Product Overview – Constant Torque Clamp 0.81 in to 1.75 in
When a standard clamp is not enough, the OTX-4CT0020 constant torque clamp (13/16 in to 1-3/4 in (21–44 mm)) gives a dependable seal on coolant and heater hoses.
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 561.2420, Excoh 4CT0020, Norma 3620302033.
Tip: replace clamps whenever a joint is opened for service; a used clamp may not seal to the same load.
