C3609967 is a genuine Cummins metal single-bolt tube/hose clamp, designed for securing and sealing rubber hoses to hard fittings on fuel, oil, water, and air lines. It prevents loosening, leaks, and disconnection under engine vibration. Made of cold-rolled steel with zinc plating, it features a semi-circular design with single-bolt locking. Fits Cummins 6BT, 6CT, ISBe, QSB engines, widely used in construction machinery and commercial vehicles.
