Data Center Liquid Cooling Tube
China Super Tech Co., Ltd. develops and manufactures Data Center Liquid Cooling Tube using a multilayer barrier structure and low-ion-leaching materials, specifically designed for direct-to-chip liquid cooling, CDU coolant distribution, and rack-level cooling circuits in data centers. The product features low permeability, stable pressure resistance, antibacterial and anti-scaling properties, enabling long-term maintenance of coolant purity and stable flow. It is suitable for high-density server environments, helping customers reduce maintenance costs and improve the reliability of liquid cooling systems.
Product Introduction
Product Features
1.Multilayer Barrier Structure for Low Coolant Permeability
The tube wall uses an EVOH/PA composite barrier layer extrusion process. Its gas and liquid permeability coefficients are significantly lower than those of conventional single-layer EPDM tubing. This effectively prevents long-term evaporation of ethylene glycol solutions from causing concentration changes, while also preventing external oxygen from entering the tube and causing oxidation and corrosion of metal components. This is a key performance advantage that is difficult to achieve with conventional rubber hoses.
2.Low-Ion-Leaching Materials for Maintaining Cold Plate Cleanliness
The inner wall of the tube uses a specially formulated material with low calcium content and low metal-ion migration. This helps prevent material leaching from increasing coolant conductivity during long-term circulation, thereby reducing the risk of scaling and blockage in copper tubes and microchannels inside cold plates. This is particularly important for precision electronic cooling systems.
3.High-Strength Fiber Braided Reinforcement for Stable Pressure Resistance
The tube uses aramid fiber or stainless steel wire braided reinforcement combined with circular co-extrusion molding. The ratio between working pressure and burst pressure is controlled within a safe range, allowing the tube to maintain long-term sealing stability even under frequent connection and disconnection, vibration, and other rack operating conditions, while reducing the risk of leakage.
4.Good Flexibility for High-Density Routing
The tube wall thickness and hardness are optimized in combination to achieve a small minimum bending radius. The tube can be repeatedly bent and routed through confined rack spaces without collapsing or kinking, helping maintain stable coolant flow and avoiding increased local flow resistance.
5.Flame Retardant and Anti-Static Performance for Data Center Safety
The tube material incorporates halogen-free flame retardants and achieves a UL94 V-0 flame-retardant rating. It also provides anti-static performance to prevent static charge accumulation from causing electrostatic discharge damage to precision electronic components, supporting fire safety and electrostatic management requirements in data center facilities.
Product Applications

Direct-to-Chip Liquid Cooling for Servers
The tube is used to connect CPU/GPU cold plates with coolant distribution manifolds. Its low permeability and low-ion-leaching properties help maintain coolant quality during long-term circulation and keep cold plate heat transfer performance stable.
Rear Door Heat Exchanger (RDHx) Cooling Branches
The tube is used for coolant inlet and outlet lines connected to rear-door heat exchangers. Its good flexibility and small bending radius make it easier to organize piping within limited spaces without interfering with airflow inside the rack.
Direct-to-Chip Liquid Cooling for Servers
The tube is used as the coolant transfer line between the Coolant Distribution Unit (CDU) and server racks. Its pressure resistance and vibration resistance enable it to handle pressure fluctuations during parallel operation of multiple racks while reducing the risk of leakage at connection points.
Data Center Cooling Network Retrofit
The tube is suitable for upgrading and retrofitting liquid cooling systems in existing data centers. Lengths and connection fittings can be customized according to the actual piping layout, reducing the number of cutting and joining operations during installation and lowering the number of potential leakage points.
Customization Services
1.Customized Tube Diameter and Length
Different inner and outer diameters and complete tube lengths can be provided according to the customer's cold plate interface dimensions and rack layout. This reduces the number of on-site connection points and lowers the risk of leakage.
2.Flexible Connection Fitting Options
Various connection methods, including quick-connect fittings, threaded fittings, and clamp-type fittings, can be customized to match the interfaces of mainstream CDU and cold plate manufacturers and simplify customer installation.
3.Coolant Compatibility Customization
According to the customer's coolant, such as different concentrations of ethylene glycol, deionized water, or other cooling media, the inner-wall formulation and barrier-layer structure can be adjusted to ensure long-term compatibility and prevent material degradation.
4.Color Identification and Batch Certification Support
Tube colors can be customized according to cooling circuit functions to facilitate on-site identification and management. RoHS, REACH, and other environmental compliance documents and batch inspection reports can also be provided to support project acceptance.
China Super Tech Co., Ltd. integrates the above customization requirements into the same production batch through its in-house multilayer co-extrusion production lines and formulation R&D capabilities, avoiding compatibility issues caused by purchasing components from multiple suppliers.

FAQ
Will this Data Center Liquid Cooling Tube affect coolant purity?
+
-
No. The inner wall uses a low-ion-leaching formulation and does not release metal ions into the coolant during long-term circulation, helping prevent increases in conductivity that could lead to scaling or short-circuit risks in cold plates.
Can the tube's pressure resistance meet the requirements of multiple-rack parallel operation
+
-
Yes. The tube has a working pressure of up to 1.6 MPa and a burst pressure of at least 4.5 MPa, providing sufficient safety margin for pressure fluctuations during parallel operation of multiple racks.
Will long-term coolant use cause the concentration to decrease due to permeability
+
-
There will be no significant decrease. The multilayer barrier structure provides much lower permeability than conventional single-layer rubber tubing, helping maintain the concentration of ethylene glycol and other coolants over long-term operation and reducing the frequency of coolant replenishment.
Can the length and fittings be customized according to our rack interfaces?
+
-
Yes. China Super Tech Co., Ltd. supports customized tube lengths and connection fittings according to customer drawings and site requirements, reducing on-site cutting and connection points and lowering the risk of leakage after installation.
Does the tube meet fire safety requirements for data center facilities?
+
-
Yes. The tube achieves a UL94 V-0 flame-retardant rating and provides anti-static performance, supporting fire safety and electrostatic management requirements in data center facilities and around electronic equipment.
