Product Introduction
Liquid Cooling Fittings
China Super Tech liquid cooling fittings are precision stainless steel tube and fitting assemblies for AI data center cooling, CDU systems, energy storage thermal management and other demanding coolant circuits. Available in 304 and 316L, with controlled internal surface finish, customized geometry and pre-shipment leak inspection.
Where Liquid Cooling Fittings Usually Fail
The original product content identifies three recurring procurement and installation problems: batch inconsistency, slow supplier response, and uncertain lead times for custom bends or manifolds. The practical issue is whether the delivered part continues to fit the system after the first sample.
Dimensional drift can stop assembly
Outer diameter, wall thickness or port position can shift between batches. When interfaces no longer match the approved sample, technicians may need on-site rework.
Slow answers can delay the cooling loop
Feasibility questions, drawing confirmation and lead-time checks need a defined engineering response so the connection work does not become a project bottleneck.
Special bends need controlled delivery
Custom bends, non-standard ports and manifolds require drawing review, prototype validation and a confirmed production cycle rather than an open-ended lead time.
Fitting Design for Real Cooling-System Interfaces
Liquid cooling fittings are used where straight tubing alone is not enough: tight rack layouts, CDU connections, manifold branches, custom interfaces and pre-assembled cooling loops.
For larger coolant-distribution layouts, see the Data Center Liquid Cooling Manifold Pipe and Server Liquid Cooling Manifold pages.
Technical Specifications
| Category | Parameter | Specification |
|---|---|---|
| Material | Grade | 304 / 316L stainless steel |
| Dimensional | Square tube size | 10×10 mm to 80×80 mm |
| Dimensional | Wall thickness | 0.5–3.0 mm |
| Dimensional | Length | Up to 6000 mm |
| Surface | Internal roughness | Ra ≤0.4 μm |
| Leak testing | Helium leak rate | ≤1×10⁻⁹ Pa·m³/s |
| Standards | Tube standard | ASTM A312 / JIS G3459 |
| Welding | Process control | ISO 3834 management with orbital welding |
Material grade should be selected according to coolant chemistry, dimensions and operating environment. The source content identifies 316L for glycol-based or chloride-exposed loops and 304 for pure-water or DI-water loops.
Three Controls That Affect Connector Consistency
Each 304/316L batch is checked for chemical composition against the specified stainless-steel grade.
Weld parameters are controlled under ISO 3834 quality management to improve penetration and repeatability.
Polishing, pickling and passivation are used to reach the specified internal roughness of Ra ≤0.4 μm.
Tube dimensions, wall thickness and interfaces are checked against the approved drawing.
Each connector undergoes pre-shipment leak inspection before release.
Inspection and shipment records support batch-to-batch control and project follow-up.
Customization Options
| Custom Item | Options | Verification |
|---|---|---|
| Tube geometry | Square 10×10 to 80×80 mm; round or custom | Dimensional inspection to drawing |
| Bending | Custom bend angles and radii | Bend-template / fit check |
| Connections | Custom ports, interfaces and assemblies | Interface check |
| Manifolds | Custom port count and layout | Inspection and leak test |
| Surface finish | Polishing, pickling, passivation; specified roughness | Roughness measurement |
| Length | Cut-to-length up to 6000 mm | Measurement against drawing |
Customization follows: Requirement confirmation → Solution design and drawing review → Prototype → Mass production → QC → Delivery. For projects that need integrated coolant distribution, you can also review the 316 Liquid Cooling Manifolds.
Application Fit
If the project needs the complete pipe rather than only fittings, see the 316 Liquid Cooling Pipe product page.
Procurement FAQ
1.What are liquid cooling fittings used for?They are stainless steel tube and fitting assemblies that carry coolant between servers, CDUs, manifolds and other components in liquid cooling systems. The source content covers AI data centers, CDU systems, energy storage thermal management and immersion cooling.
Yes. Customization can cover geometry, dimensions, bend angles and radii, connection interfaces, manifolds, assemblies, surface finish and cut-to-length requirements. Drawing review is part of the customization process.
The supplied specifications describe material verification, dimensional checks, controlled welding, surface-roughness verification, 100% pre-shipment leak inspection and batch traceability. These controls are intended to keep later deliveries aligned with the approved specification.
Lead time depends on the geometry, quantity and welding complexity. The source content states that standard products can ship in about 10–15 days, prototype custom connectors can be produced in about 7 days, and customized mass production commonly runs 20–30 days. Confirm the actual schedule against the drawing before ordering.
Send the required material grade, dimensions, wall thickness, connection type, bend or port geometry, quantity and application. A CAD drawing or technical drawing is recommended when the fitting is customized.
