UFI Filters 26.052.00 Diesel Filter
Product description
What this filter is and what it may do for you
The UFI Filters 26.052.00 Diesel Filter is a dedicated diesel filtration element designed to support water separation in fuel systems. It’s presented as an exclusive product backed by two UFI patents that focus on a water separation approach using coalescence, triggered by changes in fluid velocity as it moves through the filter medium. In practical terms, this means the element is structured to help keep water droplets apart from diesel as fuel travels through the system, a factor that can matter for engine reliability, especially in environments where moisture ingress is a concern.
Technical profile at a glance

On the dimensional side, the component lists: Length A 93.0, Width B 21.0, Inner diameter at the bottom C 9.0, Largest diameter D 66.0, Height H 116.0. These figures describe the size envelope of the filter and help determine compatibility with a given housing. The data provided is intentionally concise, if you’re selecting spares, you’ll want to confirm the exact fit against your equipment’s OEM housing and any service manual guidance.
How it works, on paper


The core claim is water separation through a coalescence-based mechanism. The concept relies on fluid dynamics within the filter media—when diesel containing humidity passes through, water droplets are encouraged to merge and separate from the fuel phase as velocity shifts occur. This is part of a broader class of filters that aim to reduce water carryover in the fuel line, potentially contributing to cleaner combustion and lower risk of water-induced corrosion or microbial growth in the tank. It’s worth noting that the description frames this as an exclusive patented approach, which may appeal to buyers seeking a distinctive water-management solution in the filtration chain.

Practical considerations for choosing this part
If you prioritise water separation performance as part of your fuel cleanliness strategy, this filter presents a plausible option to consider. It’s not a generic element, the emphasis on two patents and ISO 16332 compliance hints at a defined testing and design philosophy around water/diesel separation. However, the data provided does not include filtration rating, micron size, or flow capacity. Those specifications are crucial to assess whether the unit matches your system’s operating conditions and service interval expectations. Without them, it’s sensible to compare fit, compatibility, and service requirements against your existing setup.
Pros and potential limitations in use

What stands out: the claim of a dual-patent solution and ISO 16332 compliance suggests a structured approach to managing water in diesel. For systems where water content is a known concern, such a feature could be beneficial as part of a broader maintenance plan. What may give you pause: the absence of detailed performance metrics such as recommended replacement intervals, filtration efficiency at specific micron ratings, or maximum flow rates. For some users, that means you’ll need to rely on your OEM guidance or supplier recommendations to ensure the part will perform within expected service windows.


Who it’s for and who should think again
This filter could suit operators who want to align their fuel conditioning with a water management strategy and prefer manufacturer-backed engineering claims around separation. It may be less compelling if your system requires very specific micron filtration data, or if you rely on a filter with a longer track record of field performance data published by third parties. If you’re seeking a drop-in replacement that you can verify from your service schedule or a known compatibility list, confirm housing compatibility and any seal or gasket requirements with the supplier before purchase.

Before you buy: what to check
- Confirm the exact housing compatibility and mounting interface against your current setup.
- Look for any required seals or accessories that may be sold separately.
- Seek out a data sheet or supplier guidance that provides micron ratings, filtration efficiency, and maximum operating pressure, if available.
- Check whether your fuel conditions (for example, moisture levels or ambient storage conditions) align with the intended use of water separation systems described by ISO 16332.
Practical usage example



Imagine a service scenario where you periodically drain water from a diesel system or monitor fuel quality at the tank level. In such a case, having a filter that explicitly targets water separation through a coalescence process could help reduce moisture backflow into the fuel line. The effect, in everyday terms, might be a small but meaningful reduction in fuel-water emulsions reaching the injector train, which could translate to steadier engine performance during adverse conditions.
Quick comparison: what this approach implies versus alternatives
If you weigh this option against simpler, conventional diesel filters, the emphasis here is on water management as a feature rather than a broad statement about filtration efficiency alone. For users who already have a robust fuel conditioning regime and rely on precise micron filtration, you’ll want to verify that the 26.052.00 aligns with your target specs. If you prioritise proven, data-backed performance for a wide range of operating environments, you may also consider how this solution stacks up against other water-separation approaches in terms of field data and service intervals.

FAQ (based on available information)
- Q: Does this filter specify a micron rating? A: The provided information does not include micron ratings or exact filtration efficiency data.
- Q: Is it compatible with all diesel systems? A: Compatibility depends on housing dimensions and mounting interface, verify fit against your equipment manual.
- Q: What does the ISO 16332 compliance imply for my maintenance schedule? A: It indicates a water/ diesel separation approach aligned with a recognised standard, but exact service intervals aren’t stated here.
- Q: Are there extra parts required for installation? A: The material notes do not specify seals or accessories, check with the supplier for a complete install kit.
- Q: Is the product backed by field performance data? A: The description highlights patents and compliance but does not cite field test results.
Is it worth it?
Worth considering if water management in your diesel fuel is a priority and you can verify housing compatibility and supported service guidance. If your system relies on well-documented filtration metrics (micron rating, flow, pressure) or you need broader field performance data, you may want to compare with other options or request 추가 data from the seller before committing.
