Teflon (PTFE) Heat-Shrink Tubing for High Temperature and Chemical Duty
Shrink PTFE for chemically aggressive and high-temperature service. PTFE shrink tubing serves where nothing else survives: continuous heat to ~260 degC and almost total chemical resistance. We supply it for sensor, lab and process duty. Expanded (FEP-like recoverable) PTFE is used where a true recovery is needed; we match the grade to the process fluid and temperature. PTFE leads on temperature an

Applications by industry
- High-temperature and chemical-duty wire sleeving
- Semiconductor and lab instrument cable protection
- Heater and thermocouple lead insulation
- Capacitor and coil lead isolation tubing
- Low-friction conduit for moving wires
- Tight-diameter shrink over sensors and probes
Why PTFE / FEP heat-shrink for this application
PTFE shrinks over wires to give durable high-temperature, chemical-proof insulation with low outgassing for instruments that other polymers can't survive.
Shrink temperature is high; protect adjacent components. FEP shrinks easier than PTFE — confirm which your duty actually needs.
Standards: UL 224, ASTM D3294, MIL-I-23053 (PTFE shrink class).
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.
PTFE shrink vs FEP shrink?
Yes. Each batch includes a material COA. First-article inspection and dielectric strength testing are available per your specification.
