Keep clean diesel exhaust fluid flowing to your SCR system with the Wix Diesel Exhaust Fluid (DEF) Urea Filter WS10023, an in-tank DEF cartridge that strains contaminants out of the urea fluid before it reaches the pump and dosing components. It's a direct-fit replacement across a wide range of medium- and heavy-duty diesel applications, including the 2016-2023 Chevrolet Silverado 2500 HD, 2017-2023 GMC Sierra 3500 HD, 2010-2012 Ford F-650, 2009-2017 Freightliner Cascadia, and 2019-2026 Mack Anthem — see the Buyer's Guide tab for the full list of 157 applications.
In-tank DEF cartridge: mounts within the DEF tank to filter the urea fluid at the source.
Contaminant control: helps trap particulate so cleaner fluid feeds the SCR dosing system.
Maintenance-driven design: filtration is the foundation of an effective maintenance program, helping equipment stay closer to new condition longer.
WIX quality: part of a filtration line built around bases, connectors, installation aides and supplemental service items.
If a clogged or contaminated DEF filter is behind reduced fluid flow or SCR fault codes, this cartridge replaces it as part of scheduled service. Replace it at the interval specified in the vehicle service information.
