TORRO® Worm Drive Hose Clamps - Plain Band Improved asymmetric housing - even distribution of forces and safe assembly Screw support - ease of assembly due to the safe guidance of the emerging band end Material and clamping range stamped on the band - prevention of errors Asymmetric extension - prevents the housing from tilting over when the clamp is tightened Short housing saddle - even contact pressure - improved efficiency Smooth or stamped inside of band - optimal hose protection Worm drive hose clamps in accordance with DIN 3017 NORMACLAMP® TORRO® multi-range hose clamps are ideally suited to applications with high mechanical loads. Thanks to the continuous developments these products have undergone, they remain the benchmark within modern clamp construction. The key feature of a NORMACLAMP® TORRO® product is its asymmetrical construction - an instant sign that it is a genuine TORRO®. Asymmetric housing provides high clamping force and superior torque strength. Even distribution of clamping pressure. Clamp aligns perfectly on the hose and ensures the optimal sealing of the connection.

TORRO® - Versions Worm Drive Hose Clamps - Plain Band NORMACLAMP® WF For this version of the NORMACLAMP® TORRO® the standard hose clamp is equipped with a spring insert on the inside of the clamp band. When tightening the screw the spring is loaded and stores sufficient clamping force to ensure a long-lasting automatic re-tensioning effect. Thus the radial clamping force achieved will be sufficient even under extremely low temperatures. Therefore, the TORRO® is an optimal solution for applications under extreme temperature changes (e.g., charged air) or for the retention of hoses with a tendency...

Torque cap Worm Drive Hose Clamps - Plain Band The torque cap shares off when the permissible tightening torque is reached, thus saving the need to use a torque wrench. The bolt slot can still be accessed even after the break-off point, meaning that the clamp can be removed and/or re-tensioned if necessary. Advantages at a glance • Defined tightening torque without the need for special tools • Installation can be checked visually Materials • W1, W2, W3, W4 NORMACLAMP® NORMACLAMP® TORRO® WITH TORQUE CAP

TORRO® - Versions Worm Drive Hose Clamps - Plain Band NORMACLAMP® Notch The notch is a clever means of prepositioning the TORRO® hose clip on the hose. In this case the oval hole in the clamp band finds its exact counterpart on the hose surface. Thus the TORRO® is safely and accurately kept in place prior to the final assembly. Advantages at a glance • Safe pre-assembly on rubber sleeves and molded pipes Materials • W3 NORMACLAMP® TORRO® NOTCH 9 TORRO NOTCH 16-27/9 TORRO NOTCH 20-32/9 TORRO NOTCH 23-35/9 TORRO NOTCH 25-40/9 TORRO NOTCH 30-45/9 TORRO NOTCH 32-50/9 TORRO NOTCH 35-55/9 TORRO...
