Doser Fluid Supply Module Cummins 4387304 | A052B661

Product Overview

The Cummins Doser Fluid Supply Module (Part Number 4387304) is a critical component of the vehicle’s exhaust aftertreatment system. It is specifically engineered to regulate and deliver Diesel Exhaust Fluid (DEF) to the dosing injector, facilitating the Selective Catalytic Reduction (SCR) process. By converting harmful nitrogen oxides (NOx) into harmless nitrogen and water vapor, this module ensures your commercial truck or industrial equipment remains compliant with stringent environmental regulations.

Key Features

• Precise DEF Delivery: Works in synchronization with the Engine Control Unit (ECU) to provide exact fluid dosing based on real-time engine load and exhaust temperature.
• Durable Construction: Built with high-grade materials designed to withstand harsh operating environments and chemical exposure.
• Seamless Integration: Engineered for a direct fit, ensuring easy installation and reliable communication with the vehicle’s diagnostic systems.
• Enhanced Efficiency: Optimizes the chemical reaction within the SCR catalyst, maintaining peak engine performance while reducing emissions.
