Constant torque hose clamps (also called constant tension clamps) use heavy-duty belleville spring washers to apply continuous self-adjusting clamping pressure as the hose expands and contracts with temperature changes. Unlike standard worm drive clamps, which require re-tightening after thermal cycling, constant torque clamps maintain consistent load automatically making these the correct choice for high-temperature coolant systems, turbo and intercooler connections, and any application where thermal movement would cause a fixed clamp to work loose.

These heavy duty clamps are available in a large range of popular sizes to suit turbo and air intake hoses providing a higher clamping force suitable for large diesel engines in trucks and marine crafts.

Suitable for high-performance automotive, commercial vehicle, agricultural, and industrial installations where thermal cycling is severe and re-tightening is impractical.

Correct installation torque is confirmed when the screw tip at the back of the housing is fully extended when tightened see image on this page.
