Product Overview – Constant Torque Clamp 1.31 in to 2.25 in
Part No. OTX-4CT0028 is a constant torque clamp that fits hoses from 1-5/16 in to 2-1/4 in (33–57 mm), ideal for coolant and heater hoses in heavy-duty service.
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.
