Function of this part

The aftertreatment system treats exhaust gases after they leave the engine using components such as the DOC, DPF, and SCR catalyst. It controls soot and NOx emissions by trapping particulates and converting harmful gases into less harmful compounds.

Why this part matters

These components are central to emissions compliance on modern diesel trucks. Problems in the aftertreatment system can cause frequent regens, power derates, and down-time until the fault is corrected.

About the brand

Cummins engine parts are trusted for reliable power in a variety of heavy-duty truck and equipment applications.

Fitment & usage

Used OEM parts are a smart choice for controlling repair costs while still using original-equipment components. Always match the OEM part number(s) listed to your existing part, and consult your service manual, dealer, or technician if you are unsure about fitment.

Note: Because this is a used component, normal signs of wear such as scratches, discoloration, or light surface corrosion may be present. Refer to the product photos and information on Second Truck Parts for the best representation of the part you will receive.

EPSON OEM ink....
Style: Ink
Good overpriced Epson ink. Tried aftermarket ink, worked FINE until Epson "update".....then got notice "invalid cartridge" and the printer would not operate. Bought OEM ink and it's happy again. I'm NOT.

EPSON 822 DURABrite Ultra Ink High Capacity Black Cartridge is a great product
Style: Ink
EPSON 822 DURABrite Ultra Ink High Capacity Black Cartridge is a great product. The 822 XL size will last you a long time. The color is perfect. it fits my printer perfectly. A great product and at a great price. I received it the same day that I ordered it. I did not know that I was running out of the black. The printer sends me messages that I am running out but I ignore the message and keep on printing hundreds of papers. Do not listen to your printer just keep printing until the cartridge is completely empty!!!

Stick To The Originals
Style: Ink
Tried remanufactured and off brand cartridges and kept running into compatability issues with my Epson Work Force Pro WF-3820. These are more expensive-but they work. Have to take into consideration the fact that my printer is used for business and down time because my new cartridges aren't recognized by the printer costs $$$
