Description

If you’ve been running a newer John Deere with Tier 4 Final emissions, you know that keeping the DEF system happy is critical to avoiding those frustrating derate situations that can shut down your operation. This inline DEF filter sits between your tank and the injection system, catching any contamination that could plug nozzles or damage the delicate SCR components that keep your emissions compliant and your engine running at full power.

What You’re Getting

High-efficiency filtration designed specifically for urea-based DEF fluid chemistry
Corrosion-resistant construction that won’t break down from harsh DEF conditions
Precision filtering that removes crystalline deposits and foreign particles before they reach injection nozzles
Temperature-stable design that works reliably in all weather conditions
Direct replacement fit with no modifications needed

Built for Modern Farm Work

This filter protects the aftertreatment systems on John Deere’s most advanced tractors and construction equipment. Whether you’re pulling heavy tillage implements with a 9R series four-wheel-drive, running precision planting operations with a 7R series, or handling loader work with a 6R utility tractor, clean DEF fluid is essential for maintaining full power and meeting emissions standards.

Made to Last

The SCR emission systems on these tractors are sophisticated and expensive to repair. This filter uses specialized media that’s compatible with DEF’s corrosive properties and won’t deteriorate like standard filters would. The housing construction prevents leaks and maintains proper flow rates even under the pressure and vibration of heavy field work.

Good to Know

Replace this filter according to your service manual intervals or if you notice any DEF system warning codes. When changing, make sure to properly depressurize the system first—DEF fluid can be under pressure and will spray if released quickly. Always use fresh, quality DEF fluid and avoid contaminating the system during installation.
