Trident Marine 730-1120 Stainless Steel Constant Torque Clamp, 5/8-Inch Band

Stainless Steel Constant Torque Clamp 5/8 Band, Hose I.D. - 1-1/4 to 2, Hose O.D. - 1.75 to 2.625

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 assembly.

Specifications:

• Hose I.D. - 1-1/4 to 2 Hose O.D. - 1.75 to 2.625
• Recommend max. torque - smaller id. sizes up to 730-3000 - 30 to 70 in.-lbs, larger id. sizes above 730-3000 - 50 to 120 in.-lbs

Construction:

• Band Housing: 304 Stainless Steel 5/8 Wide Band
• Bellville Spring Washers Screw: 401 Stainless Steel

Trident Marine Part Number 730-1120 Stainless Steel Constant Torque Clamp is designed to provide reliable, consistent sealing for rubber hose connections in marine, automotive, industrial, and other demanding applications. The clamp features a 5/8-inch-wide stainless steel band and accommodates hose inside diameters from 1-1/4 to 2 inches, with compatible hose outside diameters from 1.75 to 2.625 inches.

Rubber hose naturally compresses, or cold flows, after a clamping device is installed. This can cause significant torque loss shortly after installation, while metal connections may expand as a system heats and contract as it cools. Conventional worm gear and T-bolt clamps are passive and typically require manual adjustment to compensate for these changes. The Trident Marine constant torque design actively responds to changing conditions by adjusting its diameter through a unique worm gear and Belleville spring assembly.

This active clamping mechanism helps maintain more consistent sealing pressure as hose and connection materials change with temperature and use. It is well suited for applications where dependable hose retention and reduced maintenance are important. For smaller inside-diameter sizes up to 730-3000, the recommended maximum torque range is 30 to 70 inch-pounds. For larger inside-diameter sizes above 730-3000, the recommended maximum torque range is 50 to 120 inch-pounds. Always select the torque setting appropriate for the application and hose assembly.

Construction: The band and housing are manufactured from 304 stainless steel for corrosion resistance and durability. The Belleville spring washers and screw are made from 401 stainless steel. With its constant torque operation, robust materials, and broad hose compatibility, the Trident Marine 730-1120 clamp provides a dependable solution for maintaining secure hose connections in demanding environments.

Features:

• Constant torque design: Actively compensates for hose compression and thermal expansion or contraction to help maintain consistent sealing pressure.

• Hose compatibility: Fits hose inside diameters from 1-1/4 to 2 inches and hose outside diameters from 1.75 to 2.625 inches.

• Band and housing: Constructed from corrosion-resistant 304 stainless steel with a 5/8-inch-wide band.

• Spring washers and screw: Manufactured from durable 401 stainless steel.

• Recommended torque: Use 30 to 70 inch-pounds for smaller inside-diameter sizes up to 730-3000 and 50 to 120 inch-pounds for larger sizes above 730-3000.

• Applications: Suitable for marine, automotive, industrial, and other hose connection applications requiring dependable clamping performance.
