FEP Liquid Cooling Tubing is a fluoropolymer tube designed for transporting coolant in liquid cooling and thermal management systems. Made from fluorinated ethylene propylene (FEP), the tubing combines chemical resistance, a smooth inner surface, low moisture absorption, and good flexibility for routing coolant between system components.
FEP tubing is suitable for liquid cooling systems where the tube may come into contact with coolants, dielectric fluids, or other thermal management liquids. Its translucent appearance also allows visual observation of the fluid inside the line, which can be useful during installation, inspection, and maintenance.
JAIFUXIN manufactures FEP tubing for liquid cooling systems in custom inside diameters, outside diameters, wall thicknesses, and lengths according to equipment and coolant-loop requirements.

FEP Tubing for Liquid Cooling Systems
A liquid cooling loop transfers heat away from heat-generating components by circulating coolant through tubing, cold plates, heat exchangers, pumps, reservoirs, and other components.
FEP Liquid Cooling Tubing provides the fluid path between these components.
Typical connection points include:
- Cold plates
- Pumps
- Coolant reservoirs
- Heat exchangers
- Manifolds
- Valves
- Sensors
- Cooling distribution units
- Other fluid-control components
The tubing size should be selected according to the required flow rate, coolant, connection size, pressure, temperature, and equipment layout.
Why Use FEP for Coolant Tubing?
FEP combines several properties that are useful in liquid cooling systems.
Chemical Compatibility
FEP is resistant to a broad range of chemicals and fluids. This can be useful in cooling systems where long-term contact between the coolant and tubing material must be considered.
Compatibility should always be checked against the specific coolant formulation, additives, concentration, and operating temperature.
Smooth Internal Surface
The smooth internal surface of FEP tubing helps provide a clean fluid path and reduces areas where residues can adhere to the tube wall.
This is useful in cooling loops where maintaining a clean coolant circuit is important.
Translucency
Unlike opaque tubing materials, natural FEP tubing is translucent.
This allows operators to visually check the fluid line for:
- Coolant presence
- Air bubbles
- Discoloration
- Contamination
- Flow-related problems during system setup
Visual inspection does not replace flow, pressure, or leak monitoring, but it can make installation and troubleshooting easier.
Electrical Insulation
FEP is an electrically insulating fluoropolymer. This makes it useful for cooling systems installed around electrical and electronic equipment where non-conductive tubing material is preferred.
The electrical properties of the tubing should not be confused with those of the coolant itself; the complete system must be evaluated according to the coolant and electrical design.
Typical Applications
FEP Cooling Tubing can be used in thermal management systems for:
- Electronics cooling
- Semiconductor equipment
- Battery thermal management equipment
- Power electronics
- Energy storage systems
- Test and measurement equipment
- Industrial cooling equipment
- Laboratory cooling systems
- Temperature-control equipment
- Custom liquid cooling loops
The final tubing specification depends on the coolant and operating requirements of the system.
