Finding the right diesel emissions part online may seem impossible. Worse, you think you’ve found the right part only to realize it doesn’t fit!!! Or you find an online store but they don’t carry your model. Then there’s OEM parts, aftermarket parts…. and all these numbers… geesh! Even for seasoned Fleet Managers, finding the best deals and right parts can be a challenge… not to mention owner operators who may not know the industry lingo or even what search terms to use.

To ensure you’ve got the right part, you’ll need to locate the TAG on your DPF and find the OEM Part Number, which is an industry reference number.

OEM Numbers vary by manufacturer; for example Cummins OEM #s are identified as the C P/N number, while Detroit models start with a letter. It is also very common in this industry for there to be many different OEM #s for the same product, because of various manufacturer changes over the years. These are considered OEM cross reference numbers (OEM crosses for short). Here are some examples of DPF & DOC tags:

Again, not every device is the same. Some have 5 or 6 numbers on them, which can be very confusing. But locating your tag or the stamped area shouldn’t be too difficult. You can always call in and our parts manager can look up your replacement by VIN#, if the tag is damaged or imprint illegible.
