- Sensor and probe cable covering in medical devices
- Low-friction, radiopaque-friendly catheter backer
Why PTFE for this application
PTFE's smoothness, biocompatibility profile and kink-resistant thin wall make it a standard liner for catheters and device leads, provided the medical-grade raw material and cleanroom processing are used.
Medical use requires validated raw-material lot, traceability and cleanroom build; confirm FDA 21 CFR / ISO 10993 compliance before quoting device use.
Standards: ISO 10993 (biocompatibility), FDA 21 CFR 177.1550, USP Class VI.
Feature and remaining-wall review
ID/OD sintered to size; CNC turning for ends, slots and holes. PTFE requires sharp tools to avoid chatter. Review feature depth, edge distance and remaining wall against critical geometries. Capability is confirmed on your drawing, not from a blanket tolerance.
Inspection and traceability
We state the control plan with you. Batch traceability links raw material lot to finished part.
- First-article inspection (FAI) per your plan
- In-process dimensional checks at every station
- Batch certificate of conformance (COA) supplied on request
- Lot traceability to incoming material certificate
- Dielectric strength and insulation resistance testing available on request

Common questions
Is PTFE chemically inert?
Yes. PTFE resists all common acids, bases, solvents and fuels except molten alkali metals and fluorine at elevated temperature. No post-processing needed for chemical resistance.
What tolerances can you hold on PTFE tubing?
ID/OD ±0.05 mm on standard sizes; tighter tolerances available with grinding. PTFE is sized by sintering, so critical dimensions are best held by finish grinding after forming.
Can PTFE be threaded or machined?
PTFE can be CNC-turned for ends, slots and holes using sharp, low-speed tools to avoid chatter. Threads are best formed by machining rather than rolling.
Do you supply material certification for PTFE?
Yes. Each batch includes a material COA. First-article inspection and dielectric strength testing are available per your specification.
Do you keep lot records for devices?
Yes. Each batch includes a material COA. First-article inspection and dielectric strength testing are available per your specification.
