Product Overview – Constant Torque Clamp 0.81 in to 1.50 in
The Constant Torque Clamp 0.81 in to 1.50 in (Part No. OTX-4CT0016) is a constant torque clamp with a clamping range of 13/16 in to 1-1/2 in (21–38 mm), made for coolant and heater hoses on trucks, buses and off-highway equipment.
Unlike a standard worm clamp, a constant torque clamp compensates for hose shrinkage over hot and cold cycles, so it does not need constant re-tightening.
Construction: a 301 stainless steel band 9/16 in wide, a 410 stainless steel screw with a 5/16 in hex, with a torque rating of 70 in-lbs.
It interchanges with 7 aftermarket part numbers from brands such as Automann, Breeze, Excoh, Norma, including Automann 561.2416, Excoh 4CT0016, Norma 3620302029.
Tip: always match the clamp size to the outside diameter of the joint, not the pipe or hose inside diameter.
