Data center liquid cooling
Liquid Cooling Hose
EPDM hose for rack and equipment cooling loops.
Share your coolant, dimensions and operating conditions to review a suitable hose specification, from bulk hose to cut lengths and assembly requirements.

Applications
Hose selection for liquid-cooled equipment
Match the hose to the coolant, connection and available space within your cooling loop.
Rack cooling circuits
Flexible hose sections for routing within rack-level cooling loops.
Server and cold-plate connections
Hose selection for compact equipment layouts, with bore, bend radius and end fittings reviewed together.
Equipment-internal loops
Coolant hose for internal equipment connections, subject to the required pressure, temperature and fluid compatibility.
Specification review
Define the hose your system needs
| Parameter | Selection basis |
|---|---|
| Hose material | EPDM options; compound and construction selected for the application. |
| Dimensions | Inner diameter, outer diameter, wall thickness and dimensional tolerances. |
| Working pressure | Specified for the selected hose and operating temperature. |
| Temperature range | Continuous operating range and any short-term temperature excursions. |
| Coolant compatibility | Review against the exact coolant, concentration and additive package. |
| Minimum bend radius | Confirmed for the selected hose size and construction. |
| Cleanliness requirements | Internal cleanliness, any extractables limits, end protection and packaging. |
| Supply format | Bulk lengths or cut sections; length tolerance and identification as agreed. |
Material grade, dimensions and operating limits are confirmed for the selected hose. Request the relevant datasheet before approving a specification.
Selection & delivery
Agree the details before sampling.
Coolant and material compatibility
Send the coolant name or datasheet, concentration and operating temperature. Material suitability is reviewed for the selected hose compound.
Routing and flow requirements
Share the available space, required bore and bend layout. Where specified, include target flow and allowable pressure drop for the hose or complete assembly.
Cleanliness and delivery
Define internal cleanliness, end-cap, packaging and traceability requirements before sampling. Any particle or extractables limits should include the test method and acceptance criteria.
Need the hose with end connections?
Add quick disconnects or other end fittings to your inquiry. Share End A / End B interfaces, overall length and fitting orientation so hose and connection requirements can be reviewed together.
Assembly pressure limits, leak testing and any burst or pull-off validation are agreed for the selected hose-and-fitting combination.

Find the right hose for your cooling loop
Request specifications, check available sizes or discuss a sample. An existing part number, drawing or reference photo is a useful starting point.
Helpful details: hose ID / OD, coolant and concentration, working pressure, temperature, required length and quantity.
