4759205 Engine Oil Filter Primary for Perkins 4006-23TAG3A: Worldwide Buyer's Guide
Table of Contentsexpand_more
The 4759205 ENGINE OIL FILTER PRIMARY is the OEM-specified full-flow lube-oil element for the Perkins 4006-23TAG3A diesel engine, filtering the entire oil pump output before it reaches the main bearings, turbocharger and valve train. It is a direct-replacement maintenance part, not a universal spin-on, so fitment must be confirmed against the engine serial number.
A primary engine oil filter is a full-flow filtration element installed on the pressure side of a diesel engine's lubrication circuit, capturing wear metals, soot and sludge before oil reaches bearings and the turbocharger. On the Perkins 4006-23TAG3A — a 23-litre, six-cylinder turbocharged and air-to-air charge-cooled industrial diesel — the 4759205 element is the first line of defence for the lube system.
Perkins, like other major engine OEMs such as Cummins and Caterpillar, publishes filter specifications tied to engine serial ranges rather than to a single model name. That is why a filter that physically threads onto a 4006-23TAG3A may still be the wrong element if its bypass-valve cracking pressure or filtration efficiency differs from the OEM specification.
What does the 4759205 filter actually do on a Perkins 4006-23TAG3A?
The 4759205 element sits in the primary full-flow position. Every drop of oil leaving the pump passes through it before reaching the bearings, camshaft and turbocharger feed line.
Its job is threefold: capture hard wear particles that would score bearing shells, hold soot and oxidation products in suspension until the next drain, and maintain a low enough pressure drop that oil flow is not starved at cold start. A secondary or bypass filter, where fitted, handles finer soot removal at a much lower flow rate.
Because the 4006-23TAG3A is a turbocharged engine, the filter also protects the turbocharger centre housing, which is far less tolerant of contaminated oil than a naturally aspirated bearing set.
Which specifications must match before you order?
Four parameters decide whether a filter is a genuine fit: thread and seal geometry, bypass-valve cracking pressure, filtration efficiency, and collapse/burst pressure rating. A filter that matches only the first is a false economy.
| Parameter | What to confirm | Why it matters |
|---|---|---|
| Thread size | Confirm against engine serial plate (e.g. 3/4-16 UNF, 1-12 UNF) | Wrong thread = no seal, oil loss, engine damage |
| Bypass valve setting | Typically 1.0–2.5 bar cracking pressure | Too low = unfiltered oil bypasses; too high = oil starvation at cold start |
| Filtration efficiency | Nominal 10–25 micron range for full-flow diesel elements | Determines wear-particle capture and drain interval |
| Collapse pressure | Minimum 5 bar differential | Prevents element collapse on cold-start pressure spikes |
| Operating temperature | Continuous 120 °C / 248 °F oil temperature | Media and gasket must survive sustained hot-oil exposure |
Where the OEM datasheet is unavailable, cross-reference the Perkins part number against the engine serial range rather than the model name alone. Perkins builds the 4006 family in several ratings, and filter specification can change mid-series.
How does a full-flow diesel oil filter work?
Oil is drawn from the sump by the pump, pushed through the 4759205 element from the outside in, and returned to the main gallery. A spring-loaded bypass valve opens only if the element becomes blocked or the oil is too cold to flow.
That bypass valve is the safety feature most often overlooked by buyers. A cheap filter with a low cracking pressure will quietly send unfiltered oil to the bearings for the first minutes of every cold start — exactly when wear is highest.
On turbocharged engines such as the 4006-23TAG3A, the same oil feed also cools the turbocharger bearing housing, so flow rate matters as much as filtration efficiency.
Which filter type suits your application?
Full-flow primary elements are the standard choice for diesel engine protection. Bypass (secondary) elements are added where extended drain intervals or severe soot loading demand finer filtration.
In compressed-air and process plants, the same filtration logic appears in a different form: coalescing and activated-carbon filters remove oil aerosols and vapour from air rather than from lube oil. Buyers specifying both engine and plant filtration often source them together.
