PTFE Multi‑Lumen Medical Tubing – 1 Large Center + 5 Small

Description

Product Description

This PTFE multi‑lumen tubing features a custom‑designed cross‑section with one central large lumen and five surrounding smaller lumens, offering a dedicated primary working channel alongside multiple auxiliary ports for guidewires, fluid delivery, drug infusion, or pressure monitoring – all within a single outer diameter.

Manufactured from medical‑grade PTFE, this tubing is engineered for demanding medical device applications requiring high purity, biocompatibility, and reliable performance. The overall shape can be customized to meet specific design needs, including but not limited to round, oval, T‑shaped, triangular, or other geometries.

Key Features

• High & Low Temperature Resistance – Operates continuously from ‑180°C to +250°C, and maintains 5% elongation even at ‑196°C.

• Chemically Inert – Resistant to strong acids, alkalis, solvents, water, and most organic chemicals.

• Excellent Weather Resistance – Outstanding aging resistance compared to other plastics.

• Low Friction Coefficient – One of the lowest friction materials available, ensuring smooth device movement.

• Non‑Adhesive Surface – Low surface tension prevents adhesion of any substance.

• Superior Dielectric Insulation – Ideal for electrical and sensor applications.

• Uniform Inner & Outer Diameter – Precision extrusion ensures consistent dimensions.

• Ultra‑Strict Tolerances – Minimum accuracy up to ±0.02mm.

• Etchable Surface – Can be chemically etched for bonding to other components.

• Sterilization Compatibility – Suitable for steam, ethylene oxide (EtO), and dry heat sterilization.
