PTFE Lined Reducing Flanges

As a reliable PTFE Lined Reducing Flanges Manufacturer, MVS Valves delivers high-performance flange solutions specifically engineered for corrosive, abrasive, or ultrapure applications. Our PTFE-Lined Reducing Flanges allow for smooth transitions between different pipeline diameters while maintaining full corrosion protection and secure sealing.

These reducing flanges are available in sizes ranging from ½″ to 24″ (DN 15–600) and pressure-rated for ANSI Class 150/300 or PN 10–25 systems. Designed to withstand challenging conditions, they operate reliably in temperatures between –40 °C and +230 °C, making them suitable for chemical processing, acid transfer, pharmaceutical production, and other demanding environments. All components are manufactured to ASTM F1545, ASME B16.5, and ISO standards, ensuring global quality compliance.

MVS manufactures PTFE Lined Reducing Flanges in a wafer-style design with threaded bolt holes and concentric bores. These flanges feature full PTFE or PFA lining, ensuring excellent chemical resistance and a leak-proof, bubble-tight connection. The lining extends seamlessly into the bore, safeguarding the transition point from corrosion and contamination. We offer both standard reducing flanges, which are readily available in stock, and custom-engineered variants tailored to specific customer specifications. Whether you’re handling hydrochloric acid, nitric acid, caustic soda, or any other aggressive media, our lined reducing flanges provide the long-lasting performance and reliability your process demands. When you need a secure and corrosion-proof solution for connecting pipelines of different sizes, trust MVS Valves—the trusted name in PTFE Lined Reducing Flanges Manufacturing.
