Constant Tension Hose Clamp Manual Fitting Tools

Fitting a constant tension spring band clamp by hand is neither safe nor precise — the pre-loaded spring force that makes these clamps self-adjusting in service is exactly what makes them difficult to control during installation without the right tool. Our manual constant tension fitting tools are purpose-designed to compress the spring band fully and hold it open under load, freeing both hands to position the clamp accurately before controlled release onto the hose. The precision jaw geometry ensures even compression across the full clamp width — preventing the distortion that occurs when pliers or improvised tools are used — and protecting the spring temper from localised stress that could reduce the clamp's long-term tension output. Sized and profiled to work with the spring band formats used across the Tridon and Mikalor ranges, these tools are the standard fit-out for automotive workshops and fleet maintenance operations, HVAC engineers, and heavy-duty diesel technicians who work regularly with spring-loaded clamping systems and need consistent, damage-free results every time.
