Stainless Steel Constant Torque Exhaust Clamp 3-1/2" Mfg# 730-3120

Constant Torque Clamps: All Stainless Steel 5/8" (16mm) wide band, liner, housing, screw and Bellville Springs. 7/8" (22mm) OD Range. Automatically expands and contracts to compensate for heat & cold.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. 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 assembly3 YEAR WARRANTY
