Trident Marine 730-8000 Stainless Steel Constant Torque Hose Clamp, 5/8-Inch Band

Stainless Steel Constant Torque Clamp 5/8 Band, Hose I.D. - 8, Hose O.D. - 8.25 to 9.125

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. - 8, Hose O.D. - 8.25 to 9.125
• 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 730-8000 Stainless Steel Constant Torque Hose Clamp is designed for demanding hose connection applications where reliable sealing and consistent clamping pressure are essential. This constant torque clamp features a 5/8-inch-wide stainless steel band and is suitable for hoses with an 8-inch inside diameter and outside diameters ranging from 8.25 to 9.125 inches. It is a practical choice for marine, automotive, industrial, and other systems that experience changing temperatures and hose compression.

Rubber hose commonly experiences cold flow after a clamp is installed, which can cause significant loss of installation torque. Conventional worm gear, T-bolt, and similar clamps are passive systems that cannot automatically compensate for hose compression or for the expansion and contraction of connected components. The Trident Marine 730-8000 uses an active clamping mechanism with a unique worm gear and Belleville spring assembly. This design helps monitor and compensate for changes in the connection by adjusting the clamp diameter, supporting more consistent sealing pressure without frequent manual retightening.

Specifications: The recommended maximum torque is 30 to 70 inch-pounds for smaller sizes up to 730-3000 and 50 to 120 inch-pounds for larger sizes above 730-3000. For this model, always follow the appropriate installation practices for the hose and application. Construction: The band and housing are made from 304 stainless steel, while the Belleville spring washers and screw use 401 stainless steel. This material combination provides durable corrosion resistance and dependable performance in challenging service environments.

Features:

• Constant Torque Design: Active clamping mechanism helps compensate for hose compression and thermal expansion or contraction.

• Application Fit: Designed for an 8-inch inside diameter hose with an outside diameter range of 8.25 to 9.125 inches.

• Stainless Steel Construction: 304 stainless steel band and housing provide durable corrosion resistance for demanding applications.

• Belleville Spring Assembly: 401 stainless steel spring washers support consistent clamping pressure over changing operating conditions.

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