Torro® Worm Gear Clamps with Integrated Springs add an automatic self-adjusting constant tension to the 9 or 12mm asymmetric worm drive clamp. Tightening the screw loads the spring with enough clamping force to ensure a long-lasting automatic re-tensioning effect, even in very low temperatures. The self-adjusting radial clamping force achieved makes these ideal for applications under extreme temperature changes (e. g. charged air) or for the retention of hoses with a tendency of "creeping" (hose relaxation). They are particularly suited to connecting cooling and heating hoses.

Features and Benefits N/A
  • Automatic self-adjustment when hose relaxes
  • Increased sealing reliability over wide temperature ranges
  • Euro-style inner band is stamped, not slotted, to protect the hose from even extreme compression
  • Patented asymmetrical housing prevents screw head from tilting out when tightened
  • Short housing saddle provides even pressure around the hose without welding or rivets
  • Large Diameter Range - hoses of varying diameters can be secured with a single clamp size
  • Combination Screw - hex, slotted and Phillips to meet practical needs
  • Emerging band end is deflected away from the screw head, forming a firm closure without pushing off the socket spanner
