This filter is widely used across multiple OEMs (Freightliner, Mercedes-Benz, Detroit Diesel, Paccar, Navistar) that employ the same filter design.

It removes contaminants and crystallized urea from the DEF fluid before it enters the injector and SCR catalyst, protecting sensitive components from clogging and wear. Fleetguard (a Cummins brand) recommends replacing the DEF filter every 200,000 miles to maintain proper emissions performance, prevent injector failure, and avoid costly SCR system repairs.
