Fluoropolymer tubing for the demanding applications standard PU and nylon cannot serve, pharmaceutical, food contact, laboratory, semiconductor, aggressive chemical service. FEP (fluorinated ethylene propylene) is the more flexible, easier-to-handle fluoropolymer and the usual choice for tubing; PTFE (polytetrafluoroethylene) is stiffer and used where its higher temperature ceiling or surface properties are needed. Both are chemically near-inert (resist solvents, acids, bases that would dissolve a thermoplastic), hold a very wide temperature range, are UV-stable for indefinite outdoor service, and have transparent walls for visual flow checks. Trade-offs are real: lower working pressure than PU or nylon at the same OD, several times the cost, project-based stocking rather than deep shelf. Specified when chemistry, purity requirement, temperature, or UV exposure leaves no thermoplastic alternative, not as a general upgrade.
When FEP/PTFE fluoropolymer is the right call, and when to spec something else. Review the points below.
Inert to concentrated sulfuric, nitric, HF, HCl, NaOH, KOH; aromatics, chlorinated solvents, ketones, alcohols. The only polymer family that survives sulfuric-acid delivery, solvent manifolds, semiconductor wet-process.
FEP service to +400°F continuous; PTFE to +500°F. Both UV-stable and ozone-stable indefinitely, the polymer for hot-process, steam-line proximity, decade-plus outdoor.
Certifications against FDA 21 CFR 177.1550, USP Class VI, ASME-BPE, EU 10/2011. The only polymer that passes bioreactor sample loops, WFI plumbing, GC/mass-spec sample paths.
FEP: more flexible (8-12× OD bend radius), easier routing, usual choice. PTFE: stiffer (12-15× OD), only where temperature exceeds FEP''s 400°F or surface properties demand it. Cleanroom-extruded PFA for sub-ppb semi fab.
Several times the cost per foot without proportional value, fluoropolymer is chemistry-and-regulatory specification, not a quality upgrade. → Step down to PU for standard pneumatic at 1/10th the cost.
Soft fluoropolymer extrudes past generic PTC collets; 6mm FEP rates only 100-150 PSI ambient. → Pair with compression or flare fittings (instrumentation stainless tube fitting) for sustained pressure or vibration-prone runs.
Over-spec where chemistry is petroleum-based, not aggressive. → Step down to PA12 nylon at 10× lower cost per foot, right for CNC coolant, lubrication, fuel, machine plumbing.
