Cummins 201989 V Band Clamp Assembly

The Cummins 201989 is a V-band clamp designed to secure turbocharger exhaust outlet connections on heavy-duty diesel engines. It is manufactured from high-grade stainless steel to withstand extreme thermal cycling, vibration, and corrosion in commercial vehicle and industrial power generation applications. This clamp serves as a direct replacement for Cummins OEM part numbers 3803433, 3522631, 3029631, 3089765, and 3633805. It is engineered to maintain exhaust system integrity under high backpressure and temperature conditions typical of K19, K38, K50, QSK19, QSK38, QSK60, and QST30 engine platforms. Installation requires standard hand tools to achieve specified torque for leak-free sealing.
