Product Description
Cummins DEF Doser Injector Male Connector 2880305 is a replacement fitting designed for the diesel exhaust fluid (DEF) dosing system on compatible Cummins diesel engines.
This connector provides a connection point for the DEF fluid line at the dosing injector assembly. It is designed to help maintain a secure connection and proper fluid delivery within the selective catalytic reduction (SCR) aftertreatment system.
Used in select Cummins diesel engine configurations, including certain EPA13 6.7-liter ISF and QSF engines.
The connector is associated with Cummins O-ring 2880306, which provides sealing at the fitting connection.
Suitable for replacement during DEF injector servicing, aftertreatment system maintenance, or repairs involving damaged or leaking fittings.
Important Fitment Note: Cummins identifies 2880305 as a male connector associated with the DEF doser injector assembly, rather than the complete DEF pump. Parts diagrams list O-ring 2880306 separately.
Sold individually. Verify compatibility with your engine serial number and DEF dosing system before ordering.
