Expanded ptfe tape  made of pure PTFE, can be widely used in the transport and sealing of industrial fluids. It is the most cost-effective alternative to sheet gasketing for large equipment flanges. Because it is a form-in-place gasket, so it nearly can be used in any sealing surface. Especially for the irregularities and damaged flange surface, expanded PTFE tape is the best choice.

Best properties
1. Easy to install
2. Low stress-to-seal
3. Can conform to any surface, including rough, pitted, scratched and damaged  surfaces.
4. Resistant to creep and cold flow
5. 100% expanded PTFE, has the same chemical inertness of pure virgin PTFE.
6. Unlimited Shelf Life
7. Over compression is no problem

Application 
PTFE expaned tape is especially suited for sealing flange connections, pipe systems, hydraulic and pneumatic systems, etc. In addition, it’s also ideal for seals in glass, enamel and plastic flanges, vessels and special shaped sealing surface.
PTFE expaned tape saves money and time. Since there is no scrap or waste, it costs less than other gasket materials. By using only a few sizes, large inventories of sheet gasketing and costly precut gaskets can be eliminated. Installation time is kept to a minimum since there are no templates, precutting or special fitting requirements.
