NORMAClamp® TORRO® Worm Drive Hose Clamps

German-engineered quality and reliability.

NORMAClamp® TORRO® multi-range hose clamps are ideally suited to applications with high mechanical loads. Made in Germany, the continuous development these clamps undergo ensures they remain the benchmark within modern clamp construction.

The key feature of TORRO® worm drive hose clamp is its asymmetrical construction - an instant sign that it is a genuine TORRO®. The asymmetric housing prevents the clamp from tilting on the pipe and ensures an optimal seal.

TORRO® clamps have been engineered to reach exceptionally high band tension values - A higher band tension at nominal tightening torque results in higher efficiency of the hose clamp.

Available in clamping ranges 8-16 mm to 140-160 mm with DIN 3017 (larger diameters available on request) these versatile clamps are a must-have in any toolbox.

For superior quality, reliability and user-friendly features, you can’t go past TORRO®

  • (1) Improved asymmetric housing – even distribution of forces, safe assembly
  • (2) Screw support – screw collar prevents band tail from lifting when clamp is tightened, enabling easy, safe assembly
  • (3) Specification stamp on inside of band – quick reference to material grade & clamping range for prevention of errors
  • (4) Asymmetric extension – prevents housing from tilting over when clamp is tightened
  • (5) Short housing saddle – even contact pressure, Improved efficiency
