![Junta plana SIGRAFLEX® MF con borde interior](https://wsrv.nl/?q=50&bg=%23f8f9fa&dpr=1&output=jpg&url=https%3A%2F%2Fatropim.idt-gaskets.com%2Fupload%2Fthumbnails%2F06lsx%2Fxjzn3%2F8tonu%2F3itw6%2Fzwvcd%2Ffv2dn%2Flarge%2FSIGRAFLEX-MF-Dichtung-WS-3870-IB14571.png)

El núcleo de esta junta consiste en una junta de grafito con un inserto de acero inoxidable. La junta está cubierta con una fina lámina de acero inoxidable (0,05 mm) por ambos lados. A continuación, se cubre con una fina capa de PTFE (0,05 mm). Los modelos de Juntas también tienen un borde interior. El sistema demuestra unas excelentes propiedades de sellado y también puede utilizarse como alternativa a los sistemas de sellado de PTFE.
