Teflon Bellow Mechanical Seal

The Teflon (PTFE) Bellow Mechanical Seal is built for highly corrosive and aggressive media where standard elastomers fail. With superior chemical resistance and a non-metallic, non-stick surface, it is ideal for handling acids, alkalis, solvents, and food-grade fluids in demanding industrial applications.
