Zhengna Technology manufactures custom liquid cooling server connectors with Swiss-type CNC machining, controlled sealing features, threaded connections, bore inspection, and drawing-based customization for AI server and data center cooling hardware.
Short answer: Zhengna Technology manufactures custom liquid cooling server connectors and precision fittings by Swiss-type CNC machining. The parts can be made to buyer drawings for threaded ends, sealing grooves, internal bores, wrench flats, barb features, and manifold connection geometry.
Liquid-cooled servers, AI accelerators, cold plates, CDU manifolds, and rack-level cooling assemblies often need small metal connectors with reliable sealing surfaces and consistent internal flow paths. These parts are not standard catalog hardware for every project. Many buyers need drawing-based customization for space, thread, O-ring, material, and assembly requirements.
| Design area | Common customization choices | Why it matters |
|---|---|---|
| Material | Stainless steel, brass, aluminum, copper alloy, or drawing-specified material | Corrosion resistance, thermal behavior, strength, and cost |
| Connection features | External/internal threads, barbs, grooves, flats, step bores, cross holes | Fit with cold plates, manifolds, hoses, and quick-connect assemblies |
| Sealing geometry | O-ring grooves, chamfers, sealing faces, controlled surface finish | Leak prevention and repeatable assembly |
| Process route | Swiss-type turning, live-tool milling, drilling, tapping, deburring, cleaning | Stable production for small precision connector geometry |
| Inspection | Thread gauges, bore checks, groove dimensions, appearance and burr control | Reduces assembly risk before shipment |
For long, small-diameter, or feature-dense connectors, Swiss-type CNC machining helps keep concentricity and feature repeatability stable in production. Zhengna Technology can combine turning, drilling, tapping, grooving, and milling in one process route, then add secondary operations such as deburring, surface treatment, ultrasonic cleaning, or assembly support when required by the project.
We do not recommend choosing a connector only by outside diameter. For liquid cooling applications, the drawing should define the sealing method, thread standard, internal bore, edge break, allowable burr condition, material grade, surface finish requirement, and inspection points.
To quote accurately, please send a 2D drawing or 3D file, material requirement, annual volume, target application, critical dimensions, surface finish or plating requirement, and any leak-test or cleanliness requirements. If the design is still early, Zhengna Technology can review the manufacturability risks and suggest questions to confirm before sampling.
Yes. This product page is for custom liquid cooling server connectors, not fixed-size catalog fittings. We quote and manufacture according to customer drawings and specifications.
Yes. O-ring grooves, step bores, chamfers, threads, and sealing faces are typical precision features for Swiss-type CNC connector parts. Final dimensions should follow your drawing and inspection standard.
Typical applications include AI servers, data center liquid cooling, cold plates, manifolds, electronics cooling, thermal management systems, and compact fluid connection assemblies.
Yes. Zhengna Technology can support sample development and repeat production after the drawing, inspection points, and material requirements are confirmed.

Short answer: If you are comparing custom UQD liquid cooling connector suppliers, review both the commercial product page and the technical audit resources before sending an RFQ. The most important risks are sealing geometry, O-ring groove control, bore and thread quality, burr prevention, cleanliness, and prototype-to-production repeatability.
Short answer: UQD-style connector parts should be reviewed together with the broader AI liquid-cooling hardware scope and the supplier-audit checklist, not as isolated machined fittings.
