PTFE Lined Reducing Flange
PTFE lined reducing flanges are corrosion-resistant components designed to connect pipes of different diameters while ensuring safe handling of aggressive or high-purity fluids. With a robust steel flange and a chemically inert PTFE lining, they prevent corrosion, leakage, and contamination. These flanges provide a secure, reliable connection and are widely used in chemical, pharmaceutical, and industrial fluid-transfer systems.
Key Features:
- Reliable size adaptation
- High chemical resistance
- Leak-proof PTFE lining
- Strong steel construction
