Dorman 598-161 EGR Tube for Ford Super Duty

Dorman 598-161 is a direct replacement exhaust gas recirculation tube built for 1999 Ford F-250 Super Duty and 1999 Ford F-350 Super Duty applications. It is made from stainless steel and engineered to resist stress fractures, corrosion, and carbon buildup that can restrict exhaust gas flow.

Key Features

  • Direct replacement EGR tube for OE-style fit and function
  • Stainless steel construction for improved resistance to corrosion
  • Built to help reduce stress fracture concerns in high-heat service
  • Designed to limit carbon buildup blockage inside the tube
  • Includes the same features and components as the original EGR tube
  • Part number 598-161 for easy identification and ordering

Detailed Description

This exhaust gas recirculation line is made for emissions system service on 1999 Ford F-250 Super Duty and 1999 Ford F-350 Super Duty trucks. Dorman 598-161 matches the original equipment tube layout and uses a stainless steel body with a threaded end and two connectors for a direct replacement approach. The 18-inch tube measures 0.65 inches inside diameter and 0.75 inches outside diameter, helping restore proper EGR routing in the engine bay. This part cross-references Standard Ignition ETB9 for the same application.

Common Problems It Can Help Address

  • Cracked or stress-fractured EGR tubing
  • Corrosion-related exhaust leaks
  • Carbon buildup that restricts EGR flow
  • Failed emissions inspection caused by damaged EGR plumbing
  • Rough running conditions related to compromised exhaust gas recirculation routing

Installation Notes and Tips

Verify the tube routing, end style, and connector layout against the original part before installation. Inspect adjoining EGR components, mounting points, and sealing surfaces for wear or carbon deposits so the replacement tube can seat correctly. Because mounting hardware is not included, reuse or source the required hardware as needed for the vehicle.

Quality Assurance

Dorman designs this EGR tube as a direct replacement for the original equipment part, with construction focused on durability in heat- and corrosion-prone emissions service. Part number 598-161 is also listed under OE-style interchange references including EGT9 and F81Z9D477CA.
