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.

In a diesel aftertreatment system, even the smallest components play a major role in keeping everything running smoothly. The Cummins aftertreatment hose (pressure sensing tube) is designed to transfer pressure signals between exhaust components and sensors. This allows the engine control module (ECM) to accurately monitor system conditions and make the adjustments needed to maintain proper emissions control and engine balance.
- Transfers Pressure Signals for Accurate Monitoring
The hose carries pressure data from the exhaust system to sensors, helping the ECM understand how the aftertreatment system is performing. - Supports Reliable Sensor Communication
A stable connection ensures that sensors provide consistent and accurate readings, which are essential for proper system adjustments. - Plays a Role in DPF and SCR Efficiency
Pressure readings help determine soot levels and exhaust flow, supporting proper operation of components like the DPF and SCR systems. - Designed for Cummins Applications (2018–2024)
Built to OEM 4394336 specifications, this hose is engineered for compatibility with Cummins engines and their factory aftertreatment setups. - Built to Withstand Harsh Operating Conditions
Constructed from durable materials, the hose is designed to handle heat, vibration, and continuous use within the exhaust environment.
The aftertreatment hose may be a simple connection, but it plays a critical role in system accuracy and performance. In Cummins engines, a dependable hose helps maintain proper pressure feedback, supports emissions control, and keeps the entire aftertreatment system functioning as intended.
Yes, debris or residue can interfere with proper flow inside the hose.
