The PTFE Check Valves from Paul Tube Fittings are made using virgin PTFE, celebrated for its exceptional chemical inertness, non-stick surface, and broad thermal resistance (-200°C to +260°C). PTFE boasts excellent dielectric properties, low permeability, and remains unaffected by most acids, bases, and solvents. Although PTFE has moderate mechanical strength (~20–35 MPa tensile strength), it excels in sealing, corrosion resistance, and dimensional stability. These check valves are lightweight, non-metallic, and require no maintenance, providing dependable backflow prevention in ultra-clean and chemically aggressive environments across various industrial and laboratory systems.
