423-8524 oil and water separator for fuel filter element

Product Description

423-8524 Oil-Water Separator for Fuel Filter Element is a precision-engineered filtration component designed specifically for 

diesel fuel systems, hydraulic power units, and industrial fuel storage applications where effective removal of free water, 

emulsified water, and particulate contaminants is critical. This fuel filter element employs a high-performance folded pleat 

configuration that maximizes filtration surface area within a compact footprint, delivering exceptional separation efficiency 

with minimal flow resistance.

423-8524 Oil-Water Separator for Fuel Filter Element features rigorously selected end caps manufactured to exacting dimensional

 standards, ensuring seamless compatibility with OEM fuel filtration housings. The installation process is straightforward and 

tool-friendly, significantly reducing downtime during scheduled maintenance intervals. The end caps are precision-machined 

with tight tolerances, eliminating bypass leakage and ensuring that all fuel flow passes through the active filtration media.

423-8524 Oil-Water Separator for Fuel Filter Element is constructed with thickened, heavy-gauge metal components that

 provide superior pressure resistance. This robust construction withstands the demanding operating conditions commonly 

found in heavy-duty diesel engines, marine fuel systems, and industrial power generation equipment. The enhanced structural 

integrity translates directly to extended service life – significantly outlasting standard-grade filter elements in comparative

 field tests.

423-8524 Oil-Water Separator for Fuel Filter Element delivers outstanding filtration performance characterized by high flow

 capacity, low pressure drop, and consistent separation efficiency. Its optimized pleat geometry and advanced coalescing 

media ensure that water droplets are effectively coalesced and separated from the fuel stream, while particulate contaminants

 are captured with high precision. The balanced design achieves an ideal compromise between filtration fineness and flow

 dynamics – ensuring reliable engine protection without compromising fuel delivery rates.

FAQ – Frequently Asked Questions

Q1: What is the difference between an oil-water separator and a standard fuel filter element?

A1: 423-8524 Oil-Water Separator for Fuel Filter Element is specifically designed with coalescing media that causes fine water 

droplets to merge into larger droplets that gravity-separate and settle into the collection bowl. Standard fuel filters primarily

 remove particulate contaminants but have limited water separation capability. This element combines both functions – 

particulate filtration plus active water coalescing – in a single unit.

Q2: How does the 423-8524 achieve water separation from diesel fuel?

A2: 423-8524 Oil-Water Separator for Fuel Filter Element uses a two-stage mechanism: (1) coalescing layer – fine water droplets 

are forced to merge into larger droplets as fuel passes through the media; (2) separation layer – the enlarged droplets are 

repelled by the hydrophobic screen and fall by gravity into the collection reservoir, while clean, dehydrated fuel continues 

downstream.

Q3: What is the recommended replacement interval for the 423-8524?

A3: Replacement interval depends on fuel quality and operating hours. Under typical conditions (ASTM D975 diesel with ≤500 

ppm water), recommended interval is 500–1,000 operating hours or every 6–12 months. Always monitor differential 

pressure – replace when ΔP reaches 1.5–1.8 MPa regardless of time.

Q4: Can the 423-8524 Oil-Water Separator for Fuel Filter Element be used with biodiesel or synthetic fuels?

A4: Yes, 423-8524 Oil-Water Separator for Fuel Filter Element is compatible with B20 biodiesel blends, renewable diesel, 

and most synthetic fuel formulations. For higher biodiesel blends (B50–B100), we recommend consulting our technical team for 

media compatibility verification, as higher ester content may affect elastomer seals.

Q5: What is the maximum operating temperature for the 423-8524?

A5: 423-8524 Oil-Water Separator for Fuel Filter Element operates continuously within 1°C to 100°C. For applications exceeding 

100°C (e.g., hot fuel return lines), we offer a high-temperature variant with upgraded seals – please specify when ordering.

Q6: How do I know when the 423-8524 needs replacement?

A6: Key indicators: (a) differential pressure gauge reading reaches 1.5–1.8 MPa; (b) visible water breakthrough at the fuel outlet 

(indicates media saturation); (c) engine performance degradation (rough running, loss of power); (d) scheduled maintenance 

interval based on operating hours. Do not wait for complete blockage – replace proactively.

Q7: Is the 423-8524 Oil-Water Separator for Fuel Filter Element compatible with competitive housing brands?

A7: Yes, 423-8524 Oil-Water Separator for Fuel Filter Element is manufactured to industry-standard dimensions, ensuring direct

 interchangeability with leading OEM housings from Caterpillar, Cummins, Detroit, Perkins, and other major brands. 

We recommend verifying your housing's specific dimensions before ordering.

Q8: What is the filtration accuracy range and how do I choose?

A8: 423-8524 Oil-Water Separator for Fuel Filter Element is available in accuracy grades from 1 μm to 100 μm. Selection depends 

on your fuel system's injector clearances:

· 1–5 μm – Common rail, high-pressure injection systems

· 10–30 μm – Mechanical injection, older diesel engines

· 50–100 μm – Coarse primary separation / transfer applications

Contact our technical team for recommendation based on your engine model.

Q9: What quality certifications does the 423-8524 carry?

A9: 423-8524 Oil-Water Separator for Fuel Filter Element is manufactured under ISO 9001 quality management standards. 

Products undergo 100% pressure integrity and dimensional inspection before shipping. Material certificates and test reports are 

available upon request.

Q10: What should I do if the element shows high pressure drop shortly after installation?

A10: Possible causes: (a) contaminated fuel loading the element rapidly; (b) incorrect element orientation (reverse flow); 

(c) housing gasket leakage causing bypass; (d) media damage during installation. Check the housing for proper installation, 

inspect fuel quality, and verify that the flow direction arrow matches your system. Contact our support team for diagnostics.

Q11: Can the 423-8524 be cleaned and reused?

A11: No, 423-8524 Oil-Water Separator for Fuel Filter Element is a disposable component. The coalescing and separation media 

are not cleanable – washing or blowing damages the fiber structure, permanently reducing efficiency and risking media bypass.

 Replacement is the only recommended practice for reliable water separation.

Q12: How should the 423-8524 be stored before use?

A12: Store in a cool, dry, dust-free environment away from direct sunlight, moisture, and chemical fumes. Keep in original sealed 

packaging until installation. Ideal conditions: 5–35°C, humidity <65%. Shelf life is 36 months from manufacturing date under 

proper storage.

Q13: What is the warranty coverage for the 423-8524 Oil-Water Separator for Fuel Filter Element?

A13: We provide a 12-month warranty against manufacturing defects in materials and workmanship. The warranty does not 

cover: (a) damage from operation beyond specified temperature or pressure limits; (b) physical damage during installation; 

(c) fuel contamination beyond normal operating conditions; (d) failure to replace at recommended ΔP.

Q14: Do you offer bulk pricing for fleet or maintenance contract orders?

A14: Yes, we offer volume discounts for fleet operators, maintenance service providers, and OEM accounts. Please contact our 

sales team with your estimated annual consumption for a customized quotation.

Q15: How quickly can I receive replacement 423-8524 elements?

A15: Our regional warehouses maintain stock of high-demand models. Standard orders ship within 24–48 hours (domestic)

 and 3–5 business days (international). For emergency next-day delivery, please contact our customer service team to confirm 

availability.
