FAMA Heeled Tooth Technology

FAMA has patented a special and innovative design for its connectors. The heeled tooth came about after a thorough examination of existing products, identifying weak points and proposing improvements. The FAMA connector has a gripping system that fits immediately without creating gaps.

The female’s tooth shape, the male’s tooth shape, and the materials used protect the system against any misaligned insertions that often occur during the segment launching phase. Therefore, it can be safely said that this connection system offers greater strength. The FAMA connector, in synergy with the third-generation gasket, provides excellent sealing results, significantly reducing water ingress.

FAMA connectors have outstanding shear and pull-out performance and are manufactured to meet specific customer technical requirements.

The range of FAMA connectors is integrated with special connectors used for specific requirements, with which Cross Passage, launch rings, test rings and more stand out.
