  • Glossy anodized coating resists staining
  • Quality O-rings help seal the filler neck
  • Vented design
  • For DEF and fuel filler openings
  • Part number 55298

Detailed Description

Built for capless fuel and diesel exhaust fluid systems, Dorman 55298 provides a direct sealing solution for vehicles that use exposed filler necks. The aluminum construction and O-ring sealing surface help keep contaminants out of the fuel and emission system, while the anodized finish adds corrosion-resistant style. This part is a practical choice for Jeep Grand Cherokee and Ram owners looking for a cleaner, more controlled filler-neck closure. This part number 55298 also cross-references OE number 52029561AA for the same application.

What It Helps Address

  • Moisture entering a capless fuel or DEF filler neck
  • Dirt and road debris contamination at the fill opening
  • Staining or wear on exposed filler components
  • Loss of a secure seal at the fuel or DEF opening
  • Unfinished appearance around the filler area
