A PTFE-lined flanged metal hose is a specialized engineering solution designed to handle the most aggressive chemical media while maintaining the flexibility and pressure resistance of a standard flanged metal hose. It features a core construction where a corrugated metal hose (typically stainless steel) provides structural strength and flexibility, and is internally lined with a seamless layer of Polytetrafluoroethylene (PTFE).

The PTFE lining offers exceptional chemical inertness, resisting virtually all aggressive acids, bases, and solvents. It also provides a non-stick, ultra-smooth surface that minimizes material buildup and allows for easy cleaning. The flanged ends ensure a robust, leak-proof connection suitable for high-pressure and high-temperature applications.

This combination makes PTFE-lined hoses ideal for critical applications in the chemical processing, pharmaceutical, semiconductor, and other industries where transferring highly corrosive or ultra-pure fluids is necessary.
