Description
Fobos Polymer supplies custom PTFE multi-lumen tubing for medical devices, catheter components, guidewire access, fluid transfer, and precision multi-channel applications. Our multi-lumen tubing features multiple channels within a single outer diameter, enabling different functional paths for guidewires, fluids, gases, instruments, or electrical insulation in compact medical assemblies.
Compared with single-lumen PTFE tubing, multi-lumen designs improve space efficiency and functional integration. They are widely used in catheter components, minimally invasive device assemblies, guidewire access systems, diagnostic equipment, and precision fluid transfer applications.
Fobos manufactures custom PTFE multi-lumen tubing according to customer drawings, samples, or project requirements. The number of lumens, lumen size, outer profile, wall thickness, color, and surface treatment can all be customized.

Material Advantages
PTFE offers excellent chemical resistance, low friction, high and low temperature resistance, weather resistance, non-stick performance, and dielectric insulation. These properties make PTFE multi-lumen tubing suitable for applications where multiple channels must remain stable, clean, and low-friction inside a compact structure.
The low coefficient of friction supports guidewire movement and smooth fluid transfer. PTFE’s chemical resistance allows the tubing to withstand many chemicals, solvents, acids, alkalis, and organic media. Its excellent dielectric properties also make it suitable for insulation-related medical and precision equipment applications.

Fobos Production Strength
Fobos Polymer focuses on medical polymer tubing and precision PTFE components. For multi-lumen tubing projects, we support technical discussion from early drawing review to sample development and bulk production.
Our team can help evaluate lumen structure, OD/ID requirements, tolerance, surface treatment, cutting method, and packaging. For applications that require bonding, etched PTFE surface treatment can be discussed to improve assembly compatibility.
Fobos is supported by SUKO Group’s long-term experience in PTFE processing and polymer machinery. SUKO Group develops PTFE extrusion, forming, and sintering equipment in-house, giving our team stronger understanding of PTFE material behavior and process control. This equipment-level experience helps support stable production of custom PTFE tubing and complex polymer structures.
Case and Project Experience
Fobos has supported medical and precision tubing projects involving catheter-related PTFE tubing, thin wall tubing, multi-channel structures, and custom polymer components. Customers often require smooth inner surfaces, tight dimensional control, stable lumen geometry, and clean packaging for device assembly.
For multi-lumen PTFE tubing, common customer requirements include guidewire channels, separate liquid or gas paths, compact OD design, etchable surface for bonding, and customized color identification. Fobos can assist from prototype sampling to repeated production based on the customer’s drawing and application needs.
FAQ
Q1: What is PTFE multi-lumen tubing?
A: It is a PTFE tube with multiple internal channels under one outer diameter, allowing different paths for guidewires, fluids, gases, or other functions.
Q2: Can you customize the lumen layout?
A: Yes. The number of lumens, lumen size, outer shape, and tube profile can be customized according to drawing or sample requirements.
Q3: What shapes can be produced?
A: Round, oval, T-shaped, triangular, and other custom outer profiles can be discussed by project.
Q4: Can the surface be bonded?
A: PTFE is naturally difficult to bond, but etched surface treatment can be provided to improve bonding performance.
Q5: What tolerance can you achieve?
A: The minimum tolerance can be accurate to ±0.02mm depending on size, structure, and production requirements.
Q6: Is it suitable for medical devices?
A: PTFE multi-lumen tubing can be used in medical device and catheter-related applications. Final suitability depends on the customer’s testing, validation, and regulatory requirements.
