Norma Bandwidth 9mm Hose Clamp 50-70mm
Worm Drive Hose Clamps 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.

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.
