SHIPPING POLICY
Tamerx Diesel Products ships via UPS Ground. Next day air shipping can be arranged for a reasonable price of anywhere from $50.00 - $100.00 depending on the weight of the product and your location. We will do everything we can to make sure that you get the service you need. We understand how important it is to receive your order as quickly as possible.
In most cases Tamerx Diesel Products only needs one address, as long as your product is shipping to the same location as your billing information. In order to eliminate credit card fraud, your billing information must match the credit card you provide.
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. If a replacement is determined to be necessary, we will then arrange for your replacement part to ship out ASAP and issue any necessary return shipping labels and/or documents.
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.
Built for Cummins ISL engine applications, this Diesel Oxidation Catalyst (DOC) is manufactured to meet original equipment specifications for accurate fit and dependable aftertreatment system function. The DOC works within the exhaust stream to convert hydrocarbons and carbon monoxide into less harmful emissions before reaching downstream components. Constructed with durable catalyst materials and a heavy-duty housing, it is engineered to withstand high exhaust temperatures and demanding operating conditions. Proper operation of the DOC is essential for supporting emissions compliance and maintaining overall exhaust system efficiency. Tamerx Diesel Products LLC supplies this Cummins ISL DOC as a reliable solution for consistent and dependable aftertreatment performance.

Proper maintenance of your Cummins ISL Diesel Oxidation Catalyst (DOC) OEM 5287491RX is essential for keeping your aftertreatment system operating efficiently. The DOC plays a key role in converting harmful exhaust gases and supporting downstream components like the DPF.
Although the DOC does not trap soot like a DPF, it still requires attention to ensure it functions correctly over time.
To properly maintain your Cummins ISL DOC:
- Follow manufacturer-recommended service intervals
- Address check engine lights or fault codes promptly
- Maintain proper fuel quality to reduce contamination
- Keep the EGR and fuel injection systems in good condition
- Inspect exhaust connections for leaks or loose clamps
- Ensure sensors in the aftertreatment system are functioning correctly
Clean combustion is critical for DOC longevity. Poor fuel quality or malfunctioning injectors can introduce excessive hydrocarbons into the exhaust, which may affect catalyst efficiency.
It’s also important to avoid prolonged operation with unresolved engine issues, as incomplete combustion can impact exhaust system components.
If you notice increased exhaust odor, warning lights, or reduced efficiency in the aftertreatment system, diagnostics should be performed immediately to prevent further complications.
By maintaining the overall health of your engine and exhaust system, you help protect your Cummins ISL DOC OEM 5287491RX and support consistent emissions control and reliable operation.
The Diesel Oxidation Catalyst (DOC) is designed to convert harmful exhaust gases into less harmful emissions. It operates under high heat and relies on clean exhaust flow to function properly. When it fails, the issue is often tied to contamination.
The main cause of DOC failure is internal contamination of the catalyst substrate.
When engine oil or coolant enters the exhaust system, it can coat the catalyst surface. This prevents the chemical reaction inside the DOC from occurring efficiently. Over time, the catalyst becomes less effective and may trigger efficiency fault codes.
Other common contributing factors include:
- Excessive soot from incomplete combustion
- Prolonged engine misfires
- Faulty fuel injectors
- EGR system malfunction
- Repeated overheating events
- Ignoring warning lights
Overheating can also damage the internal structure of the DOC. If exhaust temperatures rise too high for extended periods, the substrate can crack or melt, restricting exhaust flow.
Short trips that prevent the exhaust system from reaching proper operating temperature may also contribute to buildup over time.
Routine engine maintenance and addressing oil or coolant leaks quickly can significantly reduce the risk of DOC failure and help maintain proper exhaust system function.
The Cummins ISL DOC is a diesel oxidation catalyst that helps convert harmful exhaust gases into less harmful substances before they reach downstream emissions equipment.
The ISL DOC is installed in the exhaust stream between the turbocharger outlet and the particulate filter or SCR system.
The DOC initiates chemical reactions that reduce hydrocarbons and carbon monoxide in the exhaust gas.
Yes, the Cummins ISL DOC is designed to be serviced or replaced independently when needed.
