Technical Details and Product Specifications

The Dorman 674-9004 gasket is crafted from MBG-D material, known for its ability to withstand the high temperatures and corrosive environment typical of diesel exhaust systems. Its silver color coating adds an extra layer of protection against rust and wear. The one-piece configuration simplifies installation and reduces the risk of leaks. With an inside diameter of 240 mm and an outside diameter of 260 mm, this gasket is designed to fit diesel particulate filter housings requiring these precise dimensions. The 3.2 mm thickness provides the necessary compression to maintain a secure seal without deformation under thermal cycling.

Compatible Vehicles and Common Applications

• Compatible with diesel trucks and SUVs requiring a 240 mm inside diameter DPF gasket
• Suitable for diesel exhaust systems needing a 3.2 mm thick sealing gasket
• Used in maintenance or replacement of diesel particulate filter seals to prevent exhaust leaks
• Addresses issues such as exhaust leaks, DPF housing damage, and poor emissions control
• Helps maintain proper exhaust backpressure and system efficiency

Installation Notes and Tips

Ensure the mating surfaces of the diesel particulate filter and exhaust components are clean and free of debris before installing the gasket. Proper alignment of the gasket is critical to avoid exhaust leaks. Use appropriate torque specifications for bolts to prevent gasket damage or compression beyond recommended limits. Replacement of both gaskets included in the package is recommended when servicing the DPF to maintain system integrity.
