BRP 276000455 Lower Formed Hose Assembly

This lower formed hose is a genuine BRP (Bombardier Recreational Products) original equipment manufacturer component designed for Sea-Doo personal watercraft. It functions as a critical conduit within the engine cooling and exhaust cooling circuits, ensuring precise flow of raw water or coolant. Constructed from high-temperature reinforced EPDM rubber compound, the hose features pre-formed geometry to match the tight routing constraints of the hull and engine compartment. It connects the water intake pump or thermostat housing to the engine block, intercooler, or exhaust manifold depending on specific model application. The part supersedes earlier revisions 276000137 and 276000245, incorporating updated material formulation for improved resistance to saltwater corrosion, ozone degradation, and thermal cycling fatigue. Installation requires OEM-spec clamps and torque specifications to prevent leakage under vibration and pressure pulsation.
