Ptfe gaskets - Import export

Due to the wide range of different designs, perfectly suitable PTFE seals are available for every application. The PTFE gaskets from billi are characterized by high dielectric strength, excellent electrical insulation properties and a low thermal conductivity. All items are manufactured with a high processing quality. Discover the various PTFE gaskets in our online catalogue and order the right products for your application directly from billi. Depending on the respective requirements, different PTFE seals are suitable for you: Our comprehensive range includes, for example, PTFE thread sealing tapes with a temperature resistance of -200°C up to +260°C. The PTFE tapes are both, odourless and insoluble. In addition, the PTFE thread sealing tapes have a particularly low coefficient of friction, which improves their performances. We also offer PTFE cord with a pressure resistance of up to 10 bar. Possible applications include valves as well as piston and centrifugal pumps.
