DATA CENTER LIQUID COOLING HOSE

Data Center Liquid Cooling Hose

Data center liquid cooling hose is the line component of cold-plate and immersion cooling systems: it delivers coolant to the server end and brings heat back to the cooling end. Unlike a conventional hydraulic hose, the core requirement of a liquid-cooling line is long-term leak-free performance — a single leak can reach the server, power supply and cabinet.

Construction

• Inner Tube: Black EPDM synthetic rubber.
• Reinforcement: One or two layers of synthetic fiber braid.
• Outer Cover: Black weather-, abrasion- and ozone-resistant, V0 flame-retardant EPDM synthetic rubber.

Working Temperature: -40°C to +120°C (-40°F to +248°F).

Why EPDM and V0 Flame Retardant

The inner tube is black EPDM synthetic rubber. EPDM is compatible with many common coolants, resists ozone and aging, and does not react adversely with metal lines or seals. The black formulation also lowers in-line light absorption, making liquid level and bubbles easier to inspect visually.

The reinforcement offers one or two synthetic-fiber braid layers depending on pressure class and routing: straight routing with small pressure fluctuation can use a single layer; circuits with pressure fluctuation, limited bend radius or long spans should use two layers for more reliable pressure capacity and shape-holding.

The outer cover is black weather-, abrasion- and ozone-resistant, V0 flame-retardant EPDM. V0 is the key indicator of this layer — it strictly controls the material's burning behavior under flame. It cannot remove fire risk, but in a high-density machine room flame retardancy is a mandatory baseline.

How to Select

• Prioritize leak-risk control. A liquid-cooling system should treat leak prevention as goal one. Define pressure class, pulse frequency and interface form; confirm the coupling and seal plan are compatible with the media. In high-value cabinet zones add leak detection and redundancy.
• Set reinforcement by space limits. Cabinet space is extremely tight; the hose must turn within narrow gaps. Ample, straight space can use a single layer; connecting from the CDU into the cabinet or crossing narrow slits should use two layers to keep long-term shape stable.

Frequently Asked Questions

What does V0 flame retardant mean?
It describes a grade where the material's burning behavior under flame is strictly controlled. Flame retardancy cannot prevent ignition, but it slows the burn rate when fire occurs, buying time to respond. In a high-density machine room it is a necessary baseline.

What is the risk if the hose leaks?
Once a liquid-cooling line leaks, coolant can reach the server, power supply and cabinet structure. Live equipment contacting liquid risks short circuit and damage, so leak prevention outranks every other metric and must be secured across material, sealing and leak detection.

Why not substitute a ordinary hydraulic hose?
An ordinary hydraulic hose may lack the flame-retardant grade liquid cooling requires, and may not be long-term compatible with the coolant used. Substitution must be verified item by item; appearance alone is not a basis to replace.

Does it need replacement over time?
Check periodically rather than waiting for a leak. Watch the outer cover for bulges, cracks, hardening or deformation, and the joints for seepage. A machine-room environment is stable, so anomalies are hidden — periodic checks matter.

Why Yibo

Yibo Technology focuses on hydraulic, high-pressure and industrial hose manufacturing with complete in-house production from raw material to finished product. For data-center liquid cooling, where leak prevention and flame retardancy are both explicit requirements, we give advice based on coolant type, pressure class, space limits and machine-room environment rather than simply quoting the highest specification. We also supply quick-connect fitting series — focused on safe, simple connection, leak-proof design, high flow and resistance to mechanical stress — and stainless rigid-pipe with corrugated-hose assemblies for cooling systems. Tell us the coolant, pressure and layout, and we match the right structure. Small trial orders and volume customization are both supported.
