730-4000 - Trident Marine Stainless Steel Constant Torque Clamp 5/8" Band, Hose I.D. - 4", Hose O.D. - 4.25" TO 5.125"

Stainless Steel Constant Torque Clamp 5/8" Band, Hose I.D. - 4", Hose O.D. - 4.25" TO 5.125"

Virtually all rubber hose compresses (cold flow) after installation of a 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 contract 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 without re-tightening or loosening the clamps. This clamping system is an “active” clamping mechanism, which monitors and then compensates for the changes by actually changing diameter through a unique worm gear Belleville assembly.
