National Fluoromers is a trusted manufacturer, supplier, and exporter of PTFE bellows, designed to absorb mechanical vibrations, axial movement, and thermal expansion in pipeline systems. These bellows are ideal for chemically aggressive or high-purity applications, providing long-term protection against leaks, stress, and corrosion.

With their excellent flexibility, non-stick properties, and thermal resistance, our PTFE bellows are widely used in chemical plants, food processing units, and pharmaceutical production lines.

what is a PTFE bellow?

A PTFE bellow is a flexible, corrugated component fabricated from polytetrafluoroethylene that serves as an expansion joint or protective cover in piping and mechanical systems. These bellows accommodate movement in multiple directions—axial, lateral, and angular—while isolating components from vibration and mechanical stress.

PTFE bellows are also used as flexible connectors, dust covers, or expansion compensators where harsh chemicals, high temperatures, or hygienic standards demand a non-metallic alternative.

key features
  • Superior chemical resistance: Withstands acids, alkalis, solvents, and reactive gases.
  • Highly flexible design: Absorbs multi-directional movements and vibrations.
  • Thermal stability: Reliable from –200°C to +260°C.
  • Non-stick surface: Prevents scale buildup and contamination.
  • Hygienic & non-toxic: Suitable for food, pharmaceutical, and cleanroom use.
  • Available in multiple convolution designs: Tailored to your movement needs.
