Worm Drive Hose Clamps - Plain Band
Worm Drive Hose Clamps in accordance with DIN 3017 with spring inside
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 of ‘creeping’ (hose relaxation).
• Automatic re-tensioning effect in the event of hose relaxation
• Increased sealing reliability across a wide temperature range
