NORMACLAMP® TORRO®

Worm drive hose clips to DIN 3017

The NORMACLAMP® TORRO® multi-range hose clips are - depending on the bandwidth - ideal for use in many different applications with a high mechanical load.  With its tensile strength, the high fracture torque and the even tension force distribution plus the constantly improved design it still sets standards for modern hose clips. A TORRO® clip can be recognised immediately and unmistakeably by its typical technical feature: The patented asymmetric construction.

NORMACLAMP®TORRO®  Modular System

The TORRO® modular system offers several accessories that can be added to the clip. Thus its technical features can be modified. You are free to combine two or more of these accessories according to your requirements.

 

Please ask us.

The torque cap

The torque cap cuts off when the permissible torque is reached and thus saves the need for a torque wrench.

Even without the cap the hose clip still remains adjustable and can be disassembled and/or retightened if necessary.

 

 

Advantages:

  • Defined tightening torque without special tool
  • Visual assembly control

The pre-assembly clip

With this accessory theTORRO® can be pre-positioned on the hose. The two "teeth" of this device keep the TORRO® hose clip safely in place if it needs to be stocked or transported prior to its assembly.

 

Advantage:

  • Safe pre-positioning on the hose

The Notch

The notch is another clever way of pre-positioning the TORRO® hose clip on the hose. In this case the notch finds its exact counter part on the hose surface. Thus the TORRO® is safely and accurately kept in place prior to the final assembly.

 

Advantage:

  • Safe pre-positioning on the hose

The spring insert*

For this version of the NORMACLAMP® TORRO® the standard hose clip is equipped with a spring insert on the inside of the clip 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).

 
Advantages:

  • Automatic re-tensioning effect in the event of hose relaxation
  • Increased sealing reliability across a wide temperature range

The safety collar

The safety collar is an assembly aid consisting of a plastic collar that is easily fixed on the screw head. It prevents the screwdriver from slipping off the screw head thus the assembly is much easier. The safety collar matches our standard screw head size 7.

 

Advantage:

  • The screwdriver is kept from slipping off the screw head during assembly

The thumbscrew

Advantage:

  • The TORRO® hose clip can be manually tightened and opened

IMPORTANT NOTE:


Please make sure that the NORMACLAMP® TORRO® accessory you wish to order is suitable for your application as well as for:

 

  • The clip diameter
  • The screw head size
  • The material combination.
