Trident Marine 730-1120 Stainless Steel Constant Torque Hose Clamp Band ID - 5/8 1-1/4 to 2

The Trident Marine 730-1120 is a stainless steel constant torque hose clamp designed for demanding marine applications. Unlike standard worm-gear clamps, this constant torque design continuously compensates for hose compression (cold flow) that naturally occurs after installation, maintaining a reliable, leak-free seal over the life of the connection.

Rubber hoses inherently compress and deform after a clamp is tightened — a phenomenon known as cold flow. A standard clamp loses clamping force as this occurs, potentially leading to leaks. The constant torque clamp uses a coiled spring band that applies continuous radial pressure, automatically adjusting to keep sealing force consistent even as the hose material settles.

Key Features:

• Band Width: 5/8" — wide band distributes clamping force evenly and reduces hose damage
• Hose I.D. Range: 1-1/4" to 2" (31.75 mm to 50.8 mm)
• Hose O.D. Range: 1.75" to 2.625" (44.45 mm to 66.68 mm)
• Construction: Stainless steel for superior corrosion resistance in saltwater and freshwater marine environments
• Constant torque design automatically compensates for hose cold flow and thermal expansion/contraction
• Ideal for bilge, exhaust, fuel, water, and sanitation hose connections aboard vessels

The Trident Marine 730-1120 constant torque clamp is the professional-grade choice for any marine hose connection where long-term sealing integrity is critical. Its stainless steel construction ensures it stands up to the harsh moisture and salt exposure found in marine environments.
