A PTFE convoluted hose features a corrugated (spiral or annular) PTFE inner tube instead of a smooth bore.
The convolutions make the hose far more flexible than smooth bore PTFE, allowing tight bend radii and better vibration absorption.
It is highly resistant to chemicals, temperature extremes, and sticking or contamination, making it suitable for demanding fluid transfer applications.
Inner Tube
Virgin PTFE resin (FDA-approved for food contact if required).
Convoluted profile for flexibility and kink resistance.
Reinforcement Options
Stainless steel wire braid (SS304 or SS316) for pressure support.
Polypropylene or PVDF braid for non-metallic applications.
Outer Cover (Optional)
Silicone, EPDM, or PVC jacket for added abrasion and weather protection.
Size Range: 1/4" to 6" (DN6 – DN150)
Working Pressure: Up to ~100 bar (varies by diameter and braid type).
Temperature Range: –70 °C to +260 °C (–94 °F to +500 °F)
Standards: Can meet FDA, EN 16643, ATEX, and ISO 1307.
Maximum Flexibility – tighter bend radius than smooth bore PTFE.
Chemical Inertness – compatible with almost all fluids, gases, and vapors.
Non-stick & Low Friction – resists build-up and makes cleaning easy.
Thermal Stability – withstands wide temperature swings without degradation.
Customizable – available with conductive PTFE liners to prevent static build-up in flammable media transfer.
Chemical Transfer – aggressive acids, alkalis, and solvents.
Food & Beverage – transport of viscous syrups, sauces, and powders.
Pharmaceutical & Biotech – sterile or high-purity processing lines.
Paints, Inks & Coatings – solvent and pigment transfer.
Cryogenic Liquids – oxygen, nitrogen, argon at low temperatures.
Industrial Gases & Steam – safe high-temp or low-temp service.
Greater flexibility – easier routing in tight spaces.
Better vibration resistance – ideal for moving equipment.
Handles suction/vacuum service with proper braid reinforcement.
Lightweight while still offering high chemical and temperature resistance.
