FEP Multi-Lumen Tubing Custom Dual-Lumen Triple-Lumen and Multi-Channel Fluoropolymer Tube for Chemical, Medical, Laboratory and Industrial Fluid Transfer

FEP Multi-Lumen Tubing

FEP multi-lumen tubing is a custom fluoropolymer tube containing two or more separate internal channels within a single outer profile.

Compared with using several individual tubes, a multi-lumen construction can simplify equipment routing, reduce installation space and keep multiple fluid, gas, sensing or control lines organized within one tube.

We can manufacture:

• FEP dual-lumen tubing
• FEP triple-lumen tubing
• FEP multi-lumen tubing
• Parallel-channel tubing
• Customized internal-channel tubing
• Asymmetric multi-lumen tubing
• Tubing with different channel diameters

The number, diameter, position and shape of the internal lumens can be developed according to the customer’s drawing, sample or application requirements.

FEP material provides good chemical resistance, a smooth non-stick surface, low moisture absorption and natural transparency. It is suitable for applications requiring visible fluid transfer, compact routing and multiple independent flow paths.
