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.


Designed to meet original equipment specifications, the Caterpillar DPF OEM 20R8029 is engineered for proper fit and reliable emissions system function in compatible Caterpillar applications. This diesel particulate filter is responsible for capturing and storing soot from exhaust gases, supporting regulated emissions output and system efficiency. Manufactured with durable substrate materials and quality construction, it is built to withstand high exhaust temperatures and demanding operating conditions. Proper DPF function is essential for maintaining compliance with emissions standards and preventing system-related fault codes. Tamerx Diesel Products LLC supplies this Caterpillar DPF as a dependable solution for maintaining consistent exhaust aftertreatment operation.

Controlling diesel emissions is a critical requirement in modern heavy-duty equipment, and the Caterpillar DPF OEM 20R8029 plays a central role in that process. A Diesel Particulate Filter (DPF) is designed to capture and remove soot from exhaust gases before they exit the system.

The primary function of the Caterpillar 20R8029 DPF is to trap particulate matter produced during combustion. Diesel engines naturally generate soot, and without a filtration system, those particles would be released into the atmosphere.

The Caterpillar DPF OEM 20R8029 works by:

  • Capturing soot particles within its internal filter substrate
  • Reducing particulate emissions from the exhaust stream
  • Supporting compliance with emissions regulations
  • Working alongside sensors and control modules
  • Undergoing regeneration to burn off accumulated soot

Inside the DPF, exhaust gases pass through a ceramic honeycomb structure that traps soot while allowing cleaned gases to flow through. Over time, the filter fills with particulate matter and must go through a regeneration cycle. During regeneration, elevated exhaust temperatures convert the trapped soot into ash, restoring filter capacity.

The Caterpillar OEM 20R8029 DPF is engineered specifically for compatible Cat engines, ensuring proper fitment and integration with the exhaust aftertreatment system.

By maintaining effective soot filtration, this DPF helps protect air quality, support regulatory compliance, and keep Caterpillar-powered equipment operating within required emissions standards.

The Diesel Particulate Filter (DPF) is designed to capture and store soot from the exhaust system. Over time, it must regenerate to burn off that buildup. When regeneration does not occur properly, problems begin to develop.

The main cause of DPF failure is excessive soot accumulation due to incomplete regeneration.

Regeneration requires the exhaust system to reach high temperatures. If the vehicle is frequently driven on short trips or at low speeds, the DPF may not get hot enough to clear the trapped soot. As buildup increases, restriction inside the filter can lead to warning lights and reduced engine operation.

Other common contributing factors include:

  • Faulty temperature or pressure sensors
  • Malfunctioning EGR system
  • Poor fuel quality
  • Excessive idling
  • Oil or coolant entering the exhaust system
  • Ignoring early DPF warning lights

When soot accumulation becomes severe, the filter can clog beyond recovery. At that point, forced regeneration or replacement may be necessary.

Routine maintenance and addressing engine issues early are critical. Keeping the engine running properly helps ensure the DPF can complete regeneration cycles as designed and avoid premature failure.

The 20R8029 DPF traps and removes soot and particulate matter from exhaust gases.

The Caterpillar 20R8029 DPF is engineered for direct replacement on compatible applications.

Verifying 20R8029 ensures the correct DPF for your Caterpillar engine’s emissions configuration.

The 20R8029 DPF is installed in the exhaust system downstream of the engine’s turbocharger.
