Both 13.00″ and 10.50″ Pancake Diesel Oxidation Catalysts are in stock for a Wide Range of Cummins Applications.
At DPFXFIT, our product offering is fully stacked. We are proud to announce the industry’s largest pancake DOC selection in the aftermarket, covering both the 13.00″ and 10.50″ form factors across a wide range of Cummins engine applications.
Whether you are servicing a Cummins ISB 6.7, a B6.7, an L9, an ISL9, an X12, or an X15, DPFXFIT has a direct-fit pancake diesel oxidation catalyst built to deliver OEM performance and durability with aftermarket affordability.
Why the Pancake DOC Matters for Your Shop or Fleet
The pancake DOC format is a compact, low-profile diesel oxidation catalyst design found on a broad range of Cummins engine platforms in medium and heavy duty applications. Unlike conventional cylindrical DOC configurations, the pancake form factor presents a shorter overall profile that must fit precisely within tighter aftertreatment packaging. Getting the right diameter, the right substrate loading, and the right canister construction is not something you can leave to chance.
That is exactly why DPFXFIT has taken the time to develop a comprehensive pancake DOC lineup built to the same exacting standards as every other product in our catalog. Every unit is designed and manufactured in North America by GESi (Global Emissions Systems Inc.), with over 20 years of aftertreatment manufacturing experience behind every part.
No Cores. No Guesswork. No Shortcuts.
Every DPFXFIT pancake DOC is a new unit, never remanufactured or reconditioned. You get a fresh catalyst substrate with a full washcoat loading, housed in a durable stainless steel canister, with OEM-quality clamps and gaskets included. There is no core charge and no core to return.
Each unit carries DPFXFIT’s 3-year unlimited mileage warranty, giving your customers the confidence to keep rolling without worrying about premature DOC failure.
