Racor R120T 10-Micron Diesel Fuel Filter Element
Racor R120T is a 10-micron spin-on replacement element for the Racor 4120R diesel fuel filter/water separator. It renews the filtration element while the serviceable mounting head and bowl remain in use. Racor technical reference.
Key Features
- Filtration grade: 10 microns
- Replacement element for Racor 4120R
- Spin-on fuel filtration and water-separation service
- Manufacturer part number: R120T
Product Compatibility
Match the Racor 4120R assembly identification and the complete installed element number. This element is not a complete filter/head assembly.
When This Part Needs Replacement
Replace the element at the engine or filter service interval, or sooner when fuel restriction reaches the specified limit. Repeated early blockage calls for checking the fuel supply and tank contamination.
Installation Notes
Shut down and isolate the fuel supply before service. Clean the sealing faces, inspect the reusable bowl and fit the correct seals. Prime and bleed as directed by the filter manual, then check for fuel leaks and air entry.

Parts Desk Insight
The T suffix identifies this 10-micron version. Match both the 4120R housing and the filtration grade specified for your engine; changing to a finer element without checking the system can increase restriction.
