Cooling Hose Assembly
Configured around your hose, end connections and operating conditions.
Bring the hose, mating interfaces and verification requirements into one specification. Discuss custom lengths, end fittings and sample assemblies for rack and equipment cooling loops.
One assembly · three connected choices
Specify the connection from end to end.
A complete drawing links both interfaces to the hose, length and routing requirements.
End A · The first interface
Plug / socket or threaded end. Define the mating component, sealing method and fitting orientation.
Hose · The flexible path
Define material, bore, overall length, tolerance and bend layout around the available space.
End B · The second interface
Confirm the return interface independently. End A and End B do not need to be identical.
Specification review
Build a clear assembly brief.
Share what is known. The remaining details can be confirmed during review.
Ratings apply to the validated hose-and-fitting combination. A hose component rating alone does not establish the rating of the complete assembly.
| Parameter | What to specify |
|---|---|
| Hose material & bore | Specified hose compound and construction; inner diameter, outer diameter and any approved hose brand or part number. |
| Length & routing | Overall assembly length and reference points, tolerances, bend layout and available installation space. |
| End A / End B | Mating interface, plug or socket, thread standard, sealing method and fitting orientation for each end. |
| Coolant | Fluid name, formulation or datasheet, concentration and any required material-compatibility evidence. |
| Flow & pressure drop | Target flow and maximum allowable pressure drop, with coolant and temperature stated. Define whether the limit covers the full assembly and mating connectors. |
| Pressure & temperature | Working pressure, pressure transients, continuous temperature and any short-term excursions. |
| Brand / approved vendor list | Designated hose and connector brands, approved part numbers and whether alternatives may be proposed. |
| Verification requirements | Leak and pressure-hold checks; burst, pull-off, flow-pressure-drop or other validation where specified and agreed. |
| Cleanliness & delivery | Internal cleanliness criteria, inspection method, end caps, individual packaging and identification requirements. |
| Quantity & documentation | Sample and batch quantities, drawing revision, inspection records and delivery requirements. |
Configuration & delivery
Agree the details before sampling.
End fitting & crimping review
Agree the hose, insert and ferrule combination, fitting orientation and assembly method. A component substitution can require a renewed process and verification review.
Flow & pressure-drop review
Share target flow and allowable pressure drop. Review available performance data and agree whether a flow-pressure-drop test is required for the proposed assembly.
Cleanliness & traceability
Define cleaning, particle or residue criteria, end protection, packaging and batch identification before samples are approved.
Sample verification
Define the checks. Agree the evidence.
Test scope and acceptance criteria are confirmed for the selected assembly before work begins.
Leak & pressure hold
Test medium, pressure, duration, leakage limit and inspection record.
Mechanical validation
Burst and pull-off requirements, sample quantity and acceptance criteria, where specified.
Flow performance
Target flow, pressure-drop boundary, coolant and test temperature.
Cleanliness & records
Inspection method, allowed contamination, end protection and traceability.
Verification scope is project-specific. Test availability, responsibility and any external testing are confirmed before quotation.
Applications
Designed into the cooling loop.
Rack-to-equipment connections
Flexible supply and return connections selected around rack layout, mating hardware and service access.
Server & cold-plate circuits
Compact assemblies where bend radius, connector envelope and pressure-drop allowance need to be reviewed together.
Equipment-internal circuits
Connections within liquid cooling equipment, with the assembly specification matched to the intended circuit.
Have a designated brand or an existing BOM?
Share your approved vendor list and mark whether alternatives are permitted. We can review sourcing and assembly requirements against the same brief.
