Technical Structure

The connector consists of three components and thus enables quick and easy assembly. The clamping ring is firmly seated in the pressure nut - thus eliminating the loss of individual parts. Each connector is supplied as one part, not as a component kit, ready for the construction site. This eliminates the need to assemble individual parts on-site and ensures fast installation.

The term Poka Yoke originates from Japanese. It stands for continuous quality improvement by avoiding unintentional errors. To achieve this, technically intelligent designs are used.


The connector is made of high-quality material and complies with legal regulations. The reliable brass material ensures exceptional durability.


The metallic sealing makes the system fail-safe and maintenance-free. The connector possesses no seals that can become damaged or porous and thus impair function.

Our quick coupling system has been tested for compatibility with various corrugated conduit manufacturers. You can find the results in the download section to the right.
