PTFE bellow seals are designed for extremely corrosive chemicals, including concentrated acids, salts, strong oxidising & reducing agents, and chemically active organic compounds. All components which come in contact with the liquid being sealed are made of chemically inert material. Metallic components clamping ring and springs are located outside the media. In this seal series Glass filled PTFE face is composite moulded with highly flexible PTFE bellows.
Application
Used in acids, alkalis & extremely corrosive services.
