Keep your truck’s emission system clean, protected, and working properly with this Fleetguard® UF106 Diesel Exhaust Fluid (DEF) Filter Kit. Designed for Cummins and non-Cummins engine applications, this DEF filter helps support reliable Selective Catalytic Reduction (SCR) system performance in medium-duty and heavy-duty trucks.

Suitable for commercial truck DEF systems and diesel exhaust fluid filtration applications requiring UF106 DEF filter compatibility.

Why Choose Fleetguard UF106 DEF Filter?

Clean DEF flow is important for proper emissions system operation. A clogged or contaminated DEF filter can affect SCR performance, trigger warning lights, reduce efficiency, and lead to costly downtime. This Fleetguard DEF filter is designed to help remove contaminants from the DEF system and support proper emission control performance.

This kit is ideal for routine DEF system maintenance and helps keep your truck operating within emission standards while protecting key aftertreatment components.

Please check the part number UF106, your engine application, and vehicle compatibility before ordering. Contact GP TRUCK if you need help confirming fitment.
