DESCRIPTION
The Diesel Exhaust Fluid (DEF) Header, also known as part number 5510443, is a component in the Selective Catalytic Reduction (SCR) system of a diesel truck. It is responsible for holding and distributing DEF fluid to the SCR catalyst, which reduces harmful emissions by converting nitrogen oxides into harmless nitrogen and water vapor. The DEF Header is typically made of durable materials such as stainless steel or aluminum to withstand the corrosive nature of DEF fluid. It features multiple ports for connection to various components within the SCR system, including sensors and pumps. Proper maintenance of the DEF Header is crucial for ensuring optimal performance and compliance with emissions regulations.
