How to Identify the Correct DPF Gasket Without a Part Number

Identifying the correct DPF gasket, clamp or kit is important, not only for the fitment, but also to ensure that your truck is meeting the required Euro emissions standard. If you don’t have the OEM number for the parts that you need, there are still ways to find the correct gaskets for your DPF.

Where possible, we try to include all compatible vehicles in the description of each part, however we can assist you with finding the right part for your truck and engine. The more information you can have at the ready, the easier it will be to find the correct part number for you.

Vehicle Brand, Model and Emissions Standard

The brand, model and emissions standard are always the most important details when identifying the right DPF gasket for your vehicle.

Always make a note of:

  • Manufacturer (Scania, Volvo, MAN, DAF, Mercedes, etc.)
  • Model (P/G/R, VNL, TGX, CF, Antos, etc.)
  • Emissions standard (Euro 6, EPA 2010, etc.)

Euro 6 systems use particularly more complex DPF and SCR layouts than earlier emissions standards, resulting in a larger variety of gasket designs.

If possible, it is also helpful to note:

  • Engine size or code.
  • Year of manufacture.

This information can narrow the potential list of gaskets down to a small number of options.

Measure the Existing Gasket (or Flange)

If the original gasket is still available, measurements can be another helpful tool to finding the right OEM number.

Key measurements include:

  • Inner Diameter (ID)
  • Outer Diameter (OD)
  • Thickness
  • Shape (flat, stepped, tapered, or conical)

Even a work gasket can help to provide accurate dimensions. In the absence of the original gasket, measuring the mating flanges on the exhaust or DPF housing can also confirm the size.

Check the Gasket Type and Material

Understanding the material and shape of the DPF gasket can also be a big indicator. Brands often stick to similar materials, shapes and sizes, for example Volvo often use flat metal gaskets, whereas Scania prefer to use graphite.

Common materials include:

  • Graphite (braided, flat or compressed)
  • Stainless steel or carbon steel (braided, knitted or flat)
  • Mica (flat or compressed)
  • Glass fibre (rope)
  • Silica (rope)
  • A mixture of the above.

Common shapes include:

  • Flat
  • Rope
  • Conical
  • Tapered
  • Trapezoid
  • Square