- Full-flow primary (4759205 class): protects bearings and turbocharger; changed at every oil drain.
- Bypass/secondary: finer soot removal, typically changed at half the primary interval.
- Coalescing air filters: remove oil aerosols from compressed air — e.g. WILKERSON M26-03-FM0 Coalescing Filter at 0.01 micron and 65.5 cfm.
- Activated-carbon air filters: remove oil vapour and odour — e.g. SPEEDAIRE Activated Carbon Compressed Air Filter at 117 cfm and 235 psi.
How to select the right 4759205 replacement
- Read the engine serial plate first. Perkins ties filter specification to serial range, not model name alone.
- Match thread and seal geometry. Confirm the thread callout and gasket diameter before ordering.
- Verify bypass-valve cracking pressure. It should match the OEM figure, typically in the 1.0–2.5 bar band.
- Check filtration efficiency and collapse rating. A 10–25 micron nominal element with at least 5 bar collapse resistance is the baseline for a turbocharged industrial diesel.
- Confirm duty cycle and environment. Continuous prime-power duty in high ambient temperatures shortens drain intervals.
- Plan the logistics. For worldwide supply, confirm export documentation, HS code and freight mode before the filter is needed, not after.
Comparison: filtration products stocked by 3G Electric
The table below shows the filtration ladder 3G Electric stocks across engine-adjacent and compressed-air duties. The 4759205 element itself is quoted on request against your engine serial number.
| Product | Function | Connection | Flow / rating | Max pressure |
|---|---|---|---|---|
| WILKERSON M21-03-F00 Coalescing Filter | Oil and particulate removal, light duty | 3/8 in NPT | 95.4 cfm | 150 psi |
| SPEEDAIRE AF-050X Coalescing Filter | Oil and particulate removal, general duty | 1/2 in NPT | 61 cfm | 290 psi |
| SPEEDAIRE Pneumatic Oil Filter | Oil aerosol removal, pneumatic circuits | 1 in NPT | 147 cfm | 290 psi |
| WILKERSON M30-08-FM0 Coalescing Filter | Oil aerosol removal, instrumentation and painting | 1 in NPT | 203 cfm | 200 psi |
| PARKER AAPX045INFX Coalescing Filter | High-purity air, heavy duty | 2 1/2 in NPT | 699 cfm | 232 psi |
| PARKER ACSPX035GNMX Activated Carbon Filter | Oil vapour and odour removal | 1 1/2 in NPT | 339 cfm | 290 psi |
Step up the ladder when flow demand rises or when downstream equipment is more sensitive: a 3/8 in NPT coalescing filter suits a single pneumatic control loop, while a 2 1/2 in NPT unit at 699 cfm suits a plant-wide instrument-air header. For engine lube-oil protection, the equivalent step-up is from a standard full-flow element to a combined full-flow plus bypass arrangement.

Frequently asked questions
How do I confirm the 4759205 filter fits my Perkins 4006-23TAG3A? Check the engine serial plate and cross-reference the Perkins part number against the serial range, not the model name alone. Confirm thread size, bypass-valve cracking pressure and gasket diameter before ordering.
What is the difference between a primary and a secondary oil filter? A primary (full-flow) filter handles 100% of pump output and protects bearings and the turbocharger. A secondary (bypass) filter takes a small slipstream at finer efficiency, removing soot that the full-flow element cannot.
Where can I buy the 4759205 filter in Worldwide? 3G Electric supplies the 4759205 primary engine oil filter and related filtration products worldwide, with export documentation and freight coordination handled in-house. Contact us with your engine serial number for a quote.
What lead time should I expect for worldwide delivery? Lead time depends on stock position and destination. 3G Electric confirms availability and freight mode at quotation stage, and can advise on air versus sea freight for urgent maintenance windows.
Can I source engine and compressed-air filters from the same supplier? Yes. 3G Electric stocks both engine-adjacent filtration and compressed-air coalescing and activated-carbon filters, so a single enquiry can cover the engine lube circuit and the plant air system.
