Dorman 674-7004 Diesel Particulate Filter (DPF) Clamp

Dorman 674-7004 DPF Clamp Overview

The Dorman 674-7004 Diesel Particulate Filter clamp is a direct replacement exhaust hardware part built to match the original clamp’s fit and function. It is made from stainless steel for corrosion resistance and long service life, with a bolt-style clamping design for secure retention in the exhaust system.

Compatible With select diesel exhaust applications, this DPF clamp is a specific-fit replacement for service work where the original clamp has worn, loosened, or failed. It is engineered for vehicles such as Ford F-250 and Ford F-350 diesel models where the exhaust aftertreatment system uses this clamp style.

Detailed Description

Dorman 674-7004 is designed as an OE-style Diesel Particulate Filter clamp that restores the original fit and function of the factory part. The stainless steel band and bolt-style clamp construction are selected for exhaust service, where heat and corrosion resistance matter. This part number is a practical choice for diesel exhaust repairs on Ford F-250 and Ford F-350 applications that use the specified clamp diameter range. Dorman 674-7004 also cross-references VB2011 for the same application.

Common Problems This Part Can Help Address

• Loose or leaking DPF clamp connections
• Exhaust soot escaping at the clamp joint
• Corrosion damage to the original clamp
• Improper sealing after exhaust service
• Clamp fatigue from repeated heat cycling

Installation Notes and Tips

Verify the clamp diameter range before installation and confirm the exhaust joint matches the specific-fit design. Clean the mating surfaces before tightening the bolt clamp to help achieve an even seal. Because this part is not reusable, inspect the connection carefully during service and replace any damaged exhaust components as needed. For Ford F-250 and Ford F-350 diesel repairs, confirm the clamp location and dimensions against the original hardware before final tightening.

Quality Assurance

This Dorman exhaust clamp is manufactured from quality materials and tested to industry standards for reliable performance. It is built to serve as a direct replacement for the original equipment clamp in the intended application.
