Item description

The NORMACLAMP® TORRO® worm drive hose clamp according to DIN 3017 is a multi-range hose clamp, particularly suitable for applications with high mechanical stress. Thanks to continuous development, it remains the benchmark for modern clamp design. The most characteristic feature of the NORMACLAMP® TORRO® is its asymmetrical housing – this is how you can immediately recognize a genuine TORRO®.

The robust construction and high-quality workmanship made of corrosion-resistant materials (W1 to W5) make the TORRO® the ideal choice for various industrial and automotive applications. All closure components are completely chrome-VI-free coated. Assembly is easy with standard tools.

Product advantages
  • Improved asymmetrical housing design – even force distribution and secure mounting
  • Screw support bearing – easy assembly due to secure band guidance
  • Material and clamping range embossing – prevents mix-ups
  • Asymmetrical extension – prevents the clamp head from tipping when tightened
  • Short housing saddle – even contact pressure for better sealing performance
  • Inner band smooth or embossed – optimal hose protection
  • Chrome-VI-free coating of all closure components
  • High band tensile forces and significantly increased breaking torques compared to the previous model
Areas of application
  • Cooling water connections
  • Pressureless and pressurized fuel lines and vents
  • Oil lines
  • Connections of lines in the sanitary sector
  • Connections of lines in mechanical engineering
  • Lines in the household appliance industry
  • Hose connections in the commercial vehicle industry
