# AI Server Liquid-Cooling Manifolds

> AI liquid-cooling manifolds are quote-ready when the circuit, port standards, internal intersections, seal geometry, coolant compatibility, cleanliness and leak-test method are explicit. Cross-drilled passages without a deburring and plugging plan create avoidable contamination and reliability risk.

## Components and applications

- Rack distribution manifolds
- Server and tray manifolds
- Cold-plate distribution blocks
- CDU interface hardware

## Recommended manufacturing route

1. Review the flow circuit and port schedule.
2. Machine external datums and intersecting passages.
3. Deburr, plug and clean through a defined route.
4. Inspect ports and execute the specified leak test.

## Drawing and RFQ controls

| Control | Guidance |
|---|---|
| Port standard | Call out thread, sealing method, depth and gauge requirement. |
| Internal intersections | Provide deburring access and identify zero-loose-chip zones. |
| Test boundary | Define installed plugs, fittings and assembly state during test. |

## Inspection to define before production

- CMM report for ports, mounting and seal locations
- Documented internal cleaning and visual scope
- Pressure-decay or helium test to the RFQ boundary

## Standards and documentation scope

- **Customer coolant specification**: Material, finish and residue compatibility must be supplied.
- **Customer leak-test procedure**: No generic pressure claim replaces the actual test boundary.

## Buyer questions, answered

### Can blind manifold intersections be fully deburred?

Only when the geometry and method allow verification. Otherwise the circuit may need access plugs, a changed intersection or a validated special process.

### What should a manifold leak-test specification include?

State medium, pressure, temperature, dwell time, installed plugs or fittings, allowable loss and whether the acceptance applies before or after finish.
