Product Details

Trident Stainless Steel Constant Torque Hose Clamps are designed to expand and contract with the heat cycling found in engine exhaust hoses and systems. The Trident Constant Torque system is an "active" clamping mechanism, which compensates for system temperature changes by adjusting the hose clamp diameter through a Belleville worm gear assembly. 3 year warranty.

Info & Guides


Virtually all rubber hose compresses (cold flow) after installation of clamping device, resulting in an almost immediate torque loss that can exceed 80% of installation torque. Similarly, virtually all metal connections expand as a system heats up, and then contracts as the system cools. Conventional worm gear, T-bolt, and other clamps are passive, in that expansion or contraction of components cannot be compensated for with out re-tightening or loosening the clamps.

The Trident Constant Torque system is an "active" clamping mechanism, which monitors and then compensates for the temperature changes by actually changing diameter through a unique worm gear Belleville assembly.
