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.


Integrated into the factory exhaust aftertreatment system of Cummins ISB 6.7L engines from model years 2013–2021, OEM 61026B is an SCR filter designed to support emissions control through selective catalytic reduction. This component facilitates the reduction of nitrogen oxides within the exhaust stream before gases exit the system. Manufactured to OEM specifications, it ensures proper fitment and compatibility with existing aftertreatment assemblies. Built from durable materials, it is suited for the high-temperature operating conditions common in medium- and heavy-duty diesel applications. It is a reliable option for fleet service and targeted repair needs requiring dependable aftertreatment system function.

The Cummins ISB 6.7L SCR Filter 2013–2021: OEM 61026B works as a key component of the engine’s Selective Catalytic Reduction (SCR) aftertreatment system. Its primary function is to chemically treat nitrogen oxide (NOx) emissions in the exhaust stream before the gases exit the vehicle.

As exhaust leaves the engine, it passes through upstream aftertreatment components such as the Diesel Oxidation Catalyst (DOC) and Diesel Particulate Filter (DPF). After this stage, Diesel Exhaust Fluid (DEF) is injected into the exhaust stream by the DEF doser injector. The heat of the exhaust causes the DEF to break down into ammonia.

Here’s how the SCR filter functions in the process:

  • DEF is injected upstream into hot exhaust gases
  • DEF converts into ammonia
  • Exhaust and ammonia enter the SCR catalyst
  • A chemical reaction converts NOx into nitrogen and water vapor

Inside the SCR filter (OEM 61026B), a catalyst-coated substrate facilitates this reaction. The catalyst allows ammonia to react with nitrogen oxides, reducing harmful emissions before they are released.

Sensors positioned before and after the SCR monitor exhaust conditions and NOx levels. The engine control module uses this data to adjust DEF dosing and maintain proper system function.

Designed specifically for 2013–2021 Cummins ISB 6.7L engines, OEM 61026B plays a vital role in emissions compliance, exhaust treatment efficiency, and reliable aftertreatment system operation.

When your SCR filter is failing, immediate and accurate diagnosis is essential to prevent engine derates, emissions violations, and costly component replacement. The SCR system is responsible for reducing NOx emissions, and when it loses efficiency, performance and compliance are directly affected.

The first step is to perform a full diagnostic scan and review SCR efficiency codes, NOx sensor readings, DEF dosing data, and exhaust temperature values. Many SCR failures are caused by DEF quality issues, sensor faults, or dosing problems rather than permanent catalyst damage.

Midway through troubleshooting, focus on these critical checks:

  • Verify DEF quality meets ISO 22241 standards
  • Inspect DEF injector for crystallization or blockage
  • Confirm proper DEF pump pressure and delivery
  • Test NOx sensors for accuracy and response time
  • Check for coolant or oil contamination in the exhaust
  • Review regeneration history and exhaust temperature trends

If contamination, dosing failure, or sensor issues are identified, correct those problems first and clear the codes. In many cases, SCR efficiency can be restored once the root cause is repaired.

If efficiency codes persist after confirming DEF quality, proper dosing, and accurate sensor readings, the SCR catalyst may be poisoned or thermally damaged and require replacement. Before installing a new unit, correct all upstream issues to prevent repeat failure and ensure long-term emissions system reliability.
