NORMACLAMP TORRO worm drive hose clips

NORMA TORRO Hose Clamps set the standards of modern hose clamp design. With its tensile strength, high fracture torque and even band tension force distribution, the NORMACLAMP TORRO opens up a new dimension for worm drive clamps.

The combination of these features of the NORMACLAMP TORRO hose clamp assist in achieving exceptional clamping load around the spigot, at recommended installation torque levels. This provides the best possible seal, while providing maximum hose protection against damage at the minimum of effort.

All NORMACLAMP TORRO clamps are manufactured to the standard DIN 3017.
This defines the tension ranges to be met by each clamp size.

NORMACLAMP TORRO material grades and description:

• W1 - All components completely zinc plated steel clear chromate.
• W2 - Bands and housings made of chromium stainless steel 1.4016 (430).
  Closure components made of steel, zinc plated.
• W3 - All components completely stainless steel 1.4016 (430).
• W4 - All components completely marine grade stainless steel 1.4301 (304).

NORMACLAMP TORRO automotive applications:

With its tensile strength, high fracture torque and even tension force distribution, the NORMACLAMP TORRO opens up a new dimension for worm drive hose clips.

• Oil lines.
• Cooling water lines.
• Depressurized as well as pressurized fuel lines and vent lines.
• Air ducts, both vacuum and excess pressure applications. (e.g. charged air)
