As server power density climbs, air cooling alone can no longer carry the heat away from modern racks. Direct-to-chip and rear-door heat exchangers move that heat into a liquid loop — and that loop is only as reliable as the hose carrying the coolant. A single leaking joint inside a rack can take down a whole cabinet, so the hose is no longer a commodity component. It is part of the thermal safety system.
YIBO manufactures liquid cooling hose specifically for this job: server and rack cooling loops, CDU connections and manifold runs where space is tight and downtime is expensive. It is built with a low bend radius so it can be routed through compact equipment spaces without kinking, and it is engineered to resist leakage at the connection points that see the most mechanical stress.
Inside a rack there is rarely a straight run. Hose has to turn sharply around power supplies, cable trays and chassis edges. Our construction keeps a low bend radius, which means the hose can follow those tight paths without collapsing or kinking — a kinked hose restricts flow, raises pump load and creates a hot spot exactly where you cannot afford one.
Leakage is the single biggest risk in a liquid cooling loop. Our hose is built to resist leakage at the joint and along the body, with a tube and cover compound selected for repeated thermal cycling. Combined with properly crimped fittings, this gives a connection that holds through the temperature swings a data center sees between idle and full load.
Electrical equipment and coolant in the same enclosure is a combination that demands care. Our liquid cooling hose uses a flame-retardant cover compound, so that in the event of a fault the hose does not add fuel to the situation. This matters for both equipment protection and for meeting the fire-safety requirements of the facility itself.
The inner tube is made from black EPDM synthetic rubber, a compound widely used in cooling circuits because it resists the degradation that many elastomers suffer when exposed to water-glycol coolant over long periods. The reinforcement layer — one or two layers of synthetic fiber braid — gives the hose the pressure capability the loop requires while keeping it flexible enough to route by hand.
The black EPDM cover is compounded for weather, abrasion and ozone resistance. In practice this means the hose keeps working in plant rooms, containerized data centers and outdoor cooling skids where UV, dust and mechanical rubbing are all present.

Four things determine whether a hose is right for a given loop:
Can the hose be routed around tight corners inside a rack?
Yes — a low bend radius is one of the reasons this hose exists. It is designed for the compact equipment spaces found in server and rack cooling, where a straight run is rarely available.
Do you supply complete assemblies, or hose only?
Both. Many customers buy crimped assemblies so that the hose-to-fitting joint is made under controlled conditions rather than on site. If you prefer to crimp locally, we can supply hose by the metre.
Can you produce to our drawing or sample?
Yes. Diameter, length, fitting type and assembly layout can all be made to your drawing or a physical sample. Send us the specification and we will confirm feasibility and lead time.
What is the minimum order quantity?
MOQ starts from 100 m. For assembly work it depends on the fitting type and configuration — ask us and we will give you a straight answer rather than a generic one.
YIBO is a manufacturer, not a trading company. We produce hydraulic hose, high-pressure oil hose and industrial hose, and we are a National High-Tech Enterprise as well as an SRDI (Specialized, Refined, Differential, Innovative) SME of Henan Province.
Send us your loop parameters — coolant type, flow rate, working temperature, the tightest bend in your routing and the fitting you intend to use — and we will come back with a specification and a price within the hour.
