Why FEP and PFA Tubing Excel in Chemical and High-Purity Environments
When you're working in semiconductors, pharmaceuticals, lab analysis, or medical devices, your tubing has to handle harsh chemicals, extreme temperatures, and zero contamination. That's where FEP and PFA tubing shine. These fluoropolymer tubes offer rock-solid chemical resistance, full biocompatibility, and crystal-clear transparency—perfect for moving fluids or gases without any risk of reaction or failure.
Introducing FEP Tubing: Versatile, Transparent, and Easy to Process
FEP—sometimes called F46—is basically PTFE you can actually work with. It melts, welds, and reshapes without losing any of the legendary inertness that makes fluoroplastics famous.
What Makes FEP Tubing Special
- Weld it, flare it, rework it – Build custom setups fast.
- Runs from -200°C to +200°C – Stays soft in liquid nitrogen and holds up under heat.
- Laughs at chemicals and UV – Acids, solvents, and sunlight? No problem.
- See-through and body-safe – Great for medical lines and flow monitoring.
- Shrinks at low heat – Wrap delicate electronics without cooking them.
Quick Tip: Grab FEP heat shrink to shield sensors or fiber optics. It tightens up gently—no melted parts.
Introducing PFA Tubing: Built for Heat, Purity, and Tough Jobs
PFA takes everything FEP does and cranks the heat tolerance way up. It flows easier during manufacturing but still runs nonstop at 260°C, making it the go-to for steam, hot acids, or semiconductor wet benches.
What Sets PFA Tubing Apart
- Nonstop at 260°C – Steam lines and boiling chemicals don’t faze it.
- Weldable, ultra-pure grades – Meets USP Class VI for pharma and chip fabs.
- Blocks gas leaks cold – Vapor and permeation stay out.
- Glass-clear walls – Watch your fluid move in real time.
- Safe for bodies and food – Zero toxicity, full biocompatibility.
- Handles hot concentrated acids – No breakdown, even under pressure.
- Low dielectric (2.1) – Ideal for high-frequency cables.
Where You’ll Find FEP and PFA Tubing in Action
- FEP: LCD fabs, fiber optic jackets, heat exchangers, reagent lines, corrosive fluid transfer, submersible motors, AC wiring harnesses.
- PFA: Semiconductor etch baskets, pump and valve liners, medical transfer tubing, pharma process lines, high-temp steam distribution.
