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.
