Teflon Tube for Automotive and High-Temperature Cable
PTFE sleeving for engine-bay and powertrain wiring. Engine-bay and powertrain wiring runs hot and against fluids. PTFE sleeving protects it across the temperature range without hardening. We supply cut-to-length and spooled PTFE sleeving matched to the wire gauge and routing. Yes. PTFE resists oil, fuel and most fluids at engine temperatures. We confirm the specific fluid if needed.

Applications by industry
- Automotive engine-bay high-temperature cable sleeving
- Turbo and exhaust-adjacent harness protection
- Wiring near brakes, manifolds and hot sensors
- EV battery and BLDC motor lead insulation
- Chemical and brake-fluid resistant sleeving
- High-flex, low-friction cable conduit in vehicles
Why PTFE for this application
PTFE survives engine-bay heat and aggressive fluids, stays flexible for routing and adds low friction where a routed harness would otherwise abrade.
Confirm max service temp vs the exact hot spot (turbo/manifold can exceed PTFE soft spot). Stiffness at small bend radius may need oversized tube.
Standards: ISO 6722, SAE J1654, ASTM D3294.
Feature and remaining-wall review
Teflon Tube is sintered to size on ID and OD, then CNC turned for ends, slots and holes. PTFE needs sharp tooling to stop chatter. We review feature depth, edge distance and remaining wall on Teflon Tube against the critical geometries; capability comes from your drawing, not 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
