Liquid cooling tubing
Liquid cooling tubing is selected by coolant compatibility, pressure, temperature, bend radius, cleanliness and fitting method. This guide helps sourcing, electrical and thermal engineers compare PTFE, silicone rubber, PA and PU tubing for data centers, EV battery systems, inverters, charging equipment and industrial power electronics.

The first decision is not only the tubing material. The buyer should confirm coolant chemistry, concentration, working temperature, operating pressure, burst pressure target, fitting style and service environment. Water-glycol, dielectric fluid and other coolants may require different validation plans.
For data centers and power electronics, stable dimensional control, cleanliness, leakage risk and batch traceability are often as important as headline temperature resistance.
| Material | Typical reason to consider | Selection caution | Related page |
|---|---|---|---|
| PTFE tubing | Chemical resistance, low friction, clean fluid passage and stable dielectric behavior. | Confirm bend radius, fitting grip and wall grade for pressure needs. | PTFE tubing |
| Silicone rubber tube | Flexibility, soft connection and thermal aging resistance in suitable fluid systems. | Confirm coolant compatibility, permeability and clamping method. | Silicone rubber tube |
| PA tubing | Dimensional stability and routing for pneumatic or fluid lines where stiffness is useful. | Check impact, hydrolysis and coolant compatibility. | PA / PU tubing |
| PU tubing | Flexible routing where repeated bending and compact installation matter. | Validate long-term coolant and temperature exposure. | PA / PU tubing |
Before sample approval, build a test plan around working pressure, burst pressure, leak test method, thermal aging, coolant immersion, low-temperature flexibility, bending radius, compression set, fitting pull-off force, cleanliness and packaging.
If the cooling line passes near busbars, motors, transformers or high-temperature wiring, use routing protection and electrical insulation sleeves in the same design review.
Data center cold plates, CDU auxiliary lines, EV battery thermal management, inverter cooling, charging equipment, industrial power modules, medical equipment and precision machinery may all use liquid cooling tubing, but each application has different failure modes.
WCW Flex can review drawings, tubing size, fitting method, coolant condition, sample quantity and packaging so the quotation matches the real production scenario.
PTFE, silicone rubber, PA and PU tubing can all be considered depending on coolant chemistry, temperature, pressure, bend radius, cleanliness and assembly method.
Provide coolant type, working temperature, pressure, burst pressure target, bend radius, fitting method, ID, OD, cleanliness requirement and validation standard.
Usually no. Data center, battery, inverter and charging applications may use different tubing or protection materials based on fluid, thermal and mechanical risk.
Send coolant type, tube size, pressure, temperature, fitting method, sample schedule and expected annual demand. WCW Flex will help compare material options.
