Racor R45P 30 Micron Spin-On Fuel Filter/Water Separator Element for 445R & 645R

Racor R45P is a genuine 30-micron spin-on replacement element for Racor 445R and 645R diesel spin-on fuel filter/water separator assemblies. It uses Racor Aquabloc® media to repel water and remove dirt, rust and other contaminants from diesel fuel before they reach sensitive fuel-system components.

Fitment Notes

This is a replacement spin-on element only. It does not include the mounting head, bowl, drain, priming pump or mounting hardware.

Before ordering, check the model number on your filter head. The R45P fits Racor 445R and 645R assemblies with a 1"-14 mounting thread. You can reuse your existing bowl. Just move it from the old element to the new one, and put in a new bowl seal if the old one is worn.

Application

The 30-micron rating is commonly used for primary fuel filtration. It removes larger particles before fuel reaches a finer secondary filter downstream. If this will be the last filter before the engine, check the rating the engine manufacturer requires before choosing an element.

Changing fuel filter elements at the recommended service intervals helps protect the fuel system from water and contamination. These can restrict fuel flow, reduce performance and wear out fuel-system parts early.

Other Micron Ratings

Racor elements are color-coded by micron rating:

• R45S: 2 micron (brown), for final filtration

• R45T: 10 micron (blue), for primary or secondary filtration

• R45P: 30 micron (red), for primary filtration (this item)
