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.

The Trident Marine Stainless Steel Constant Torque Clamp (part number 730-4000) is designed for securing hoses in marine and industrial applications where consistent clamping force is critical. This clamp features a 5/8" band and is suitable for hoses with an inner diameter of 4" and an outer diameter ranging from 4.25" to 5.125". It addresses the common issue of hose loosening due to temperature fluctuations or vibration by maintaining a constant torque, which helps prevent leaks and ensures system integrity. This product is intended for IT and facilities managers responsible for maintaining fluid transfer systems, particularly in environments where durability and reliable connections are paramount. Its stainless steel construction offers resistance to corrosion, making it a practical choice for demanding operational conditions. The constant torque mechanism reduces the need for frequent re-tightening, contributing to reduced maintenance overhead.
