If you are searching for a WF2127 cross reference, you probably need a replacement for this spin-on coolant filter, or you want to know which part numbers cover the same filter. One point comes first: the WF2127 is a coolant filter for the engine cooling system. It is not an oil filter, a fuel filter or a fuel water separator. This guide lists the numbers that appear together in public cross-reference data, explains how to read them, and shows how to avoid ordering the wrong filter.
IXIN Filter has made filters since 2010, including a wide range of coolant filters for trucks, buses, construction and agricultural machinery. The checks below come from questions our buyers ask every week.
What Is the WF2127 Coolant Filter?
The WF2127 is a spin-on coolant filter. In its original form it contains no chemical additive and is commonly cross-referenced to Cummins engines. Published data lists these dimensions:
| Attribute | Detail |
|---|---|
| Filter Type | Spin-on coolant filter |
| Chemical Additive | None (non-chemical type) |
| Overall Height | 146.3 mm (5.76 in) |
| Largest Outside Diameter | 93.73 mm (3.69 in) |
| Seam Outside Diameter | 95.76 mm (3.77 in) |
| Thread Size | M36 x 2-6G (internal) |
Different sources round the outside diameter differently, so always measure your old filter and confirm the dimensions with your supplier before ordering.
WF2127 Cross Reference Table
The table lists part numbers that appear together in public cross-reference data. Use it as a starting point, not as a guarantee.
| Brand | Part Number |
|---|---|
| Fleetguard | WF2127 |
| Cummins | 3680434 |
| Baldwin | B5087 |
| Donaldson | P550867 |
| WIX | 24113 |
| Fram | PR8694 |
| HiFi | WE2127 |
| Luber-finer | LFW2127 |
Reference numbers are listed for identification only. All brand names belong to their respective owners, and IXIN is not affiliated with them. One source lists a different Donaldson number for this filter, so confirm the exact match with your supplier.
How to Use a WF2127 Cross Reference Safely
A cross reference shows which part numbers other sources have matched. It does not prove that two filters are identical. Follow these steps each time.
Step 1: Start from the number on the old filter
Read the number printed on the filter you are replacing, then look for it in the table. If your number is missing, send it to your supplier instead of guessing.
Step 2: Check the chemical additive type
This is the most important step for coolant filters. Some coolant filters contain an additive (often called DCA) that is released into the coolant, while others, like the WF2127, contain none. Use the same type as your old filter and your coolant specification. Our WF2071 coolant filter page shows an example of an additive type.
Step 3: Confirm the thread
The WF2127 uses an M36 x 2 thread. Other coolant filters use different threads, for example the WF2096 uses M16 x 1.5. A filter that looks similar will not screw onto the wrong filter head.
Step 4: Compare dimensions and gasket
Measure the height and outside diameter of the old filter, and check the gasket. A small difference can cause leaks.
Step 5: Ask for a sample or a drawing
For bulk orders, ask for a drawing and a sample, then test-fit the sample before placing a larger order.
Common Mistakes When Using a WF2127 Cross Reference
Even experienced buyers make these errors:
- Searching for the wrong filter type: the WF2127 is a coolant filter, not an oil or fuel filter, so check the type before ordering
- Ignoring the additive type: a filter with additive and one without are not interchangeable in every system
- Mixing similar numbers: WF2127, WF2071 and WF2096 are different filters with different threads and additive types
- Trusting one source only: cross-reference sites sometimes disagree, so compare at least two
- Treating cross references as guarantees: they are a guide, and you are responsible for confirming fit
For another example of the same approach, see our FS20083 cross reference guide for fuel filters and our P637453 cross reference for air filters.
Why Buyers Choose a Factory-Direct Replacement
Distributors and fleets often replace branded filters with factory-direct alternatives because:
- One replacement item can cover several brand numbers, which simplifies inventory
- Lead times are shorter when you deal with the manufacturer
- Filter paper, metal thickness and packaging can be adjusted to your market
- Pricing is more predictable on repeat orders
When you compare suppliers, look for test data, sample support and clear fitment information. Our guides on how to audit a truck filter supplier in China before placing an order and how to choose an OEM truck filter factory explain what to ask for.
