thermal conductivity. We machine the coupling blanks to precise dimensions, leaving a specific allowance for the hard anodizing layer. After the surface treatment, we use custom gauges to ensure the internal diameters and locking mechanisms still fit perfectly with mating components.
With over 30 years of expertise, we are fully equipped to machine all major international thread standards, including NPT, BSPP (G), BSPT (R), and Metric (M). We use imported Japanese and German thread gauges to perform 100% inspection on critical sealing threads to ensure zero leakage during assembly.
Yes, we operate with integrity and keep innovating. Our engineering team can review your 3D CAD models and provide DFM feedback. We help optimize wall thicknesses, tool access angles, and O-ring groove designs to reduce machining costs, improve structural integrity, and ensure smooth high-volume mass production.
