Diesel Exhaust Fluid Header Cummins 5296451 | A041G027

Product Overview

The 5296451 Diesel Exhaust Fluid (DEF) Header is a critical component of the Selective Catalytic Reduction (SCR) system in heavy-duty Cummins engines. It serves as the primary interface within the DEF tank, facilitating the precise delivery of fluid to the aftertreatment system to ensure effective reduction of nitrogen oxide (NOx) emissions.

Key Features and Benefits

• Precision Delivery: Engineered to ensure the even distribution of DEF into the exhaust stream, optimizing the chemical reaction that converts harmful pollutants into harmless nitrogen and water vapor.
• Durable Construction: Manufactured from high-grade, corrosion-resistant materials designed to withstand the chemical properties of DEF and the high-temperature environment of heavy-duty trucking.
• System Efficiency: Maintains correct fluid pressure and levels, acting as a pivotal link between DEF storage and the SCR catalyst.
• Environmental Compliance: Helps operators meet stringent environmental regulations and avoid penalties by maintaining the integrity of the emission control system.
