Gaskets - DPF & DOC

At American Radiator, we carry a full selection of replacement gaskets for DPF and DOC systems designed for heavy-duty trucks and equipment. Each DPF gasket is manufactured to OEM specifications, ensuring the proper fit, durability, and performance your emissions system demands. Unlike reused seals, which can compromise performance, new aftermarket gaskets help maintain airflow efficiency and extend the service life of your DPF or DOC filter.

Our diesel exhaust gaskets are available with no minimum order requirements, and many part numbers can be purchased individually wrapped for convenience. Whether you manage a large fleet or operate a single truck, replacing gaskets during scheduled DPF cleaning is essential to avoid leaks, loss of pressure, or premature failure.

American Radiator offers aftermarket gaskets for leading brands including Cummins, Volvo, Detroit Diesel, International Navistar, Paccar, and Mack, giving you broad coverage for most diesel applications. Backed by competitive pricing and our famous same-day shipping, you can get the parts you need quickly to minimize downtime.
