APPLICATIONS

The P68292411AA DEF Selective Catalyst is intended for compatible Cummins diesel engine exhaust aftertreatment systems. Always verify the original part number and vehicle configuration before purchase.

FUNCTION

The DEF Selective Catalyst is part of the exhaust aftertreatment system. In an SCR system, the catalyst facilitates a chemical reaction that helps convert nitrogen oxides (NOx) in diesel exhaust into nitrogen and water, reducing harmful emissions.

A worn, damaged, or failing DEF Selective Catalyst may cause symptoms such as:

• SCR system warning messages
• Emissions-related fault codes
• Increased NOx emissions
• Failed emissions testing
• Engine power derating
• Reduced aftertreatment system performance

WHY REPLACE A DEF SELECTIVE CATALYST?

A faulty DEF Selective Catalyst can affect the performance of the diesel exhaust aftertreatment system and its ability to reduce NOx emissions. Replacing a damaged or ineffective catalyst with the correct Genuine OEM Cummins component can help restore proper SCR system operation and support emissions compliance.
