All Stainless Steel Constant Torque Clamp For 1-1/4 to 2 Inch Hose ID, 1.75 - 2.625 Inch Hose OD Range

An internal liner is included to protect soft hoses like silicone from damage caused by extrusion or shear.

Tightening torque runs between 90 and 125 inch pounds, and a torque wrench is the recommended way to get there reliably. Once it's properly set, the screw tip should stick out past the housing by around a quarter inch, and the Belleville washer stacks should be nearly flat. That visual check is built right into the clamp design so you're not just guessing at whether it's snug enough.
