monoFlon® Joint Sealant Style F

expanded PTFE Joint Sealant

monoFlon® Joint Sealant gasket tape is made from pure, 100% expanded PolyTetraFluoroEthylene (ePTFE).

During pressing, the universal joint sealant adapts to the sealing surface and forms a thin, tear-resistant sealing film. The result is a reliable sealing connection that is resistant to aggressive media and seals permanently.

Even with large flanges, complex geometries and damaged surfaces – simply peel off the backing paper, stick the gasket onto the cleaned sealing surface, overlap the ends, close the sealing joint – done.

monoFlon® Style F – ECO is the self-adhesive economical sealing solution for all standard applications.

monoFlon® Style F – PRO is provided with a high performance hotmelt adhesive which ensures optimum adhesion to the component surface and prevents unnecessary contamination of the application.

monoFlon® Style F – PRO GMP meets the requirements for use in the food industry according to EC 2023/2006.

monoFlon® Style R is an adhesive-free version with a round cross-section.
