Dubai, UAE-headquartered AL Jazeera PTFE is a high-quality PTFE Lined Expansion Bellows manufacturer with state-of-the-art flexible solutions to piping systems requiring chemical resistance as well as motion absorption. Its expansion bellows are developed for thermal expansion, vibration, and misalignment in hostile chemical services. We produce different types such as single convolution, multi-convolution, and universal PTFE lined bellows, with the possibility of flanged, threaded, or custom end connections. Designed for performance and longevity, these bellows are suitable for applications in chemical processing, pharmaceuticals, water treatment, and high-purity fluid transfer systems.
A PTFE Lined Expansion Bellow is a flexible coupling employed in piping to take up thermal expansion, vibration, and misalignment while offering superior resistance to corrosive chemicals. The PTFE (Polytetrafluoroethylene) internal lining isolates the process fluid from the metallic body, maintaining long service life even in harsh environments. These bellows play a key role in systems processing acids, solvents, or high-purity fluids and are used extensively across the chemical, pharmaceutical, and wastewater sectors due to their high reliability and minimal maintenance requirements.

PTFE lining increases resistance to chemical corrosion, extending the lifespan of the expansion bellow.
Allows for reliable movement and compensation of thermal expansion or contraction without damage.
Withstands a broad temperature range, making it suitable for extreme environments.
PTFE’s non-stick properties reduce buildup, minimizing cleaning and maintenance needs
It accommodates thermal movement, vibration, and misalignment within corrosive piping systems.
Single convolution, multi-convolution, and universal styles with differing end connections.
Generally resists temperatures between -30°C to +200°C and pressures up to 10 bar, depending on design.
Chemical processing, pharmaceuticals, petrochemicals, food processing, and wastewater treatment.
We are the leading Manufacturer and Supplier of PTFE Lined Pipe, Fittings, Flanges, Spool and Valves in Dubai, UAE.
