NORMA Constant Tension Clamps

NORMACLAMP® TORRO® CT Constant Tension Worm Drive Hose Clamps overcome "cold leaks" often experienced when installing new hoses. The radially positioned spring assures a continuous self-acting tightening effect. This is the only clamp to use for sealing hoses which are exposed to wide swings in temperature or have a tendency to "flow" under the pressure of the clamp. The TORRO® WF clamp is fitted with a wave spring which automatically re-tensions to ensure optimal radial clamping force. The TORRO® WF is the ideal choice for applications under extreme temperature changes (e.g. charged air), under extremely low temperatures or for the retention of hoses with a tendency of “creeping”/ hose relaxation. Advantages at a glance • Automatic re-tensioning effect in the event of hose relaxation • Increased sealing reliability across a wide temperature range Manufactured in Germany to DIN 3017 International standards they are used as standard OEM equipment on radiator and heater hoses by Ford Australia and GMH (General Motors Holden). Sizes Available From: 12mm to 140mm Band Widths: 9mm & 12mm Material Grade: W3 - Band, housing and screw completely stainless steel 1.4016 (430). Internal constant tension spring is stainless steel 1.4301 (304) Manufactured: Germany to DIN 3017 Standards
