What kinds of connections do AI data centers use?
Modern liquid-cooled IT environments can use cooling distribution units (CDUs), rack manifolds, cold plates, flexible hoses, tubing and specialty quick-disconnect couplings. Requirements vary by the system designer and the coolant circuit.
Coolant-compatible hose
Flexible supply and return connections, with material compatibility and bend-radius requirements defined by the project.
Quick-disconnect fittings
Low-spill or blind-mate couplings may be specified at rack or tray connections; matching standards and validation are essential.
CDU and manifold connections
Hose and tube connections between cooling distribution hardware and coolant manifolds, subject to equipment drawings.
Testing and traceability
Where required: cleanliness, leak tests, material compatibility, traceability and customer-specific documentation.
What to include in your inquiry
- Cooling-loop location: facility loop, CDU supply/return, rack manifold, or server tray.
- Coolant chemistry and concentration, operating temperature, working pressure and flow requirements.
- Inside diameter, length, routing constraints, minimum bend radius and quantity.
- End connections, quick-disconnect standard or specific manufacturer part numbers.
- Cleanliness, leak-testing, conductivity, material and traceability requirements.
- Project location, lead time, and required validation documentation.
