All Stainless Steel Constant Torque Clamp For 1 to 1-1/2 Inch Hose ID, 1.25 - 2.125 Inch Hose OD Range

This constant torque clamp is designed to compensate for expansion and contraction caused by temperature extremes. It uses Belleville spring washers to maintain consistent pressure, so it should hold tight even with engine heat.

Built with an internal liner, it keeps the band from biting into soft or silicone hose material, which is exactly where standard worm gear clamps tend to cause damage over time. You get a secure hold without the extrusion or shear damage that shows up on softer hose walls.
