These connectors were developed to connect microducts with each other. Our system enables an easy, fast connection and disconnection of the microduct.

The connectors’ robust construction includes IP68 water ingress protection and resistance to high pressure fores, allowing them to be used in direct buried (DB) applications. The transparent body enables easy visual inspection of the cable within the connector. The straight push-in and endstop connectors have a fully plastic desgin utilising non-conductive parts only and are also free from metal parts.

The connectors are made in accordance with Standart CEI EN 50411-2-8. In addition, the uniformity of production is ensured by an external, recognised quality assurance program, TUV Süd.

Besides production uniformity, TUV Süd alsa tests the tightness, any pressure drop during tests, the tensile strenght of the microduct as well as the (cyclic) temperature change, waterproofness and ressitance to stress cracking solvents. Further, the connectors are subjected to visual inspection and a salt spray test.
