Large Bore Metal Hose for Data Center Cooling
Corrugated and braided stainless steel hose assemblies, 1" to 8", built to spec by ASME-qualified welders. We fabricate 6" and 8" large-bore assemblies on a short lead. Tell us what you need.
McGill is both your sourcing partner and your fabricator for data center cooling. We pair leading hose and fitting brands with in-house assembly, testing, and certification to deliver complete, custom solutions across every hose type your cooling loops demand.
Where this Hose Runs Your Facility
Data center cooling infrastructure depends on flexible connections that can absorb movement, isolate vibration, and hold up to constant thermal cycling. McGill's large-bore metal hose assemblies are built for exactly those points in the system:
- Chilled water / glycol supply and return mains
- Chiller-to-CDU flex connectors
- Pump vibration eliminators
- Cooling tower connections
- CDU facility inlet/outlet jumpers
These are the connections that keep the facility water loop running: the joints between rigid pipe runs and the equipment that moves, vibrates, or shifts under thermal load.
Built for What Facility Water Loops Actually Do
- Absorbs thermal expansion in large-bore runs, preventing stress on flanges and fittings
- Isolates pump and chiller vibration from the piping system
- Handles glycol and water chemistry without degradation, rated for PG25 and other coolants
- Non-combustible, meeting data center fire safety requirements
- Welded ends for zero leak paths at fittings
If you're specifying or sourcing metal hose, you already know why it belongs here.
What you need to know is that McGill can build and deliver yours fast.
