High band tensile force and high 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.


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.
