The terms, conditions, and details of our warranty vary from product to product. Specific warranty details can be found below.
Tamerx Diesel Products provides a replacement warranty on all of our parts. The duration and mileage limitations of the warranty vary by product and are specified on the product's detail page/item listing.
Please note that the warranty covers replacement of the part and the cost of shipping the replacement part to you only. It does not cover any shop, labor, towing, or any similar or related costs. This is not a "money back guarantee".
If you experience a problem with your part or it is not functioning properly, the correct warranty procedure is to call us at (510) 257-1777 (8:00 AM - 5:00 PM ET Monday through Friday). Be sure to have your order number and/or other relevant order information ready so we can easily locate your order and resolve your issue as quickly as possible. From that point, we will review with you any troubleshooting steps that may need to be taken and other areas or systems that can be checked to rule out external problems contributing to your part's issue.

As is the case for the majority of the diesel products sold on Tamerx Diesel Products, your part's warranty is active as soon as you install it. In some other cases, warranty activation is contingent upon you sending us your core (i.e., your old part). Tamerx Diesel Products will provide you a return shipping label for parts that have a warranty with a core return condition. When we have received your core return, the part's warranty coverage begins. We reserve the right to void the product warranty if your core is not received within the allotted time, or if it isn't received at all. If the warranty for the diesel part you are purchasing has a core return requirement, it will be clearly noted on the product detail page/item listing.
What is a Core Charge?
A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.
30 Day Core Charge Hold
You authorize Tamerx Diesel Products, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.
The customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Tamerx Diesel Products offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.
The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.
All fluids must be drained.
If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.
Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Tamerx Diesel Products core charge presented to you online today with your item is representative of the most common core charge.
Maintaining proper exhaust aftertreatment function is essential for modern diesel engines, and the Cummins X15 DOC Filter 2018–2024 (OEM 5417993) plays a key role in that process. This Diesel Oxidation Catalyst (DOC) filter helps reduce harmful emissions by converting hydrocarbons and carbon monoxide in the exhaust stream before they leave the system. Manufactured to meet original equipment specifications, it is designed for reliable fitment with 2018–2024 Cummins X15 engine applications. The durable construction allows it to withstand the high temperatures and demanding operating conditions typical of heavy-duty diesel environments. Replacing a worn or restricted DOC filter with the OEM 5417993 unit helps maintain proper exhaust system function and supports compliance with emissions regulations.

The Cummins X15 DOC Filter (Diesel Oxidation Catalyst), OEM 5417993, plays a vital role in the emissions system of many heavy-duty trucks built between 2018 and 2024. This component is designed to begin the treatment of exhaust gases as they exit the engine, helping reduce harmful pollutants before they pass through the rest of the aftertreatment system.
Installed early in the exhaust stream, the DOC filter uses a catalytic surface that reacts with certain compounds in diesel exhaust. This chemical reaction helps convert harmful gases into less harmful substances before the exhaust moves to the next stage of filtration.
Key Roles of the Cummins X15 DOC Filter 5417993
- Converts hydrocarbons (HC)
- in the exhaust into carbon dioxide and water vapor
- Reduces carbon monoxide (CO)
- produced during combustion
- Supports the operation of the Diesel Particulate Filter (DPF)
- by preparing exhaust gases for the next stage of treatment
- Helps maintain emissions compliance
- for heavy-duty diesel engines
- Maintains steady exhaust flow
- through the aftertreatment system
Because the DOC filter serves as the first step in the emissions control process, its condition can affect how efficiently the entire system operates. When functioning properly, the Cummins X15 DOC Filter OEM 5417993 helps ensure that exhaust gases are treated effectively before moving through additional filtration and emissions components.
A Diesel Oxidation Catalyst (DOC) filter is an important part of a diesel vehicle’s emissions system. Its job is to convert harmful gases in the exhaust into less harmful substances before they leave the tailpipe. When the DOC filter fails, it can lead to warning lights, exhaust system issues, and higher emissions.
The most common cause of DOC filter failure is contamination inside the catalyst. When certain substances enter the exhaust stream, they can coat the catalyst surface and prevent it from properly treating exhaust gases.
Several factors can lead to this type of contamination, including:
- Excessive soot buildup
- from incomplete combustion
- Oil entering the exhaust system
- due to engine issues
- Coolant leaks
- that introduce harmful deposits
- Low-quality fuel
- that leaves residue in the catalyst
- Unburned fuel
- reaching the exhaust because of engine problems
Driving habits can also contribute to the problem. Vehicles that are frequently used for short trips may not allow the exhaust system to reach temperatures high enough to burn off accumulated soot. Over time, this buildup can restrict exhaust flow and interfere with the DOC filter’s function.
Regular maintenance and early attention to engine problems can help prevent contamination and extend the life of the DOC filter.
The DOC filter functions as an early component in the exhaust aftertreatment assembly.
It helps process exhaust gases before they move through other emissions control components.
A technician can confirm compatibility by checking the OEM number 5417993 against the engine specifications.
