Detailed Description

This diesel particulate filter gasket is built to restore the sealing surface between the DPF and adjoining exhaust components. The stainless steel material helps it withstand exhaust heat and service conditions, while the factory-style dimensions support a proper fit where the original seal has failed.

This part cross-references OE-style numbers such as 8976282570 and G01202 for the same application.

Common Repair Symptoms

• Exhaust leak at the DPF joint
• Soot buildup around the filter connection
• Damaged or flattened original gasket
• Noise from a leaking diesel exhaust seal
• Service issues after DPF removal or replacement

Installation Notes and Tips

Inspect the mating surfaces before installation and remove carbon, soot, and corrosion so the new gasket can seat evenly. Confirm the DPF flange and adjoining exhaust components are not warped or cracked, since surface damage can prevent a proper seal. Use the gasket only on the specified diesel particulate filter connection and verify dimensions against the removed part before assembly.

Quality Assurance

Dorman manufactures this gasket as a direct replacement part built to match the function of the factory seal. The stainless steel construction and OE-style dimensions support consistent exhaust sealing in diesel service.
