Description

When you’re pushing through a long planting season or harvest, the last thing you want is a DEF system fault shutting down your tractor in the middle of a critical field. This DEF tank filter keeps your diesel exhaust fluid clean and free-flowing so your emissions system works like it should, preventing those dreaded warning lights and power derates that can cost you precious time when every hour counts.

What You’re Getting

Fine mesh filtration that catches contaminants before they can clog your DEF injectors
Direct OEM replacement that fits exactly like the original factory filter
Corrosion-resistant materials designed to handle DEF’s chemical properties
Proper flow characteristics that keep your SCR system supplied with clean fluid

Built for Real Farm Work

This filter fits an extensive range of John Deere equipment from compact 5E series utility tractors up to the massive 9RX tracked machines. Whether you’re running a 6M series tractor for dairy operations, pulling heavy implements with an 8R series row-crop machine, or operating a combine during harvest, this filter keeps your DEF system running clean on everything from telehandlers to cotton pickers.

Made to Last

DEF can be tough on components over time, but this filter’s built to handle it. The materials resist the corrosive nature of diesel exhaust fluid while maintaining proper filtration through temperature swings and the vibration that comes with field work. It’s the same quality filter that came on your machine from the factory.

Good to Know

DEF tank filters typically need replacement during scheduled maintenance intervals or if you notice DEF system faults. Always use fresh, quality DEF fluid when servicing the system, and check that the tank cap seals properly to prevent contamination. If your DEF has been sitting for extended periods, this is a good time to drain and refill with fresh fluid along with the new filter.
