Dorman 674-7005 Diesel Particulate Filter (DPF) Clamp

Dorman 674-7005 DPF Clamp Overview

The Dorman 674-7005 Diesel Particulate Filter clamp is a direct replacement for the original equipment clamp used in exhaust hardware applications. Built from stainless steel with a manual adjustment design, it is made to match the fit and function of the factory part for reliable DPF sealing and retention.

For diesel exhaust service on vehicles such as Ram 2500 and Ram 3500, this clamp supports a specific-fit installation where the original clamp has worn, corroded, or lost clamping force. The Dorman 674-7005 is engineered for consistent fitment and long-term service in demanding exhaust environments.

Detailed Description

This exhaust clamp is built to replace the original DPF clamp on the intended diesel application and restore proper connection at the filter joint. The stainless steel band and 1.6 mm material thickness help it withstand heat and corrosion exposure common in diesel exhaust systems. Dorman 674-7005 is a practical choice when servicing a DPF connection that needs a precise, OE-style clamp profile.

This part cross-references FEL-PRO 35806 for the same application. It is also associated with interchange numbers 21048521 and A4709950002. If you are sourcing a DPF clamp for Ram 2500 or Ram 3500 exhaust repair, verify the clamp diameter and connection style before installation.

Common Problems It Can Address

• Loose or weakened DPF clamp retention
• Exhaust leaks at the particulate filter connection
• Corrosion damage on the original clamp
• Improper sealing after exhaust service
• Fitment issues from a worn or distorted clamp

Installation Notes and Tips

Confirm the clamp diameter range matches the exhaust joint before installation. Clean the mating surfaces and inspect the DPF connection for damage, distortion, or carbon buildup that could affect sealing. Because this is a specific-fit clamp, use it only on the intended application and follow the vehicle service procedure for tightening and alignment.

Quality Assurance

Dorman manufactures this clamp as a direct replacement part and subjects it to industry-standard testing to support dependable performance. The stainless steel construction and OE-style fitment are intended to provide consistent service in diesel exhaust applications.
