NORMACLAMP® TORRO®
Worm drive hose clips to DIN 3017
The NORMACLAMP® TORRO® multi-range hose clips are - depending on the bandwidth - ideal for use in many different applications with a high mechanical load. With its tensile strength, the high fracture torque and the even tension force distribution plus the constantly improved design it still sets standards for modern hose clips. A TORRO® clip can be recognised immediately and unmistakeably by its typical technical feature: The patented asymmetric construction.

Tensile strength with higher fracture torque
The new NORMACLAMP® TORRO® still features high tensile strengths, however, when compared with competitive products and the previous model, the fracture torque values are significantly higher. This provides for a high level of safety.
Even tension force distribution
With a change in technical design the even distribution of tension forces was still improved. The clamp fits perfectly on the hose and ensures an optimal tightness of the system.
