<p><strong>Stainless Steel Constant Torque Clamp 5/8&quot; Band, Hose I.D. - 4&quot;, Hose O.D. - 4.25&quot; TO 5.125&quot;</strong></p><p id="isPasted">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 &ldquo;active&rdquo; clamping mechanism, which monitors and then compensates for the changes by actually changing diameter through a unique worm gear Belleville assembly.</p><p><strong>Specifications:</strong>&nbsp;</p><ul><li>Recommended max. torque - smaller ID.
