xOverview
The Dorman 904-5201CD DEF filler cap is a purpose-built replacement designed to match the fit and function of the original cap on Freightliner Cascadia models from 2010 through 2020. Built for demanding on-road use, this cap supports proper sealing and reliable operation in daily fleet duty and long-haul routes alike.
Designed with attention to real-world conditions, the cap helps keep the DEF system protected from leaks and contaminants, reducing the need for frequent maintenance and helping you focus on the road ahead. Before you buy, use the garage tool to confirm fitment by entering your vehicle trim; if you see an information indicator, additional verification may be needed to ensure a precise match.
