Worm Drive Hose Clamps - Plain Band Improved asymmetric housing –– even distribution of forces and safe assembly Screw support – ase of assembly due to the safe guidance of the emerging band end e Material and clamping range stamped on the band – prevention of errors Asymmetric extension – revents the housing from tilting over when the clamp is tightened p Short housing saddle – even contact pressure S mooth 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. Within the NORMACLAMP® range, only the TORRO® has its trademark asymmetrical construction. The asymmetric housing provides high force, superior torque and even distribution of clamping pressure. Clamp aligns perfectly on the hose and ensures the optimal sealing of the connection. Multi-range hose clamp No chromium(VI) used for coating purposes Clamping ranges in acc. with DIN 3017: 8-12 mm to 140-160 mm Larger diameters available on request Types of clamp band and screw W2 x Corrosion resistance in salt spray testing *Max 10% base metal corrosion permissible * No chromium(VI) used for the coating on the closure components Material Joining cooling water lines Depressurized and pressurized fuel lines and ventilation systems Oil lines Joining lines in sanitary applications Joining lines in machine building applications Lines in the household appliance industry Hose lines in the commercial vehicle industries Phillips head Slotted head Band width 7.5 mm • W2, W3 with smooth inside Band width 9 mm • W1 with smooth inside • W2, W3, W4, W5 with stamped inside Band width 12 mm • W1, W2, W3 with smooth inside • W4, W5 with stamp

TORRO® WF (WAVE SPRING) The TORRO® WF clamp is fitted with a wave spring which automatically re-tensions to ensure optimal radial clamping force. The TORRO® WF is the ideal choice for applications under extreme temperature changes (e.g. charged air), under extremely low temperatures or for the retention of hoses with a tendency of “creeping”/ hose relaxation. Advantages at a glance • Automatic re-tensioning effect in the event of hose relaxation • Increased sealing reliability across a wide temperature range Materials W3, W4 NORMACLAMP® TORRO® WF Designation Clamping ranges in mm in inches

NORMACLAMP®® NORMACLAMP Worm Drive Hose Clamps - Plain Band The torque cap shears 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® TORRO® WITH TORQUE CAP Clamping ranges TORRO TORQUE CAP 60-80/9 TORRO TORQUE CAP 70-90/9
