With a thickness of 1.2mm, this gasket balances flexibility and strength, making it suitable for heavy-duty applications in diesel trucks and commercial vehicles.

Compatible Vehicles and Applications

This diesel particulate filter gasket is compatible with a range of diesel-powered vehicles requiring a 257mm inside diameter DPF gasket. It is commonly used in diesel trucks and commercial vehicles from manufacturers such as Ford, Chevrolet, and Dodge that specify this size for their exhaust systems. The Dorman 674-9052 gasket is ideal for addressing issues related to exhaust leaks and emission system failures.

• Seals exhaust leaks at the diesel particulate filter connection
