Basic Concepts of Aftertreatment Device Inlet Gaskets

An Aftertreatment Device Inlet Gasket is a sealing component positioned between the engine exhaust system and the aftertreatment device, such as a Diesel Particulate Filter (DPF) or Selective Catalytic Reduction (SCR) system. Its primary function is to create a tight seal, preventing exhaust gases from escaping and ensuring they pass through the aftertreatment device for proper filtration and treatment. These gaskets are typically manufactured from materials like graphite, metal, or composite materials, chosen for their ability to withstand high temperatures, chemical exposure, and mechanical stress ¹.
